I'm having an issue with the NodeCollapse not firing on the server side for a RadTreeView.
It works fine for NodeClick and NodeExpand however the server never gets a NodeCollapse event.
The Node expand mode is set to TreeNodeExpandMode.ServerSideCallBack and I'm adding nodes to the tree on the NodeExpand event which is working fine.
I tried setting the Node.Postback to true but that doesn't seem to have made any difference.
Is there something obvious I'm missing?

Hello Jose,

The OnNodeCollapse event won't fire for ExpandMode different form ServerSide. The reason is that in your case for ServerSideCallBack an asynchronous callback is fired.

Please take a look at this help topic for the different ExpandMode values.

All the best,
