For a CMS, I use the treeview control with CSS friendly adapter binded with the sitemap :

  <asp:TreeView DataSourceID="SiteMapDataSource1" ID="EntertainmentTreeView" runat="server" OnSelectedNodeChanged="OnClick" OnAdaptedSelectedNodeChanged="OnClick" >
   <DataBindings>
    <asp:TreeNodeBinding DataMember="SiteMapNode" TextField="Title" ValueField="url" />
   </DataBindings>
  </asp:TreeView>

    <asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" />

But when I click on a node, the treeview does not respond, doesn't send event. If I replace the ValueField "url" by for example "title", the event is ok.

How can I force the treeview to send Event with ValueField="url" ?

You can see a sample at www.almageste.info/preuve2.zip.

Thanks for your help !

Associating your SiteMap to a TreeView is StraightForward.

Make sure your Web.SiteMap is in correct shape,like this:-

<?xml version="1.0" encoding="ISO-8859-1" ?>
<siteMap>
  <siteMapNode title="Home" url="/aspnet/w3home.aspx">
    <siteMapNode title="Services" url="/aspnet/w3services.aspx">
      <siteMapNode title="Training" url="/aspnet/w3training.aspx"/>
      <siteMapNode title="Support" url="/aspnet/w3support.aspx"/>
    </siteMapNode>
  </siteMapNode>
</siteMap>

Then use SiteMapDataSource

 <asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" /> 

//and in ur Aspx page add a tree view like this:-

<asp:TreeView runat="server" DataSourceId="SiteMapDataSource1" />

Alse refer this:-

I hope this helps..

Enjoy...

I also do this and my SiteMapDataSource is OK.

The page code is :

<%@ Page Language="C#" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
public void OnClick(Object sender, EventArgs e)
{
  MessageLabel.Text = "You selected " + EntertainmentTreeView.SelectedNode.Text + ".";
}
</script>
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<asp:TreeView DataSourceID="SiteMapDataSource1" ID="EntertainmentTreeView" runat="server" OnSelectedNodeChanged="OnClick" OnAdaptedSelectedNodeChanged="OnClick">
  <DataBindings>
   <asp:TreeNodeBinding DataMember="SiteMapNode" TextField="Title" NavigateUrlField="url" SelectAction="Select" />
  </DataBindings>
</asp:TreeView>
<asp:Label ID="MessageLabel" runat="server" />
<asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" />
</form>
</body>
</html>

And the Sitemapdatasource is:

<?xml version="1.0" encoding="utf-8" ?>

</siteMapNode>

</siteMap>
