I am creating an orgchart. Data was loaded properly. What I would like to do is selecting a node then export data of the node into an excel. I tried to find a handler that helps me to identify the node where the mouse click is. I tried to implement the handlers provided in the Xamorgchart such as OnMouseLeftButton down, but it never be invoked. It could be that I implemented in a wrong way, I need some advise on this.

Thanks
