Can you tell me why?
I have attached my small VS2008 project where the problem occurs. I had to change the extension from .zip attachment to .jpg, so detach it and rename to .zip before extracting it.
Thanks.

The treeview is not updated after ajax hence adding the node seems like it has no effect. Please add the treeview in the update panel so it is updated after ajax request.

I use VS 2008. Telerik tools are in the toolbox. I notice that OnContextMenuItemClick is not in the TreeView property.
Does that mean something?

Per the advice of support, I added the entire treeview to the update panel, and it worked for me.
Not sure what you mean about OnContextMenuItemClick. I'm using it in my example.

To understand more about this, I added the alert() in the onClientContextMenuShowing to show the property values. First, I get the menu object:
treeNode.get_contextMenu()
It shows that enable state is "undefined" and visible is false. (it displays correctly if NOT in popup).
So I add these two lines:
menu.set_enabled();
menu.show(evt);
It still does not work.
What I don't understand is that same code works in the non-popup scenario.
I need help.
