<asp:RegularExpressionValidator and RegexOptions.IgnorePatternWhitespace

Question

Is there an easy way of using the RegularExpressionValidator control while ignoring white space?

I can use a custom validator control with Regex and IgnorePatternWhitespace, but it would be good to just have an option in the RegularExpressionValidator control.

Answer 1

Surround your regex with

(?x: )

so "a b c" becomes "(?x:a b c)
