Pete,

Doesn't make sense to do this at design time if you use a proportional font (like most of them are).

If you use a fixed font (eg Courier New) then I guess it is just the char width * #chars + space for the margin + something else

You can use a builder, your calculator or - recommended - a few statements in the init() of the textbox, which adjust the width of the textbox once

Also possible is the code I provided in the InteractiveChange ( on this.Value and not on rtrim(this.Value))

In short, you can only set the width for a 35 char field if, and only if, you use a non-proportional font.

But then, is it worth all the trouble. If people complain, explain that you use a proportional font which looks nicer. They'll understand.
