ASP.NET: Problems with CustomValidator...

Oct 23rd, 2003

Hi!

I have a litte problem with my CustomValidator.

What my CustomValidator should do:
The CustomValidator should check if 2 textboxes are empty..
if yes he should diplay a message.

This is my code:

 Help with Code Tags 
 ASP.NET Syntax (Toggle Plain Text) 
<asp:customvalidator id="CustomValidator1" runat="server" ErrorMessage="Sie m�ssen min. 1 Telefonnummer angeben"
		Display="Static" OnServerValidate="ValidateExistanceOfPhones"></asp:customvalidator></P>
<asp:customvalidator id="CustomValidator1" runat="server" ErrorMessage="Sie m�ssen min. 1 Telefonnummer angeben"
		Display="Static" OnServerValidate="ValidateExistanceOfPhones"></asp:customvalidator></P>

 Help with Code Tags 
 ASP.NET Syntax (Toggle Plain Text) 
	<script runat="server">
		void ValidateExistanceOfPhones(object source, ServerValidateEventArgs args)
		{
			args.IsValid = !((m_txtTelephoneNumber.Text.Length == 0) && (m_txtMobileNumber.Text.Length == 0));
		}
	</script>
	<script runat="server">
		void ValidateExistanceOfPhones(object source, ServerValidateEventArgs args)
		{
			args.IsValid = !((m_txtTelephoneNumber.Text.Length == 0) && (m_txtMobileNumber.Text.Length == 0));
		}
	</script>

the calidator check ValidateExistanceOfPhones. but when args.IsValid = false the message isn't
shown. What is the problem??!
Make I something wrong?

2. quastion: is it possible to check the state of the 2 textboxes on the client side?
when YES how?

best regards,

gicio

I am posting this reply in hopes that someone will be kind enough to return the favor. My question is posted right below yours. Anyway, here's the solution to your problem. You said you would be able to validate via client side, correct? Well, here's a working form with validation (writting in client-side javascript). Enjoy.

--copy below here--
<html>
<head>
<script language="JavaScript">



</script>
<title>Form Validator</title>
</head>

<body>

<form name="contact_form" method="post"
action="test.html"
onSubmit="return validate_form ( );">

<h1>Please Enter Your Name</h1>

<p>Your Name: <input type="text" name="contact_name"></p>
<p><input type="submit" name="send" value="Send Details"></p>

</form>

</body>
</html>

Just thinking it should be

!= as opposed to args.IsValid = !(....blah...blah)

args.IsValid = !((m_txtTelephoneNumber.Text.Length == 0) && (m_txtMobileNumber.Text.Length == 0));

Is not really the way to go. Why are you having a boolean value come from a condition logic statement?

I would do something like this;

 Help with Code Tags 
 ASP.NET Syntax (Toggle Plain Text) 
if m_txtTelephoneNumber.Text.Length ==0 && m_txtMobileNumber.Text.Length == 0 {
   args.IsValid = false;
}
else
{
   args.IsValid = true;
}
if m_txtTelephoneNumber.Text.Length ==0 && m_txtMobileNumber.Text.Length == 0 {
   args.IsValid = false;
}
else
{
   args.IsValid = true;
}

Sorry if my C# is not exactly correct, I am more of a VB guy than C# or C++.
