I want to update a RadAjaxPanel, when I have been clicking a RadMenuItem of a RadTreeView.
That treeview is not inside the RadAjaxPanel but on the same page as it.
If I add a OnNodeClick handler to the RadTreeView and add a event handler in code behind, then clicking a RadMenuItem of the treeview will cause a postback and the whole page will reload.
Instead, I want the RadAjaxPanel to reload so I can bind a grid in it.
How can I do that? I will not move the treeview inside the ajax panel.
