    Hi Isabelle,

    You can easily check for a given condition about a RadTreeView node by using the OnClientNodeClicked client event. Possible implementation of the event handler for your scenario could be:
    function displayClickedDodeIfEndNode(sender, eventArgs) {
        var currtentNode = eventArgs.get_node();
        var currentNodeCildrenNumber = currtentNode.get_nodes().get_count();
        if (currentNodeCildrenNumber == 0) {

    You can learn more about the client side events of the RadTreeView from our Documentation.
