Question

I’m trying to refresh update panel via Javascript:

  __doPostBack("<%=upMyPanel.ClientID %>", "");

But somehow its controls are all empty. On other hand they are all filled when I click any trigger control.
How can I fix this?
thanx.

AFAIK the UpdatePanel doesn’t really postback, so your postback should be using a control that is registered for postbacks (i.e. the trigger control you speak of).

__doPostBack("<%=btnMyTrigger.ClientID %>", "");
