Event handler for OnNodeClick not fired

[Vic]

Hi there,

A RadTreeView control is used as following. Child nodes are populated when the node gets clicked. When debugging the code, I found that the server function "RadTreeView_Catalog_NodeClick" is not fired. So I am not able to populate the treeview on demand.

Expecting help to solve the problem.

Thanks

P.S. The problem is the same event it's not placed in UpdatePanel.
