ShowMessageBox does not appear

ChuckASP · March 12th, 2010, 11:47 AM

I have perfomed the 'Try it out' up to and including step 7 on page 304 and everything works as it is supposed to. What is odd is that the last 2 steps, 8 and 9 aren't working. The message box does not appear. There are only 3 small change to make. The problem must be someware else. I'f searched the forum and have see where the Java script can cause problems but that looks good to. What else can I check?
Here is the markup for the changes.

Code:

    <td class="style3" colspan="3">
      <asp:ValidationSummary ID="ValidationSummary1" runat="server" 
        HeaderText="Please correct the following errors before you press the Send button" 
        ShowMessageBox="True" ShowSummary="False" />
    </td>

Code:

<script type="text/javascript">
  function ValidatePhoneNumbers(source, args)
  {
    var txtPhoneHome = document.getElementById('<%= txtPhoneHome.ClientID %>');
    var txtPhoneBusiness = document.getElementById('<%= txtPhoneBusiness.ClientID %>');
    if (txtPhoneHome.value != ' ' || txtPhoneBusiness.value != ' ')
    {
      args.IsValid = true;
    }
    else
    {
      args.IsValid = false
    }
  }
    
</script>

Hi Chuck,

Do you see the error message for the custom validator appear in Step 7?

Are you sure the changes were saved correctly and you requested a fresh copy of the page in the browser? Did you try reloading using Ctrl+F%?

If that doesn't help, can you post the full code of the markup and Code Behind?

Cheers,

Imar

Yes, everything displayed correctly in step 7.

I started reading the âHow it worksâ to see if I could find the problem and I saw that I misspelled the âValidatePhoneNumbersâ ClientValidationFuntion. After I corrected that, it worked fine.

Thanks,

Chuck

Code:

    <td>
      <asp:CustomValidator ID="CustomValidator1" runat="server" 
        ClientValidationFunction="VlidatePhoneNumber" Display="Dynamic" 
        ErrorMessage="Please enter your home or business phone">* </asp:CustomValidator>
    </td>

Darn strict JavaScript interpreters.... ;-)

Glad it's working now.
