Regex in asp.net for allowing only characters with single space?

RachitSharma

I want to allow a user to enter only characters and with single space in a textbox. What i have tried is :

^[\w\.:\(\)\[\]{}\-_](?: ?[\w\.:\(\)\[\]{}\-_])*$

it is blocking all but allowing digits also . How to make it correct such that it only allow characters and no digits but a single space between words? Thank you.

I'd use:

^[\p{L}.:()[\]{}_-]+(?: [\p{L}.:()[\]{}_-]+)*$

Where \p{L} stands for any letter.

Edit:
I've changed \pL to \p{L} because it's not supported by .NET.
Thanks to Alan Moore.
