     Hey tianshuo,

    You can mess around with the following code snippets to come up with a solution for your request.
    If none of these help, please post your code and I will gladly help you as best I can.

    to get an instance of the Tree you can do this in BLOCKED SCRIPT

    var tree = igtree_getTreeById("TREENAME");

    just replace "TREENAME" with the actual ID of your UltraWebTree.

    you'll also need the node that is selected.

    var node = tree.getSelectedNode();

    you'll want to check to see if this parent node has any child nodes...

    var childNodes = node.getChildNodes();

    if (node == null || childNodes .length == 0) {
            return;
    }

    if it does have child nodes then you'll want to loop through the child nodes and
    check the checkboxes.

    for (i = 0; i < childNodes.length; i++) {
         // Place checkbox code in here //
    }

     
    I hope this helps!
