Exception Problem

Hi
I tried to use with "PropertyGrid" control and I got the following
message: "An unhandled exception of type 'System.Security.SecurityException' occurred in WindowsApplication8.exe Additional information: Request failed."
What does it means?
Thank you

You should handle the exception in a try...catch block and then print out the exception message details. This will give you more information.

when does the exception occur, in the form designer when you drop it on, or at run time?
