Drop Expand/Collapse Image From Root Node

[Andrew]

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?
