Using the below code, wired to treeview client side node click event, I get the Sys.WebForms.PageRequestManagerServer.ErrorException javascript error.
The alert pops up as expected, but the ajax request fails...
function
ClientNodeClicked(sender, args)
{
alert(
"ClientNodeClicked!");
var ajaxManager = $find("<%= RadAjaxManager1.ClientID %>");
ajaxManager.ajaxRequestWithTarget(
"<%= RadTreeView1.UniqueID %>","");
}
