This is a result of a request made by John F for dTextBox objects to have the ability to limit the amount of characters that can be entered. I added a TextLength? property that will dynamically adjust the value in a way similar to the ForceCase? Property.

I created a full suite of unit tests for this property. The only thing the UT doesn't do is check for the dynamic updating when a user enters characters in a text box. I checked that by hand and it seems to work. Also, I checked that it was playing well with ForceCase? and everything seemed to be working well. However, I would encourage people to play with this and report any bugs like usual.

This only affects string textboxes. I figured it would be useful so you don't pass a bizobj a 10 char string when the db field is 2 characters long. Let me know what you think.
