Regular Expressions

I never really got the hang of regular expressions, but I can do some very simple things. Now if your putting all of my code into a file to test it, just add this one below the last. Remember that you aren't limited to one validator per control, you can have as many as you like!

<asp:RegularExpressionValidator runat="Server" ControltoValidate="FName" ErrorMessage="Your name isn't in the correct format!" ValidationExpression="\S+\s\S+" />

Now this checks to see weather the field matches the pattern in the ValidationExpression property, in this case the pattern in - "Any number of non-space characters, followed by one space, followed by any number of non-space characters", this is the normal format for a name.
