OnClick not fired with Entity/LINQ DataSource

[Lone]

Hey Telerik

I have big problems using my Entity datasource with my TreeView.
Everything is shown just fine, but can't get OnNodeClick event to fire.

Please advise !!

Thanks
Jan

<telerik:RadTreeView runat="Server" ID="BookGroupTreeView" DataFieldID="Hierarchy_id"
    DataFieldParentID="Parent_Hierarchy_id" DataTextField="Name" DataValueField="Hierarchy_id"
    Skin="Vista" EnableTheming="True" RegisterWithScriptManager="true" OnNodeClick="BookGroupTreeView_NodeClick">
</telerik:RadTreeView>

protected void Page_Load(object sender, EventArgs e)
 {
     List<DB.Hierarchy> bookHierarchy = new List<DB.Hierarchy>();
     bookHierarchy = DB.HierarchyService.HierarchyFullListFromParentPath("Root");

     BookGroupTreeView.DataSource = bookHierarchy;
     BookGroupTreeView.DataBind();
     BookGroupTreeView.ExpandAllNodes();
 }

Hi Jan Hjørdie,

Here is a sample page with two treeview controls - one linked to an entity datasource, the other one linked to a linq datasource. I attached an event handler on both trees and it behaves as it should - the event is fired.

Best wishes,

Hey Kate
Thanks for your example.
My data is not presentet the way you suggest. I have my data layer in a seperate project. My DB project, where I ex. have a Hierachy Service, that return a List<Hierachy>.

So what should I do then ? Do I need the LinqDataSource ? I just thought setting the treeview datasource to bookHierachy was enough ?
My treeview is rendered just fine, it's just my OnNodeClick event that don't fire ?

 <asp:LinqDataSource ID="LinqDataSource1" runat="server" EntityTypeName="" ContextTypeName="DataClassesDataContext"

           TableName="Links">

 </asp:LinqDataSource>

List<DB.Hierarchy> bookHierarchy = new List<DB.Hierarchy>();

bookHierarchy = DB.HierarchyService.HierarchyFullListFromParentPath("Emner");

 
Thanks
Jan
