Hi there, You need to reinsert the script to cause the page to post back since it is overwritten at the client side by your sample script:
Me.TreeView1.Attributes.Add("oncheck", clickHandler1 & " if (this.clickedNodeIndex != null)
this.queueEvent('oncheck', this.clickedNodeIndex)")Also, you need to make sure that the
AutoPostBackproperty is set totrue.
