Hello Sindu,

You can add a TreeList in the NodeTemplate of the TreeView as shown below.
aspx:

<telerik:RadTreeView ID="tree" runat="server">
  <Nodes>
     <telerik:RadTreeNode Text="Expand" Expanded="true" >
        <Nodes>
           <telerik:RadTreeNode Text="show" Expanded="true">
               <NodeTemplate>
                 <telerik:RadTreeList  ID="RadTreeList1" runat="server" AutoGenerateColumns="true" DataSourceID="SqlDataSource1" ParentDataKeyNames="ReportsTo" DataKeyNames="EmployeeID">
                 </telerik:RadTreeList>
               </NodeTemplate>
          </telerik:RadTreeNode>
       </Nodes>
    </telerik:RadTreeNode>
  </Nodes>
</telerik:RadTreeView>

Hi Shinu,

Thanks you verymuch for your help.
How can I access RadTreelist from the RadTreeview ?

I have tried the code 
RadTreeNode node = tree.Nodes[0];

RadTreeList List1 = (RadTreeList)node.FindControl("RadTreeList1");

But then I get ,object reference not set to an instance of the object error.

so what code should I used for accessing the RadTreelist inside the RadTreeview?

Hello Sindu,

Try the following code snippet to access RadTreeList
C#:

protected void RadTreeView1_NodeClick(object sender, RadTreeNodeEventArgs e)
{
  foreach (RadTreeNode node in RadTreeView1.GetAllNodes())
  {
     RadTreeList list =(RadTreeList)node.FindControl("RadTreeList1");
  }
}

Thanks,
Shinu.

Another problem arise .

I have put the RadTreelist inside the RadTreeview .Then the content of the RadTreelist is not  wrapped.If RadTreeList is inside RadTreeview ,then wrapping is not working ...How can we wrap the content and heading?


Thanks ,
