Hi Santhosh,

Try the following code snippet for adding RadGrid to RadTreeView as NodeTemplate. In this example I tried to pass the DataSourceID as parameter when creating the template node.

CS:

protected override void OnInit(EventArgs e)
{
    RadTreeView1.NodeTemplate = new RadGridTemplate();
    base.OnInit(e);
}
protected void Page_Load(object sender, EventArgs e)
{
    if (!Page.IsPostBack)
    {
        RadTreeView1.FindNodeByText("Node1").Nodes.Add(new RadTreeNode("SqlDataSource1"));
    }
    RadTreeView1.DataBind();
}
class RadGridTemplate : ITemplate
{
    public void InstantiateIn(Control container)
    {
        RadGrid RadGrid1 = new RadGrid();
        RadGrid1.DataBinding += new EventHandler(RadGrid_DataBinding);
        container.Controls.Add(RadGrid1);
    }
    private void RadGrid_DataBinding(object sender, EventArgs e)
    {
        RadGrid target = (RadGrid)sender;
        RadTreeNode node = (RadTreeNode)target.BindingContainer;
        string source = (string)DataBinder.Eval(node, "Text");
        target.DataSourceID = source;
    }
}

ASPX:

<telerik:RadTreeView ID="RadTreeView1" Runat="server">
<Nodes>
      <telerik:RadTreeNode Text="Node1"></telerik:RadTreeNode>
</Nodes>
</telerik:RadTreeView>

Thanks,
Shinu.

Hi Shinu:
Does this work when the data source is relational data?  I have 5 relational tables nested one to the other... I followed the telerik relational data training video exactly - and it works wonderfully, but it would be really good to put a grid in at each node level...
Thanks,
