I want validation expression for required field validator and the numeric validator together for phone number

  <asp:TextBox ID="txtPhonenumber" runat="server" MaxLength="11" TabIndex="11" onKeyPress="return validateNumbersOnly();" ></asp:TextBox>

            <asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ErrorMessage="Enter Phone Number" ControlToValidate="txtPhonenumber" ></asp:RequiredFieldValidator>

this code works only if field is empty

<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ControlToValidate="txtPhonenumber" ErrorMessage="Only Numbers" Display="None" ValidationExpression="^\d+$" ></asp:RegularExpressionValidator>

ValidationExpression="^\d+$" use this for numeric format validation
