How To Limit Input Characters in a TextBox?

Right now the only way is to use the new ForceCase property, which can be one of:

- "upper", "u" - all alpha characters forced to UPPER CASE
- "lower", "l" - all alpha characters forced to lower case.
- "title", "t" - all alpha characters forced to Title Case
- None, "" (default) - no change made to characters

We are looking into adding more such features, such as an InputMask property that will allow input of formatted text, such as telephone numbers, !SSNs, and the like, as well as character filter expressions to limit the characters that can be entered. Nothing definite yet; stay tuned!
