Regex works in aspx but not .cs

MargeS · 2012-05-24 10:57:34

I have a RegularExpressionValidator in a .aspx page that validates a string in a textbox. It works perfectly. I have the same Regex in a compiled application and it doesn't work exactly like the aspx version. What could cause the difference in the way the regex works?

MS Doc on the RegularExpressionValidator mentions validation could be different between the client and server.

"On the client, JScript regular expression syntax is used. On the server, Regex syntax is used. Because JScript regular expression syntax is a subset of Regex syntax, it is recommended that you use JScript regular expression syntax in order to yield the same results on both the client and the server."
