Set the charactercasing property to upper and set the maxlength property to the number of characters you want to stop them at.


>> just realized (ran into it) that a regular win forms textbox does not have a Mask property. So I found out that there is a Masked Textbox in VS 2005. But then I read here in some of the old messages that Masked Textbox is not a good idea. I need to have some text boxes to have a Format (!) - automatic upper case and limit a number of characters to, say, 10 or 15. Will Masked Textbox work in this case or should I seek a 3P products?
