This winform app uses datatables in typed datasets bound to data entry controls.

I'm getting weird results with the maxlength property of textboxes.

A maxlength of 2 works exactly as you'd expect. You can enter 2 or fewer characters into the textbox.

With maxlength of 5, however, I can only enter 3 characters. In order to enter 5 I must make the maxlength 8.

Character casing is upper, but I can't find anything about that.

Any ideas?
