After I set the ShowMessagebox to true and the Show Summary to false the the message box does not display when there are errors on the page. I have included the code for the control and the page. Thank you for your assistance.
C# code from the Control
protected void CustomValidator1_ServerValidate(object source, ServerValidateEventArgs args)
{
if (txtPhoneHome.Text != string.Empty || txtPhoneBusiness.Text != string.Empty)
{
args.IsValid = true;
}
else
{
args.IsValid = false;
}
}
Control Code Source
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="ContactForm.ascx.cs" Inherits="Controls_ContactForm" %>
<style type="text/css">

}
.style2

<script type="text/javascript">
