Hi Eddie and Karthik,

You can subscribe to the OnNodeExpand server-side event of the RadTreeView. In my example I use Load-On-Demand technique and add 5 nodes on expanding of the root node:

protected void RadTreeView1_NodeExpand(object sender, RadTreeNodeEventArgs e)
    {
        RadTreeNode node = e.Node as RadTreeNode;
        for (int i = 0; i < 5; i++)
        {
            node.Nodes.Add(new RadTreeNode("Child Node" + i));
        }
    }

Find the full code in the attached .zip file.

Please let me know if you have further questions.

All the best,
