Hello,

To set an alert to a node when it is selected, you can use OnNodeSelect Client-side event like following:

function WebTreeView1_OnNodeSelect(controlId, node)
{
   var WebTreeView1 = ISGetObject(controlId);
   if (node.Text == "Archive Folders")
      alert("This node cannot be selected")
   return true;
}

However, this event can only be applied in a single WebTreeView without integrating it into WebCombo. If you integrate WebTreeView with WebCombo, this event will never be invoked since combo will recognize the TreeView as the data item.

I haven't figured it out on how we can implement this when WebTreeView is integrated with WebCombo. I will try to discuss further with the developer team, whether this scenario is possible or not.

Thank you and have a nice day.

Regards,
