Working in IE 8, mostly, but trying to write a portable solution for
modern browsers.
I'm catching the 'Showing' client-side event of the RadContextMenu
and trying to adjust it's coordinates. The clientX, clientY and x,y
members of the DOM event cannot be assigned a new value. Visual Studio
breaks with a "htmlfile: Member not found" error.
My goal is to get a RadContextMenu to show inside a RadEditor when
the user clicks in it (under certain conditions, this is a requirement
from management). So I capture the onclick event for the RadEditor's
content area (radEditor.get_document().body;
). I then call show(evt)
on the context menu, where 'evt' is the event object corresponding to
the click event.
Because the RadEditor's content is in an IFRAME, you have to adjust
the position of the click event before the context menu displays. This
is done in the "Showing" event. However, I cannot assign a value to the
members .clientX and friends. It's as if javascript has temporarily
forgotten about integer + and += operators.
Is it possible that these members have become readonly/const at some
point?
