Hi,
         In the treeview we have nodes that has child elements not visible , For this we add icon using rtPlus and rtMinus class. On the same treeview we have nodes that does not have any child.We need to place an icon . How do i target these nodes in CSS?

Hi thomson,

Please try the following JavaScript to add an icon to the RadTreeNode which doesn't have any child.

JavaScript:

function pageLoad() {
    var tree = $find("<%=RadTreeView1.ClientID %>");
    for (i = 0; i < tree.get_allNodes().length; i++) {
        if (tree.get_allNodes()[i]._hasChildren() == false) {
            tree.get_allNodes()[i].set_imageUrl("delete-icon.png");//set the icon url here
        }
    }
}

Thanks,
Shinu.
