Are OnNodeClicked and NodeClickedScript mutually exclusive?

Hi,

For the most part, I want to handle the nodeClicked event in Javascript, but on occasion I need to deal with it in code behind.
I can cause a postback using some other techniques, but I just wanted to clarify that the server side event will not fire, if I have NodeClickedScript specified.

Here's what I was hoping would work:

Code (Javascript)
Select All
function onClientNodeClicked(sender, args)
            {
                var tag = args.getNode().getTag();

                switch (tag)
                {
                    case "client":
                        // handle this right here
                        args.set_cancel(true);
                        break;
		    case "server"
			// Don't cancel this request - allow code behind to handle
			args.set_cancel(false);
			break;
		}
}


Thanks in advance.
Jim

Hi,

Yes, they are mutually exclusive, there's no post-back script generated for nodes if either NodeClickedScript or NodeDoubleClickedScript is set.

You should be able to implement that easily by leaving NodeClickedScript unset, and instead handling the CreatingAreaElement event. You can add an onclick attribute from the CreatingArea event handler only for some nodes, and the control will not generate post-back click handlers for them. The remaining nodes will post back automatically and raise the server side click event.

I hope that helps,
Stoyan
