This topic describes creating a SharePoint 2010 client object.

Applies to: SharePoint Foundation 2010

If a client object can be created, such as a List object (JavaScript: List), its corresponding client object collection, such as ListCollection (JavaScript: ListCollection), has an Add method that accepts a ClientObjectCreationInformation object, for example, ListCreationInformation (JavaScript: ListCreationInformation), which contains all the information required to create the new object.

The following example uses WebCreationInformation (JavaScript: WebCreationInformation) with the Add(WebCreationInformation) method (JavaScript: add(parameters)) to create a child Web site under a specified Web site .

ClientContext clientContext = new ClientContext("http://MyServer/sites/MySiteCollection/MyWebSite");
WebCollection collWeb = clientContext.Web.Webs;

WebCreationInformation webCreationInfo = new WebCreationInformation();
webCreationInfo.Title = "My New Web Site";
webCreationInfo.Description = "Description of new Web site...";
webCreationInfo.Language = 1033;
webCreationInfo.Url = "MyNewWebSite";
webCreationInfo.UseSamePermissionsAsParentSite = true;
webCreationInfo.WebTemplate = "STS#0";

Web oNewWebsite = collWeb.Add(webCreationInfo);
clientContext.ExecuteQuery();

Dim clientContext As New ClientContext("http://MyServer/sites/MySiteCollection/MyWebSite")
Dim collWeb As WebCollection = clientContext.Web.Webs
         
Dim webCreationInfo As New WebCreationInformation()
webCreationInfo.Title = "My New Web Site"
webCreationInfo.Description = "Description of new Web site..."
webCreationInfo.Language = 1033
webCreationInfo.Url = "MyNewWebSite"
webCreationInfo.UseSamePermissionsAsParentSite = True
webCreationInfo.WebTemplate = "STS#0"
         
Dim oNewWebsite As Web = collWeb.Add(webCreationInfo)
clientContext.ExecuteQuery()

function createWebsite() {

    var clientContext = new SP.ClientContext('http://MyServer/sites/MySiteCollection/MyWebSite');
    var collWeb = clientContext.get_web().get_webs();

    var webCreationInfo = new SP.WebCreationInformation();
    webCreationInfo.set_title('My New Web Site');
    webCreationInfo.set_description('Description of new Web site...');
    webCreationInfo.set_language(1033);
    webCreationInfo.set_url('MyNewWebSite');
    webCreationInfo.set_useSamePermissionsAsParentSite(true);
    webCreationInfo.set_webTemplate('STS#0');

    var oNewWebsite = collWeb.add(webCreationInfo);


    clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));
}

function onQuerySucceeded() {
    alert("Created Web site.");
}

function onQueryFailed(sender, args) {
    alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
}

In the previous example, the Add(WebCreationInformation) method (JavaScript: add(parameters)) creates a Web site immediately in the client object collection, without waiting for subsequent collection data retrieval or for a call to ExecuteQuery() or ExecuteQueryAsync(ClientRequestSucceededEventHandler, ClientRequestFailedEventHandler) (JavaScript: executeQueryAsync(succeededCallback, failedCallback)).

You can use a ClientObjectCreationInformation object to create numerous objects. Creating a navigation node, for example, also involves using a ClientObjectCreationInformation object. The following example defines a navigation node by means of a NavigationNodeCreationInformation object (JavaScript: NavigationNodeCreationInformation), and uses this object to add a link within the Quick Launch area of the specified Web site. The example adds a link to a list on another Web site as the second child node under the top-level Lists node.

ClientContext clientContext = new ClientContext("http://MyServer/sites/MySiteCollection/MyWebSite");

NavigationNodeCollection collNavNode = clientContext.Web.Navigation.QuickLaunch;

clientContext.Load(collNavNode);
clientContext.ExecuteQuery();

NavigationNodeCollection collChildNavNode = collNavNode[1].Children;

clientContext.Load(collChildNavNode);
clientContext.ExecuteQuery();

NavigationNodeCreationInformation navNodeCreationInfo = new NavigationNodeCreationInformation();

navNodeCreationInfo.PreviousNode = collChildNavNode[0];
navNodeCreationInfo.Title = "My Navigation Node";
navNodeCreationInfo.Url = "http://MyServer/sites/MySiteCollection/MyTargetListWebSite/Lists/MyTargetList/AllItems.aspx";

collChildNavNode.Add(navNodeCreationInfo);

clientContext.ExecuteQuery();

Dim clientContext As New ClientContext("http://MyServer/sites/MySiteCollection/MyWebSite")
         
Dim collNavNode As NavigationNodeCollection = clientContext.Web.Navigation.QuickLaunch
         
clientContext.Load(collNavNode)
clientContext.ExecuteQuery()
         
Dim collChildNavNode As NavigationNodeCollection = collNavNode(1).Children
         
clientContext.Load(collChildNavNode)
clientContext.ExecuteQuery()
         
Dim navNodeCreationInfo As New NavigationNodeCreationInformation()
         
navNodeCreationInfo.PreviousNode = collChildNavNode(0)
navNodeCreationInfo.Title = "My Navigation Node"
navNodeCreationInfo.Url = "http://MyServer/sites/MySiteCollection/MyTargetListWebSite/Lists/MyTargetList/AllItems.aspx"
         
collChildNavNode.Add(navNodeCreationInfo)
         
clientContext.ExecuteQuery()

function getNavNodes() {
    this.clientContext = new SP.ClientContext('/sites/MySiteCollection/MyWebSite');
    this.collNavNode = clientContext.get_web().get_navigation().get_quickLaunch();

    clientContext.load(collNavNode);
    clientContext.executeQueryAsync(Function.createDelegate(this, this.getChildNavNodes), Function.createDelegate(this, this.onQueryFailed));
}

function getChildNavNodes() {

    this.collChildNavNode = collNavNode.get_item(1).get_children();
    clientContext.load(collChildNavNode);
    clientContext.executeQueryAsync(Function.createDelegate(this, this.createNavNode), Function.createDelegate(this, this.onQueryFailed));
}

function createNavNode() {

    var navNodeCreationInfo = new SP.NavigationNodeCreationInformation();
    navNodeCreationInfo.set_previousNode(collChildNavNode.get_item(0));
    navNodeCreationInfo.set_title('My Navigation ECMA Node');
    navNodeCreationInfo.set_url('http://MyServer/sites/MySiteCollection/MyTargetListWebSite/Lists/MyTargetList/AllItems.aspx');

    collChildNavNode.add(navNodeCreationInfo);

    clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));
}

function onQuerySucceeded() {

    alert("Created navigation node.");
}

function onQueryFailed(sender, args) {
    alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
}

The previous example creates a link to another Web site within a site collection. To create an external link to a location outside the site collection, set the IsExternal property (JavaScript: IsExternal) of the NavigationNodeCreationInformation object (JavaScript: NavigationNodeCreationInformation) to true before you call the Add(NavigationNodeCreationInformation) method (JavaScript: add(parameters)).
