How to set the RegularExpression

ad
I want to limit the iput of Textbox:
1.The input character must within '0'-'9' or 'a'-'d', for instance
a091b, d23c, 123, ad.. is ok, but f9a, ddu.. is not ok
2. null value is ok

I set RegularExpressionValidator to a textbox, but how can I set the
RegularExpressionValidator.ValidationExpression?

I think the pattern would be something like this:

^[0-9a-d]*$

I hope this helps.

Hi ad,

I would highly recommend checking out http://RegExLib.com. I like their
"Cheat Sheet".
