I have an ASP.NET website with a regular expression validator text box.

I have changed the expression in the regular expression validation property "validator expression" and after compiling (rebuild) and running, the validation CHANGEs are not reflecting.

The previous validation is working fine but the changed validation is not working.

Please help me!

edit:

First code:

([a-zA-Z0-9_-.]+)\@((base.co.uk)|(base.com)|(group.com))

Second code:

@"([a-zA-Z0-9_\-.]+)@((base\.co\.uk)|(base\.com)|(group\.com)|(arg\.co\.uk)|(arggroup\.com))"
