asp.net disabling listbox on postback
<p>I have a asp.net listbox. A master-detail view. When the selectionchanges on the listbox, controls on an update panel update. All working fine. Now if the user arrows through the listbox selections I get like a million postbacks. Ideally (for UX) it would be great to cancel the previous postback. But what I tried was on the PageRequestManager.add_initializeRequest: disable the listbox with jquery so the user cannot make another selection. Then on add_endRequest enable the listbox. The boss does not like the disabled look for a couple of seconds.</p>

<p>Can someone think of a better way for me to handle this? I tried changing the color while disabled but could not find a way.</p>
