validate email address

How to validate an email address in

To validate an email address in, use the RegularExpressionValidator. In the validate expression property of the RegularExpressionValidator, select internet email address.

This is how the aspx code would look like

        <asp:TextBox ID="txtEmail" runat="server"></asp:TextBox>
        <asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server"
            ErrorMessage="Please enter a valid email address" ControlToValidate="txtEmail"

If you are a beginner, look at the screen shots below
