ASPxSiteMapDataSource.StartingNodeUrl Property

Gets or sets a node in the site map that the data source then uses as a reference point to retrieve nodes from a hierarchical site map.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v24.2.dll

Declaration

C#

public override string StartingNodeUrl { get; set; }

VB.NET

Public Overrides Property StartingNodeUrl As String

Property Value

Type	Description
String	The URL of a node in the site map. The ASPxSiteMapDataSource retrieves the identified SiteMapNode and any child nodes from the site map.

Remarks

If the ASPxSiteMapDataSource.ShowStartingNode property is set to true, the StartingNodeUrl property can be used to specify the URL of the starting node which is the root node of the site map hierarchy.

Note that this property is not in effect if the ASPxSiteMapDataSource.ShowStartingNode property is set to false.

Example

This example illustrates how to share the same SiteMap between ASPxMenu and ASPxSiteMapControl placed to show information from different SiteMap node levels. Here are steps you need to execute:

Default.aspx (VB.NET)

<dx:ASPxSiteMapDataSource ID="menuSiteMapDataSource" runat="server" SiteMapProvider="MenuSiteMapProvider" />

<dx:ASPxMenu ID="ASPxMenu1" runat="server" DataSourceID="menuSiteMapDataSource" EnableViewState="false">
    <SubMenuTemplate>
        <dx:ASPxSiteMapControl EnableViewState="False" ID="ASPxSiteMapControl1" runat="server"
                DataSource=<%#GetDataSource()%> OnDataBinding="ASPxSiteMapControl1_DataBinding">
            <Columns>
                <dx:SiteMapColumn />
                <dx:SiteMapColumn />
            </Columns>
        </dx:ASPxSiteMapControl>
    </SubMenuTemplate>
</dx:ASPxMenu>

Default.aspx.cs

public object GetDataSource() {
    ASPxSiteMapDataSource ds = new ASPxSiteMapDataSource();
    ds.SiteMapProvider = menuSiteMapDataSource.SiteMapProvider;
    return ds;
}
protected void ASPxSiteMapControl1_DataBinding(object sender, EventArgs e) {
    ASPxSiteMapControl sitemapControl = sender as ASPxSiteMapControl;
    DevExpress.Web.ASPxMenu.MenuItemTemplateContainer container = sitemapControl.NamingContainer as DevExpress.Web.ASPxMenu.MenuItemTemplateContainer;
    (sitemapControl.DataSource as ASPxSiteMapDataSource).StartingNodeUrl = container.Item.NavigateUrl;
}

Default.aspx.vb

Public Function GetDataSource() As Object
    Dim ds As New ASPxSiteMapDataSource()
    ds.SiteMapProvider = menuSiteMapDataSource.SiteMapProvider
    Return ds
End Function
Protected Sub ASPxSiteMapControl1_DataBinding(ByVal sender As Object, ByVal e As EventArgs)
    Dim sitemapControl As ASPxSiteMapControl = 
        TryCast(sender, ASPxSiteMapControl)
    Dim container As DevExpress.Web.ASPxMenu.MenuItemTemplateContainer = 
        TryCast(sitemapControl.NamingContainer, DevExpress.Web.ASPxMenu.MenuItemTemplateContainer)
    TryCast(sitemapControl.DataSource, ASPxSiteMapDataSource).StartingNodeUrl = container.Item.NavigateUrl
End Sub
