Hi Kevin,

Try the following code snippet to get the child nodes on the server side.

CS:

protected void RadTreeView1_PreRender(object sender, EventArgs e)
    {
        foreach(RadTreeNode parentnode in RadTreeView1.Nodes)
        {
            if (parentnode.Expanded)
            {
                RadTreeNode ChildNode1 = (RadTreeNode)parentnode.Nodes[0];
                RadTreeNode ChildNode2 = (RadTreeNode)parentnode.Nodes[1];
            }
        }
    }

Regards
Shinu.

Hi Kevin,

You can try the following approach to see whether a clicked node has child nodes or not.

CS:

protected void RadTreeView1_NodeClick(object sender, RadTreeNodeEventArgs e)
    {
        if (e.Node.Nodes.Count == 0)
        {
            Response.Write("THIS NODE HAS NO CHILDREN");
        }
        else
        {
            Response.Write("THIS NODE HAS  CHILDREN");
        }
    }

Go through the following forum discussion which explains more on this regard.
Node has child or not?

Thanks
