There is no property called NextNode or PrevNode or Index for a treenode. You should loop through the node. For eg: TreeNode tn = new TreeNode(); for (int i=0; i<=tn.ChildNodes.Count - 1; i++) { // Write your code here. // Index is present for ChildNodes. } Hope this helps. Success is the good fortune that comes from aspiration, desperation, perspiration and inspiration.

Or you could put ASP:Panel inside another update Panel and set it's update mode to Always, But I think javascript will still be better
