[Solved] trackChanges() not working for unchecked nodes?

[Chris Sears]

I'm trying to implement a "check all children" scenario in RadTreeView. Basically, when a user checks a parent node, all child nodes should be checked and disabled. When a parent node is unchecked, all child nodes should be unchecked and enabled.

When nodes are checked using client side code, everything seems to work fine. However, if a child node was checked when the page was loaded and only client-side code is used to uncheck it, the node is reported back to the server as being checked.

Is it possible that unchecking a node isn't successfully tracked by trackChanges() and commitChanges()?

Here's the client-side code I'm using:

function onUnitNodeChecked(sender, eventArgs){
    var node = eventArgs.get_node();
    var childNodes = node.get_nodes();
    if (childNodes.get_count() == 0) {return;}
    var tree= $find("<%= tvUnits.ClientID %>");
    tree.trackChanges();
    if (node.get_checked()){
        checkAllNodes(childNodes, true);
    } else {
        checkAllNodes(childNodes, false);
    }
    tree.commitChanges();
}

function checkAllNodes(nodes, check){
    for (var i=0; i<nodes.get_count(); i++){
        var node = nodes.getNode(i);
        if (check){
            node.set_checked(true);
            node.set_enabled(false);
        } else {
            node.set_enabled(true);
            node.set_checked(false);
        }
        checkAllNodes(node.get_nodes(), check);
    }
}

I have almost same issue. I was using the same JS code as the client side checkbox demo. Even adding the trackChanges() & commitChanges() methods doesn't help. What happens is when I postback it just sends what I used to have selected BEFORE I use the parent node to deselect/select the nodes.

I have another issue involving the client side select method as well but I will start new thread.

Hi Chris,

This turns out to be a bug with the RadTreeView control and it is being tracked for fixing. Thank you for reporting it.
