So I need to make regex validation case insensitive. I know in the Javascript regex engine you can pass in something like this /regex/i to the constructor of RegExp.
The problem is that with ASP RegularExpressionValidator there is nothing to tell it that the regex is case insensitive and the javascript that does the work on the client side does not give any options to pass this flag.
How have you guys gotten around this issue short of creating a regex like [A-Za-z]. As you can imagine this gets very complex and ugly when the regex is complex.
