Hi,
I have the below requirement.
Do not allow I or O in a particular text box.

I thought of having the client side validation with the regular expression pattern.
But i am not able to figure out an expression for this.

Any help would be appreciated.

Thanks

I'm no expert, but I would probably use something like:

[A-HJ-Z] <-- EDIT: ignore this, it's stupid, sorry. See my next post...

Or is that overly simple?

Two resources that I always find very useful:
Regular Expressions Cheat Sheet
Just has some handy reminders about syntax for regular expressions.

Online RegEx Tester
Tests your regular expressions, to allow you to iteratively improve them.

Dave.

Sorry - that was a stupid answer, and I regret it...

What about just:

[IO]

This will tell you whether either I or O appears in the text box.
