I've found that the DesignMode property is set to true when I debug a
component by setting the component project as start-up project. I suppose
that this property is set to true because, in fact, the devenv program is
running, so the actual state is run-time.

This is what I want to do and I am struggling with it:
I have a property which gets displayed in the property grid and when
the user clicks on it, a form shows up which allows the user to select
multiple email id's and when he clicks OK, the list should be displayed

In my web application,in one of the page
where I need to disable the back button of the toolbar.
Suggestions on this are welcome.
Thanks,
