Masked Textbox is an easy to use control that allows a developer to integrate
a textbox that supports a developer defined mask. By further supplying a
Validation expression, you reap the full benefits of this control by only
allowing valid data to be entered when pasting.
By default, this control acts as a normal textbox, but by using the
validation characters, you can specify the mask you wish the user to abide by.
These characters include the letter C for character representation, and the
number 9 for numerical representation. Other special characters are supported
that will only allow that character to be entered. See documentation for a full
list of special characters.
This control was built with IE 5+ and Netscape 6+ in mind, and currently has
no support for Netscape 4.
