Is there a way to reference the containing tree node of a template generated control on the client side, a radcombobox in this case?  Without using the Find methods.

Those depend on knowing a particular value rather than the relationship of the node and control.  I have a client function that is a handler for the radcombobox OnClientSelectedIndexChanged event, but within that I need to also get a reference to the containing tree node.

Hello Marbry,

The TreeView has a function that can get a reference to the node object if you pass in any of the elements inside the node as an argument. In your case, you can use this function in the following way:
function onClientSelectedIndexChanged(sender, args) {
    var comboElement = sender.get_element();
    var tree = $find("RadTreeView1");
    var node = tree._extractNodeFromDomElement(comboElement);
    console.log(node.get_text());
}
