Pop up not working on second click of a tree view node

[Sneha Shetty]

I am using a TreeView which have few nodes that generate a popup panel. For this, I use the SelectedNodeChanged event and
then add the relevant modalpopupextender to the page.

This seems to work fine, but if the user clicks on the same node twice, the event doesn't fire a second time. I assume this is by design as the Node Selection hasn't changed, but i tried clearing the selection by writing the below code in the close event of a button whcih is present in the panel.

 
TreeView1.SelectedNode.Checked=false
 

But while debugging I am unable to reache that code.

Can anyone suggest where can the code be best reachable

The pop-up...is it shown using JavaScript?
Are you using UpdatePanels?

I'm not sure what you're talking about with regards to the code you've posted. Is it executed in the Button's Click event? If so, did you click the button?
