TreeView checkboxes AutoPostBack with AJAX

[Dmitry Perets]

Hello,

There is a known problem with TreeView checkboxes in ASP.NET: they
can't do AutoPostBack. So I've solved this problem like this:

<script language="javascript" type="text/javascript">

function postbackOnCheck()
{
var o = window.event.srcElement;
if (o.tagName == 'INPUT' && o.type == 'checkbox' &&
o.name != null && o.name.indexOf('CheckBox') -1)
{
__doPostBack("","");
}
}

</script>

<asp:TreeView onclick="postbackOnCheck()" ID="treeContent"
runat="server"... And so on ... </TreeViewThis 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?

the treeview is not currently supported inside an updatepanel. you will
need a different approach.
