Update Gridview on treeview node checked
<p>I need to update or filter the records in gridview, when I check a node in treeview <strong>without postback.</strong>
I tried placing the gridview in update panel and registered ASYNCPOSTBACKTRIGGER for treeviews NODECHECKCHANGED event, but still the postback occurs.</p>

<p>How can I solve this or any other approach? please help</p>
