Context Menus with the TreeView webcontrol

[Guest]

Is it possible to have different contect menus for each node in a TreeView
control.

I see lots of examples on how to do this using Windows Forms, but the the
webcontrol does not seem to support the mouse_up and mouse_down events.

I can set a context menu for the entire Tree no problem, I just define a
value for the "onContextMenu" attribute. but I can't seem to find a way to do
this for each node.

Is this possible?
