[Solved] call an AJAX request from clicking on node

[Jay]

I have a RadTreeView which is using TreeNodeExpandMode.ServerSideCallBack.

When a node is clicked, I want to expand the node (if not already), and send an AJAX event to the server. I captured the client OnClientNodeClicking and do an AJAX:

function OnClientNodeClicking(sender, args)
{
 var node = args.get_node();
 // If the tree is not expanded, then expand it now
 if (node.get_expanded() == false)
 {
  node.toggle();
 }
 else
 {
  var ajaxManager = $find("<%= RadAjaxManager1.ClientID %>");
  ajaxManager.ajaxRequest("test");
 }
}


but I do not know how to tell the tree control to expand (toggle) the tree node, AND send up a AJAX request. It seems to "step on" the AJAX request that actually fills the dropdown if I do the ajaxRequest AND call node.toggle.

Any idea how I can expand the node AND fire an AJAX event?

Thanks

Hi Jay,

I am not sure whether I can correctly understand your goal.

What about hooking on the OnClientNodeExpanding  event instead of the OnClientNodeClicking. However, it is not a good approach using two ajax mechanisms this way as they might interfere with each other. Nevertheless, I suggest you try wiring the OnClientNodeExpanding event and let us know how this goes.
