By the way, the equivalent of the iif() from VFP would be like this:
TitleLabel.Visible = TitleCheckBox.Checked ? true : false
? : is a basic operator - a triadic one.

In this particular case, since we already have a value of type bool, the direct assignment (as shown in another reply in this thread) is simpler, of course.

Also, the keyword This is not required in many cases, although it can help with Intellisense.

Doesn't the compiler complain if you use "=" instead of "==" in the if()?
