>-----------------------------------------------------------------------------------------------------------------------------|
Mike, thanks for the reply. I made a couple of attempts at casting to
a button but I must be missing something. Here is a simple example of
what I'm talking about. If any row is selected in dg, then all
buttons except button "A" should be disabled. What do I need to do to
make this happen?
Thanks, Bill...
