ASP.NET Controls Filter the Data View

Artigo
03/05/2007

John Hey there,

My name is John Jansen and I'm one of the Test Leads for the SharePoint Designer (SPD) product group. My specialty is data presentation and application building. But I also love to play around with CSS and generic ASP.NET controls. I plan to post tips and tricks here based on questions I see asked in Newsgroups as well as Discussion Boards inside Microsoft.

This first tip is about inserting an ASP.NET control onto a page in SharePoint Designer and then using that control as the mechanism for filtering a Data View on the page. For the purposes of this post, I'm using a DropDownList control because that seems to be the one most people ask about, but you could use a TextBox or CheckBox or anything else and get similar results. The scenario here is that you have a bunch of Categories and a bunch of Products that fit into those Categories, and you want to use a DropDownList to show Products for a specific Category.

To begin, create two lists in the browser: Categories with a field of CategoryName and Products with a field of CategoryName as well (I use a Lookup field type for simplicity, but it doesn't have to be - this code does a simple string compare). Then fill out the lists so you have more than one item in each.

This tip also assumes you already know how to open your Site in SPD and you have created a new page. I realize it is a lot of steps, but I believe they are pretty straight forward as you perform them...

Place your page into design view
Click Task panes :: Data Source Library
Click the data source called Categories
Click to Insert Data Source Control
If prompted, click “Yes” to display the control
Place insertion point below this control
Click Insert :: ASP.NET Controls > Drop Down List
Click the Smart Panel :: Choose Data Source...
Choose the Data Source (for example, SPListDataSource1)
Tell it to display "CategoryName" (or the field that contains your category name)
Make its value "CategoryName"
Click OK
Click to select the dropdownlist control
Click the Smart Panel :: AutoPostBack == True
Drag and drop the Products list onto a page to create a Data View
Clck the Smart Panel :: Edit Columns to add and remove the columns you want to display
Click Data View :: Filter
Create the following filter:
                Field: CategoryName (or the field that contains your category name)
                Comparison: Equals
                Value: [Create a new Parameter]
                                Param Name: Param1
                                Source: Control
                                Control ID: DropDownList1
                                Default: Beverages
Click OK
Click OK again
Save the page
Preview in the browser
Make a change to the DropDownList control

OK. That should do it! Good luck.

-John

Thanks for the tip. Have you looked at whether it is possible or if there are any issues with Ajax enabling this solution with the UpdatePanel? Thanks, Barry

Glad to hear it. It would be nice not to pull back down the master page on a refresh within the UpdatePanel. Barry

How can i set a default value like "Please make an selection" ?
Anonymous
March 15, 2007
Yes. You need to set the properties on the dropdownlist control to do that.

Select the control
click on Task Panes > Tag Properties
change the AppendDataBoundItem to be True
Click the Smart Panel > Edit Items
click "Add"
type "Please make a selection" for the Text property
Click "OK" That'll do it for you.

Sorry I didn't see these comments in time to respond one at a time...

Paul, you can't use this with ListViews because they don't take parameters in for filtering.
Adam, yeah, you need to code the ParameterBinding by hand, unfortunately. When you follow the above steps, you should have a <parameterbinding location="dropdownlistbox1" .../> tag in your page. You need to change that to this: <parameterbinding location="checkboxlist(checked)" .../> where 'checked' is the property on the control you want to evaluate.
Brian, undortunately, not OOTB in this release. You can do this via Javascript, though, if you search live.com for something like "onchange javascript filter drop down". Sorry I'm not more help on that one.

John, Could you clarify your response to Adam about filtering based on a checkbox? I have not been able to get it to work. When I follow your steps for filtering on the dropdown, the ParameterBinding looks like this: <parameterbinding... location="Control(DropDownList1)" .../> [note the Control(...)]

Do we keep the Control(...) for the checkbox, or does it go away?
Is 'checkboxlist' in your example the id of the checkbox list? The reason I ask is that there is an <asp:checkboxlist> control. I have tried the following variations without success: <parameterbinding... location="chkID(Checked)" .../> <parameterbinding... location="Control(chkID(Checked))" .../> <parameterbinding... location="Checkbox(chkID)" .../> Thanks, Brian

Here I go again providing a solution my own question. I didn't have any luck with the ParameterBinding, so I replaced the WebPartPages:DataFormParameter (that was created when I added the filter) with an asp:ControlParameter. <asp:SqlDataSource... SelectCommand="SELECT * FROM [Table] WHERE [BooleanColumn] = @Condition> <SelectParameters> <asp:ControlParameter Name="Condition" PropertyName="Checked" ControlID="chkTest" DefaultValue="False"/> SelectParameters> </asp:SqlDataSource> Where 'chkTest' is the id of the checkbox on my page, and 'Condition' is the arbitrary name I gave the parameter. Cheers, Brian

Great post - just what I needed. Is there a way to allow for "All Items" to be returned. I have added a default Item to the list and updated the AppendDataBound Items = "true". This gives me a dropdown with choices "All Items" and then my list of choices, but I want the defualt view "All Items" to return all itmes in the list and not filter them, and then for the user to be able to filter the results. Is this possible?

I've used the SPD treeview control with success EXCEPT that, try as I might, I can not figure out how to change the font color and hover color of the linked nodes. I think I've changed every style on every style sheet and changed every NodeStyle parameter the TreeView has, yet the text remains blue. Worse is that the colors do change in Sharepoint Designer but not when I view the font in IE. Can you shed any light on this? Thanks.

(here this is many to many relationship) i tried using your way but it didn't work for me) tell me on how to do this, and remember that product (list2) has lookup field for category( list1) where you can select multiple categories for single product Thanks

Hi, I need an urgent help. I have an aspx page where i have 2 textboxes and 1 drop down list. I have a dataview for which the datasource is from a custom list- Assets. Also the drop down populates values from another list - Asset Type. By default i want the dataview to display all items. Whenever i enter any filter criteria, i want the rows to get filtered. I have created 3 parameters - 2 for text boxes and 1 for drop down. Kindly advice how to proceed, b'coz when i gave % as the default value for these parameters i checked in the DB , when the query was executed the comparison was done - LIKE '%[%]%. I am not able to remove the [] brackets. Please advice Regards, sowmya

I follow the instruction in article, it works fine. But when I open "Data View Properties" and enable "SharePoint List Toolbar", it doesn't work, when you change drop-down list, the Data View always keeps same. So, how to fix this problem?

Hey Chopper and to anyone else who had an issue with the All Items working but the other filter not, try the following:

Smart Panel -> Filter
Click "Add XSLT Filtering..." and then the Edit button
Add the above @CategoryName = $Param1 or $Param1 = '(All)' between the brackets. This will get you to where you were in the step above, but without having to go into code. I did this and had the same problem as you did. Turns out, while you can change the column around, and such, sometimes designer doesn't update the column name. For example, my column was currently named 'Category'. However, originally my column was named Meeting Type. Hence the variable was actually being used by my XSLT was: @Meeting_x0020_Type Now, you can dig through your code to find the correct name, or do the following: Once you are inside that XSLT filter window, the left window that is labeled "Select a field to insert". Browse to your colum you wish to filter by and double click it to insert it. It will show you the current name in the tree menu, but when you insert it it will give you the actual variable name. Hope this helps!

Quick update to my above post. My environment is kind of wonky, so this may not apply to everyone else but: If when you first go into the XSLT edit screen inside the SmartPanel -> Filter window, and you see the following tree structure on your left: dsQueryResponse->Rows->Row but then nothing below on rows do the following: After having checked "Add XSLT Filtering" from the Filter screen, save the aspx page again. Designer doesn't seem to populate the XSLT object browser in the XSLT filter editor screen until the page has been saved with this enabled.

I am wondering how do I filter a data view based on a variable in the page. Currently I have created a Page Layout based on a 'Partner Solution' Site Content Type which has the following Variables (Partner Name(lookup), Solution Name(lookup), description(htmp editor), partner logo(Image Editor), etc...) When I create an instance of this page layout for each partner soltuion I want to be able to use the 'Partner Name (lookup)' from the assocated site content type to filter the data view. I have tried using the control (as each of the columns in the site content type are defined as controls in the page layout) and system variable (cause control didnt work) and used the id as the vlaue but this still does'nt seem to work. I then thought it might be something to do with the postback, wheather it was triggering a event after selection.

Hi everybody! Thanks for your awesome comments – I hope you have some awesome comments for my problem :) I got a Website with a lot of dropdown Lists, which control 3 dataviews and all of them send their information via autopostback to the views. But everytime you choose an option in the dropdown, the postback going to work and send. ( The site actualizes itself. ) So how do I implement a button to postback manually, to save time and work from the server?

Hi everybody This blog is really awesome and has solved most of my queries regarding dropdowns and filtering. But I am just wondering as to how a button can be implemented to solve the above problem of multiple postbacks for multiple dropdowns on page as asked by Christian And on top of that - Would be really great if I can get an answer to this :) How can i get all the filter criterias (like from RadioButtonList1, DropDownList1, DropDownList2, DropDownList3, TextBox etc ) on one page submitted to server on click of lets say 'Search' button ? And results of these search criteria displayed on another ASPX page like 'SearchResults.ASPX' with data in grid form or listview form etc.

I solved my problem! go to the propertiey of your button an you will see "postbackurl" in behaviour. there you simply have to add the url u want to post to and finish! the second question is tsimple: just add the url of your searchresults in the postbackurl from the button.

Hi, great post!! Of course its not working exactly as planned... I have two drop-downs filtering one list - it works fine with this xslt filter: [(@Category = $Param1 or $Param1 = '(All Categories)') and (@Community = $Param2 or $Param2 = '(All Communities)')] HOWEVER, when the page is FIRST loaded, the default results aren't shown - it is blank. I guess I could solve this by loading the page and automatically posting back, but this obviously isn't a good idea. Is there any way to have the results of the filter be shown on the page when it first loads? Thanks!

Okay, I answered my own question, sort of, I have a work around anyways. In addition to what I did as explained above, I also did what the poster said on March 15, 2007 7:38 AM. I appended an item called "-- Please select a value --" but in the VALUE field put in the '(All Communities)'. Seems to work, now when the page loads I still have all of the default values showing up. Dave #2

All of this doesn't work as soon as you use a wss 3.0 masterpage. It works fine in an empty aspx page. With the masterpage the parameter is always set to default and never picks up the actual selected value of the formfield.

Hi Jon, I have reviewed your Demo's six part series. I thought they were very helpful. Thank you. I just started working with SharePoint. I have bought books on sharepoint and browsed ther internet for information. I have some ASP.Net experience. Two things I need to do right a way is design a great looking master page using a team template and the other is to allow internal company users and unkown users to our SharePoint site perhaps using Forms authentication, login/register. I'm not sure if I'm going to use SQL server asp provider. Can you point me in the right direction on these two items?. Any videos on them? Thank you.

Hi John, Can we use a similar approach to filter a datasource inside a DataFormWebPart ? Let me give you the scenario, I've got a department list and a section list on my Site. I want to customize the newform of another list to be able to add Cascading DropDown Functionality for selecting a section ( Department->Section) as follows:

Created a datasource (1) to pickup all departments ( Note that Department Field does not exist in my actual list, only Section Field )
Connected an ASP.Net Dropdownlist to the Datasource (DropDownList1) with AutoPostBack
Create another datasource (2) to pickup the sections - Here I inserted {DepartmentName} as parameter in the CAML Query of the Select Method
Linked the Parameter using ASP:ControlParameter to the DropDownList1.
Added a Sharepoint:DataViewDropDownList, linked to the Section Field of the actual list and also linked to datasource (2) Issues: On opening the form, the list of departments and sections are filled correctly. When selecting another department, postback is performed but the section list does not get refreshed. Is there a fundamental thing I've missed out or this kind of implementation not possible ? Thank you

Hey Darth, Unfortunately, that is not as easy as it sounds. I wrote some jscript to do that once, but it was pretty buggy due to the dynamic nature of the view. In mine, I inserted the checkbox, then converted the Title of a document in the view into an asp:Label control. Then I wrote script that said "for each checkbox, grab the innerText of the next table cell and do something cool". Not great. Someone else who visits here may have a super creative way of doing it, but I haven't really had time to nail one down yet. -John

To John and spdblog about passing a date as a parameter. Unfortunately, it's not that easy. The SPDateTimePicker control returns the date as a US-formatted string, causing the CAML query to fail. I solved this by creating my own date time control that inherited from SPDateTimePicker and added a SelectedValueISO property that returned the date formatted in ISO format.

Hi, For those of you having trouble binding a parameter to an asp TextBox <asp:TextBox runat="server" id="TextBox1" AutoPostBack="true">, I don't think any comments have addressed this, so I am going to post. To bind a parameter to a textbox everyone was trying to use <ParameterBinding Name="Param2" Location="Control(TextBox1,Text)" DefaultValue=""/>, but this will just return the TextMode when trying to use $Param2. Instead set the location to Form(TextBox1) <ParameterBinding Name="Param2" Location="Form(TextBox1)" DefaultValue=""/> Now $Param2 will give the value in TextBox1 !

Not sure a solution was posted to the issue of TextMode being returned from the asp:textbox control when used as a ParameterBinding control. The Location=(Control) is expecting a "Value" property. Putting Location=(Control, Text) you think would fix it and i've seen it work, but not consistently, So I wrote a quickly extension of the textbox class with a Value Property... Works great...

Imports System.Web Imports System.Web.UI Public Class TextBoxWithValue Inherits System.Web.UI.WebControls.TextBox Public ReadOnly Property Value() As String Get Return Me.Text End Get End Property End Class

I apologize for my lack or response here. Yes, it turns out that the Textbox control has an issue because it passes its properties to the page in an arbitrary manner. That is: this fails when the TextMode property is passed in before the Text property. Since the order is arbitrary, an IISRESET will sometimes correct it and then another IISRESET will break it again. I have been working on a way to get this working consistently, but as yet have come up empty. As for validation, I simply put an asp validation control on the page (from the toolbox) and use that. You can't use it with FormField controls, but if you convert the FormField into a TextBox, then you can. HTH -John

Hello, Similar to the problem Inspire had faced, i am also working on the filtering off of a drop down list It does filter correctly but it causes an issue with paging. If there are about 1000 rows. The $Rows parameter holds every single row retrieved from the database. Suppose there are just 50 items matching our filter. Still it returns all the pages with blank items. i dont know how to stop it and sort it so that only the filtered rows are shown. Please help.

I’m trying to filter a list using multiple drop down menus : currency, dimensions and file type. I used the "AutopostBack and controls" method to build the filters. But now I got a problem. what I need is to be able to get results immediately after each filter is chosen, and not have to always choose all 3 filters.(the way it works when using the SharePoint filter web parts) That is, If I choose dollar in currency filter I want to get all the “dollar” items, then if I add file type : jpg I want to see the ones that have dollar and are jpgs. I can’t seem to get it right. If I choose “and” in the data view filter – I don’t get any results till I choose all 3 filters If I choose “or” I end up with all the items that are “Dollar” and also all the “jpgs” instead of items that are “dollar & jpg”. I’m sure there must be a way to get it working.. any ideas ?

I have tried to filter dataformwebpart using a dropdown list as per instructions in this post, however I have not been sucessfull. My dropdown is a lookp from a sql query from our EPR system (ie Project Number). I want to filter my document library to only show documents from the Project Number in the drop down list. Here are the steps:

insert asp.net dropdown, insert datasource (sql query from erp system)
set data field and data text field, autopost back
insert sp doc library as dataview
filter dataview with new param1 from control dropdownlist1 When viewing the page, the document library is not filtered and returns nothing. I've searched everywhere to find how to bind a asp.net dropdown to a sp list of doc library and have had not luck. Thank you for your help. Dan

Any updates on the textbox problem. It is still a problem. When we use the html control like <input id="Something" name="Something"/> then it reads the value, but if you enable paging, and do a post back then value is not retained and it stops working. We can use javascript and onload event in html to have a workaround. Any direct method of making this work Regard Satheesh

This helped me sort out an issue, which was related to this parent > child heirarchy, but that was on the same list. I am using this to show a dropdown where user will select an item, and then in the second dataview I am displaying details of that item. However I noticed that I had to create a copy of the list source and used it to populate dropdown and main list source was used to display item. Till now I am only able to display items when I have choose multiple item view settings for dataview. Is there any way around for showing editable view of that item?

Hi There, What a great post almost got me to where I need to go. How can you create a drop down based on "Choice Items" created within a column of a sharepoint list? Then send filter values to the second and third drop down list. The last drop down list has to "Send to web part connections" Sorry if this is asking too much at once. Thank you,

Thanks for that tip/help! I have been searching for hours and finally came across this site. It worked like a dream and so easy too!....although I did get a little confused about adding a new page ..I wasn't sure if I should add a normal html or aspx. L earned that SPD converts the basic page to a aspx when saved. Also wasn't sure what you meant about the smart panel, and soon realised this was the little right pointed triangle on the control source added to the page. Anyway, Cheers and thank you!

Instead of using ASP.NET control in ParameterBinding use html control and set runat=server and use following code <ParameterBinding Location="Control(txtHtmlTextBox,value)" DefaultValue="" /> This has shown great persistency even if you reset IIS n # time.

I was able to use the dropdownlist to filter a DVWP where the data source is a SharePoint list. However, when I try to use the process on a XML data source (XML File) it does not work. There have been a couple of other responses (ribru on 10/30/2007 and James McDowell on 11/10/2008) that indicate the same thing. Yes - autopostback is set to true on the control. I am displaying the parameter in the DWP to see if the value ever changes but it only displays the first value in the dropdownlist even though the dropdownlist shows the value I selected.

Hi, I'm building a simple document approval workflow using Microsoft Office SharePoint Designer 2007 for a document library. One of the requirements is: When a user initiates the workflow for a document he/she must be able to select one or more approvers. I'm using a column called "Approvers" of type "Lookup" with multi-select option enabled. I have a custom list containing a list of users and use this list to populate values for "Approvers" column. When the user selects one or more approvers, I need to create tasks for each one of them to review the document and approve or reject it. Can someone please let me know how to retrieve the selected values from the multi-select lookup column, in the SharePoint Designer 2007, in the workflow design wizard? Thanks, Kal

Similar to Prakash's post of 1/7/10, I would like to set the selected option to the first option in the list. I've set things up just as directed in the article, but when the page first posts none of the options in the dropdown is selected (I've looked at the HTML via view source). Therefore, the DVWP shows no matching items. If I select the second item from the dropdown, the selected option property is set, and the DVWP populates with the correct data. Everything works as advertised from then on. Is there any way of specifying that the first option from a data source should be selected in the dropdownlist control via SPD?

Just to add to the debate above about getting at the value of a TextBox: Someone mentioned that using Location="Form(TextBox1)" won't return anything. That's because the Form value will be held under the name of the control after ASP.Net has rendered the Textbox into an Input tag. So you need to put in the name (not id) of the input tag. View the page source to find it. So you'll end up with something like: Location="Form(ctl00$PlaceHolderMain$TextBox1)" Of course only use this on a page when you know this control is always going to get named consistently - i.e. the control is staying in the same place on a static page. But if you do move the textbox on the page then remember to check it's new name & modify the parameter accordingly. I've found this to be the simplest way to get textbox working as filters.
