CheckChildNodes and LoadOnDemand?

[Doug]

Suppose you have a treeview with CheckBoxes and CheckChildNodes set, and you are using LoadOnDemand.

The user clicks on a checkbox for a parent node whose children have not yet been loaded.

What happens?  Are the child nodes loaded?  If not loaded, is the altered checked state of the child nodes nevertheless transmitted to the server upon postback?

Doug,

I realize your post is 3 years old, but I wanted to provide an answer in the hopes that it helps someone else.

By default, it would not expand them.  However, that behavior is easily accomplished:

function clientNodeChecked(sender, eventArgs)
        {
            var node = eventArgs.get_node();

            if (node.get_checked())
            {
                node.expand();
            }
        }
