Hi, Enrico -

The quick answer to your question is: No, I do not believe there is a simple, easy way to accomplish this.

I think that in order to accomplish what you have described, each of the "clickable" DragObjects would have to have code in their respective Clicked event scripts to first obtain a reference to the parent window (tab control and custom visual user objects will introduce additional levels of parent objects), then trigger an event in that window. I would be hesitant to place the code you have described in the window's Clicked event because it might interfere with any existing or future event processing... I would instead create and use a custom user event.

Best regards, John
