Have a RegularExpressionValidator with proper regular expression validating the textbox.

Well still you could use regular expression fro validation. there will not be any control for that but since it is a windows application you should be able to do it.

But if your requirement is to allow only alphabet in the MaskedTextBox then I think you can consider using mask character ? in the Mask property

C#

MaskedTextBox1.Mask = "???????";

The ? charcater allows a
Letter, optional. Restricts input to the ASCII letters a-z and A-Z. This mask element is equivalent to [a-zA-Z]? in regular expressions. as explained here.
Mask elements for Mask property of MaskedTextBox[^]
