ISMAILRAJPUT,
That's what I was hoping for, but no click events appear in the list of
events in VS designer to implement. A few others do appear, but nothing
apparently useful. How can I get at the OnClick event when it's not there?

Right click event will occure but i think what you need is "Do not Handle
the Event" or if there is a contextmenu attached, remove it.

How can I disable the right click capability of the Web Browser control
that's on a form? I only want it to display the HTML, w/ no popup menu.
TIA,
