Tim:

Thanks for the help...i got it. I actually was reseting the form on click of a cancel button which also changed the view state. Thefore, the radiobuttons were going away. When the selected setting is called, it seems to call the invalidator, which I believe waits one frame to process...hence the Radiobutton was gone and the error thrown. Instead, i'm calling the reset function on display of the form rather than when its cancelled....

Thanks!

Sam

Sam,

It's hard to tell without seeing your code. I tested the function before posting, so I know it works with my programs. If you can, post your code and we'll get you going.
