How to fill lable or textbox (.net2.0 + AJAX )

This should work fine but the event handling (e.g. EventClickHandling) must be set to PostBack.

You can' t reach other controls using CallBack events (UpdatePanel doesn't help in this case).

Thanks for the reply.

Last question; Is there any way that I can raise an event with post back and have javascript simultaneously?

Yes, it's possible. You have to switch to JavaScript handling and execute the PostBack from your code.

EventDelete example:

EventDeleteHandling="JavaScript" 
EventDeleteJavaScript="delete(e)"

<script type='text/javascript'>
function delete(e) {
  // your code here
  dpc1.eventDeletePostBack(e);
}
</script>

Great, thankx; I did it.
