txtbox validation

I have a txtbox on my web form. I need to check if the second character is a "C" and the next three characters are numeric. Is there a way I can do this with the RegularExpressionValidator?

thanks,
eye

hmm...I THINK

[C]\d\d\d

might be the reg expression.. at least that is the best I can figure out from my book which only has very little info on it

the [C] mean the letter c and \d mean any digit from 0-9

oops..second character

[a-z][c]\d\d\d

shorter version

[a-z][c]\d{3}

error message is still popping up. I'm using "[a-z][c]/d{3}" and placing this value in my textbox "1c234"

I'll keep ya posted...

try this one
[a-zA-Z0-9][cC]\d{3}

that will let any letter or number(upper or lower case) for first
c(upper or lower case) for second, then 3 digits.

it's working....I was placing a digit in the first value...d'uh!


thanks
