var o = window.event.srcElement;
if (o.tagName == 'INPUT' && o.type == 'checkbox' &&
o.name != null && o.name.indexOf('CheckBox') > -1)
<asp:TreeView onclick="postbackOnCheck()" ID="treeContent"
runat="server"> ... And so on ... </TreeView> This way I get full postback each time the user checks\unchecks the checkbox.
But now I want to modify this code in order to make use of AJAX: I don't want the FULL postback, but I only want the tree itself to be updated. Of course, I've started by placing it inside the UpdatePanel. But what now? Can somebody help me with this issue?
No, that won't work for me... There has to be a postback, because my tree is dynamic, it is filled in "lazy" mode on server-side. So I can't check the checkboxes on the client-side - they may not exist there at all...
Do you know how can I update the update panel on the client-side? I know that there is some way using PageRequestManager... But I can't find how exactly this works. This is the only thing I need to solve the issue now...

That is exactly what I am trying to show you. AJAX sends data to the server and then sends the data back to the client-side. Did you even browse into the link I posted? There are more pages there to browse. Read the whole AJAX section.
