Below is my design code for required field validator that checks whether user has entered value in 'textbox' if not it should display error message "name required". But my RFV is not prompting the error message on clicking button without entering name.But the star symbol i had assigned is popping up but not the message.
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
ControlToValidate="TextBox1" ErrorMessage="Name Required" Font-Bold="True"
ForeColor="Black">*</asp:RequiredFieldValidator>
