Edit: I made the same mistake as Cody in the comments, so I corrected my answer.
It depends on what kind of control he has.
For example, if it is a TextBox , perhaps you can make it ReadOnly instead of disabled. And for some other controls, you could do things like this to make them seem to be disabled without actually disconnecting.
However, if you want to do this correctly, you need to make them the owner or override the OnPaint event and draw the text yourself.
