InputMask  Review

The Input Mask server control is an input control that lets the user enter text inside a preset mask. The preset masks are completely customizable to any set of alpha-numeric characters and can limit any spot within the mask by alphabetic, numeric, or alphanumeric placeholders. The text displayed in the Input Mask control is specified or determined by using the Text property and the inputted, or un-masked, text is determined by using the TextUnMasked property which is read-only.
