show content

Hi,

How can i display content only on selected ending item(when item has no other sub items) and how can i check this WITHOUT postback at each selected node? Thanks!

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) {
        alert(currtentNode.get_text());
    }
};

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