I want selection on the client to cascade down, preferably while allowing ctrl-clicks

[C]

In my tree, the leaves are the data carriers, but I want a click on a particular node to (visually) select itself and all its descending nodes. I am then using the list of selected nodes in an Ajax request.

But I haven't been able to figure out how to accomplish this.

I started out by selecting all the node's children:

var toSelect = !node.get_selected();

if (toSelect)
                node.select();
            else
                node.unselect();

 children.forEach(function(child) {
                if (toSelect )
                    child.select();                    
                else
                    child.unselect();
            });

This does indeed select all the nodes. The problem though, is that it does not show (they don't turn blue). So I was looking for a way to do this through the Telerik client side API, but failed. So I turned to Jquery:

var tree = $find("rtCustomerGroups");
var nodes = tree.get_nodes();

nodes.forEach(function(node) {
if (node.get_selected())
node.addClass("rtSelected");
else
node.removeClass("rtSelected");

The problem with this approach is that, while it works visually, the browser does not seem to like it - as it's complaining (sometimes) with a typeError saying addClass/removeClass aren't functions.

This also breaks the javascript as the next line, calling the Ajax function, never gets run.

This really bugs me, as the selection really works the way I want, including multi selection with ctrl click.
