    Can anyone think of a way to drop the expand/collapse image from the root node of a tree view only so that the root item is sitting by itself without both the option to expand/collapse the tree and without the image which would do so.  I still want the expand/collapse image for all sub sections of the tree just not for when I have a root node which would literaly collapse the entire tree to nothing.

    Any thoughts?

    Hi Andrew Nagel,

    Try adding following javascript side code in client-side pageLoad() function as shown below.

    JavaScript:
     
    <script language="javascript" type="text/javascript"
    function pageLoad() 
        var treeView = $find("<%=RadTreeView1.ClientID%>"); 
        var node = treeView.get_nodes().getNode(0); 
        var toggleElement = node.get_toggleElement(); 
        if (toggleElement) 
        toggleElement.style.display = "none";  
    </script>

    Hi Krishna,

    What if you replace <%=RadTreeView1.ClientID%> with <%# RadTreeView1.ClientID%>

    Do you get the same error?
