Hi,

What ClientSideMode are you using?

Stoyan

For displaying a context menu, better handle the event on the client side. You could assign the name of some JavaScript function to the NodeClickedScript or LinkClickedScript properties, and the control will invoke them when the user clicks an item.

There is also a ClickedScript that should be called when the user clicks an unoccupied area of the diagram, but at this time it is supported only in JavaApplet mode. You could still detect clicks anywhere on the diagram by attaching a mouseDown handler to the DIV element whose ID equals to DiagramView.ClientID.

I hope that helps,
Stoyan
