How to: Work with User Custom Actions

Applies to: SharePoint Foundation 2010

Available in SharePoint Online

You can use the client object model to add custom actions to the user interface. The UserCustomActions property returns the collection of custom actions for a site collection, Web site, or list. To create a custom action in one of these collections, call the Add() method of the UserCustomActionCollection class. Set properties for the new action on the returned UserCustomAction object, and then call the Update() method before you execute the query by calling the ExecuteQuery() or ExecuteQueryAsync(ClientRequestSucceededEventHandler, ClientRequestFailedEventHandler) methods. The placement of a user custom action can be determined by its namespace location, custom action group, and sequence in relation to other user custom actions. For a table that lists possible values for custom action locations and groups, see Default Custom Action Locations and IDs.

Adding a user custom action for list items

The following example adds a user custom action to the drop-down menu that is displayed for list items. To place the new action on the menu, the Location property specifies EditControlBlock, Sequence specifies an order of placement in relation to other user custom actions, and Url specifies an absolute path to a page that defines the action. The example assumes the existence of a .aspx file that is located in %ProgramFiles%\Common Files\Microsoft Shared\web server extensions\14\TEMPLATE\LAYOUTS.

using System;
using Microsoft.SharePoint.Client;

namespace Microsoft.SDK.SharePointServices.Samples
{
    class CreateUserCustomActionList
    {
        static void Main()
        {
            string urlWebsite = "http://MyServer/sites/MySiteCollection";
            ClientContext clientContext = new ClientContext(urlWebsite);
            Web oWebsite = clientContext.Web;

            List oList = oWebsite.Lists.GetByTitle("My List");
            UserCustomActionCollection collUserCustomAction = oList.UserCustomActions;

            UserCustomAction oUserCustomAction = collUserCustomAction.Add();
            oUserCustomAction.Location = "EditControlBlock";
            oUserCustomAction.Sequence = 100;
            oUserCustomAction.Title = "My First User Custom Action";
            oUserCustomAction.Url = urlWebsite + @"/_layouts/MyPage.aspx";
            oUserCustomAction.Update();

            clientContext.Load(oList,
                list => list.UserCustomActions);

            clientContext.ExecuteQuery();
        }
    }
}
Imports System
Imports Microsoft.SharePoint.Client

Namespace Microsoft.SDK.SharePointServices.Samples
    Class CreateUserCustomActionList

        Shared Sub Main()
            Dim siteUrl As String = "http://MyServer/sites/MySiteCollection"
            Dim clientContext As New ClientContext(siteUrl)

            Dim oWebsite As Web = clientContext.Web

            Dim oList As List = oWebsite.Lists.GetByTitle("My List")
            Dim collUserCustomAction As UserCustomActionCollection = oList.UserCustomActions

            Dim oUserCustomAction As UserCustomAction = collUserCustomAction.Add()
            oUserCustomAction.Location = "EditControlBlock"
            oUserCustomAction.Sequence = 100
            oUserCustomAction.Title = "My First User Custom Action"
            oUserCustomAction.Url = siteUrl + "/_layouts/MyPage.aspx"
            oUserCustomAction.Update()

            clientContext.Load(oList, Function(list) list.UserCustomActions)

            clientContext.ExecuteQuery()

        End Sub
    End Class
End Namespace

Modifying a user custom action

The following example retrieves an action from the collection of user custom actions for the drop-down menu of items in a list, and updates the custom action to include an icon that represents the action on the menu. The example assumes the existence of an icon image file that is located in %ProgramFiles%\Common Files\Microsoft Shared\web server extensions\14\TEMPLATE\IMAGES.

using System;
using Microsoft.SharePoint.Client;

namespace Microsoft.SDK.SharePointServices.Samples
{
    class ModifyUserCustomAction
    {
        static void Main()
        {
            string urlWebsite = "http://MyServer/sites/SiteCollection";
            ClientContext clientContext = new ClientContext(urlWebsite);
            Web oWebsite = clientContext.Web;

            List oList = oWebsite.Lists.GetByTitle("My List");
            UserCustomActionCollection collUserCustomAction = oList.UserCustomActions;

            clientContext.Load(collUserCustomAction,
                userCustomActions => userCustomActions.Include(
                    userCustomAction => userCustomAction.Title));

            clientContext.ExecuteQuery();

            foreach (UserCustomAction oUserCustomAction in collUserCustomAction)
            {
                if (oUserCustomAction.Title == "My First User Custom Action")
                {
                    oUserCustomAction.ImageUrl = "http://MyServer/_layouts/images/MyIcon.png";
                    oUserCustomAction.Update();

                    clientContext.ExecuteQuery();
                }
            }
        }
    }
}
Imports System
Imports Microsoft.SharePoint.Client

Namespace Microsoft.SDK.SharePointServices.Samples
    Class ModifyUserCustomAction

        Shared Sub Main()
            Dim siteUrl As String = "http://MyServer/sites/MySiteCollection"
            Dim clientContext As New ClientContext(siteUrl)
            Dim oWebsite As Web = clientContext.Web

            Dim oList As List = oWebsite.Lists.GetByTitle("My List")
            Dim collUserCustomAction As UserCustomActionCollection = oList.UserCustomActions

            clientContext.Load(collUserCustomAction, _
                               Function(userCustomActions) userCustomActions.Include( _
                                   Function(userCustomAction) userCustomAction.Title))

            clientContext.ExecuteQuery()

            Dim oUserCustomAction As UserCustomAction
            For Each oUserCustomAction In collUserCustomAction
                If oUserCustomAction.Title = "My First User Custom Action" Then
                    oUserCustomAction.ImageUrl = "http://MyServer/_layouts/images/MyIcon.png"
                    oUserCustomAction.Update()

                    clientContext.ExecuteQuery()
                End If
            Next oUserCustomAction

        End Sub
    End Class
End Namespace

Adding a user custom action to the site actions of a Web site

Creating a user custom action on the Site Actions menu of a Web site is similar to creating an action for list items: You call the Add() method, set properties for the action, and then call Update(). The following example specifies Microsoft.SharePoint.StandardMenu for Location, and SiteActions for Group, to place the new action on the Site Actions menu. The value of Sequence specifies 101 so that the action will appear below an action whose sequence number is 100. The example assumes the existence of a .aspx file that is located in %ProgramFiles%\Common Files\Microsoft Shared\web server extensions\14\TEMPLATE\LAYOUTS.

using System;
using Microsoft.SharePoint.Client;

namespace Microsoft.SDK.SharePointServices.Samples
{
    class CreateUserCustomActionSite
    {
        static void Main()
        {
            string urlWebsite = "http://MyServer/sites/MySiteCollection";
            ClientContext clientContext = new ClientContext(urlWebsite);

            Web oWebsite = clientContext.Web;
            UserCustomActionCollection collUserCustomAction = oWebsite.UserCustomActions;

            UserCustomAction oUserCustomAction = collUserCustomAction.Add();

            oUserCustomAction.Location = "Microsoft.SharePoint.StandardMenu";
            oUserCustomAction.Group = "SiteActions";
            oUserCustomAction.Sequence = 101;
            oUserCustomAction.Title = "Website User Custom Action";
            oUserCustomAction.Description = "This description appears on the Site Actions menu.";
            oUserCustomAction.Url = urlWebsite + @"/_layouts/MyPage.aspx";

            oUserCustomAction.Update();

            clientContext.Load(oWebsite,
                webSite => webSite.UserCustomActions);

            clientContext.ExecuteQuery();
        }
    }
}
Imports System
Imports Microsoft.SharePoint.Client

Namespace Microsoft.SDK.SharePointServices.Samples
    Class ModifyUserCustomAction

        Shared Sub Main()
            Dim siteUrl As String = "http://MyServer/sites/MySiteCollection"
            Dim clientContext As New ClientContext(siteUrl)
            Dim oWebsite As Web = clientContext.Web

            Dim collUserCustomAction As UserCustomActionCollection = oWebsite.UserCustomActions

            Dim oUserCustomAction As UserCustomAction = collUserCustomAction.Add()

            oUserCustomAction.Location = "Microsoft.SharePoint.StandardMenu"
            oUserCustomAction.Group = "SiteActions"
            oUserCustomAction.Sequence = 101
            oUserCustomAction.Title = "Website User Custom Action"
            oUserCustomAction.Description = "This description appears on the Site Actions menu."
            oUserCustomAction.Url = siteUrl + "/_layouts/MyPage.aspx"

            oUserCustomAction.Update()

            clientContext.Load(oWebsite, Function(webSite) webSite.UserCustomActions)

            clientContext.ExecuteQuery()

        End Sub
    End Class
End Namespace
