It is very tricky to build the necessary javascript that maintains fixed
text (the dashes) within a textbox and moves the insertion point along.
Simply put, HTML wasn't designed to do that. To my knowledge, IE's DHTML
library comes closest to giving you the tools that allow modifing the
inserting point and replacing characters in text.

I recommend letting users enter text in your format and reformatting as they
exit the field. That's what I did in my commercial DateTextBox property,
"Peter's Date Package" (http://www.peterblum.com/datecontrols/home.aspx). In
my case, I developed the ability for the user to omit separators and have
the code re-insert them during reformat. For example, if they type "0312",
the software reformats to 03-12-2004 (determining the year from other
rules.) Peter's Date Package fully supports localization of date formats.
You specify your desired ShortDatePattern and DateSeparator.
