Hello:

I am trying to validate a textbox by making the backcolor red when the textbox is null. The required field validator works fine.

<asp:TextBox ID="CityText" Width="200px" runat="server" />

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" Display="Dynamic" ErrorMessage="Required" ControlToValidate="CityText"></asp:RequiredFieldValidator>

<asp:CustomValidator ID="CustomValidator1" runat="server" OnServerValidate="CityText_ServerValidate" ControlToValidate="CityText" ValidateEmptyText="true" Display="Dynamic"></asp:CustomValidator>

        protected void CityText_ServerValidate(object source, ServerValidateEventArgs args)
        {

            if ((CityText.Text == null))
            {
                CityText.BackColor = System.Drawing.Color.Red;
            }

        }
