I have a validator like the one below. Right now it's only validating one control, but there are many controls on the page with the same validation criteria. How do I assign it to multiple controls? Do I really need to duplicate the validator?<br />

                <asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" 
                    ErrorMessage="Only alphanumeric  values are allowed for page names." 
                    Display="None" 
                    ControlToValidate="TextBoxCreatePage" 
                    ValidationExpression="^[a-zA-Z][a-zA-Z0-9_]+$" 
                    SetFocusOnError="True" />

How do I validate multiple controls with the same Validator?

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.
