Thanks. I'll try it to see how it works.

You shouldn't ever be able to tell, as they hsould not be public.  But, if they are, then it's easy to find out.  Just grab the Parent property, and cast it to the specific type of the form class.

I understand you would like to have TextBox.Enabled=true but if you are trying to control the user's actions, you need to make it very clear to them what is expected. Upon loading or clearing the form, set the data entry controls read-only. Then upon clicking the [Add], [Edit] or whatever the button is called, the first thing you do is enable your text boxes, radiobuttons and any other controls the user is to access for data entry. If you just hide the cursor, the user clicks on the TextBox and says "What's wrong? The cursor disappeared!" If it is disabled, it is pretty clear the only option they have is to tell the program what they want to do such as [Add], [Edit], etc. I usually have two core methods in most of my forms: Clear() and SetReadOnly(bool value). Upon loading the form or saving a record Clear() is called which sets all the default values for the fields. One of the last lines in Clear() is the call SetReadOnly(true); to disable all the controls. The only option the user has at this point is to click [New] or [Cancel]. If they click [New], I call SetReadOnly(false); and set the focus on the first field I want them to fill in (i.e. TextBox.SetFocus();). Just a suggestion.
