Appreciate your reply, Yudi.

But in my case, i need to get the checked nodes at server side because after i get checked nodes, i need to perform some database query execution.

Pls advise.

Thanks!

I tested with simpler scenario:

I have a page with 1 WebTreeView and 1 WebButton.

During page load, i'll retrieve data from sql and populate the data into WebTreeView.

In the WebButton (AutoPostBack=True and PostBackMode=FullPostBack) clicked event, i use WebTreeView.CheckedNodes to get the nodes checked by user.

When i checked few nodes and click the WebButton, the CheckedNodes function return no nodes checked.

It seems like we are not able to get checked nodes if the WebTreeView is populated from sql instead of xml?

Pls advise! Thanks!
