RegularExpressionValidator not firing on white-space entry

Question

I want to validate string containing only numbers. Easy validation? I added RegularExpressionValidator, with ValidationExpression=\"/d+\".

Looks okay - but nothing

Answer 1

Your question is a little hard to follow, but if you are asking how to write a regular expresion which only accepts digits I think your mistake is in using forward-slash instead of backslash. Try

"\d+"
