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:

<asp:customvalidator id="CustomValidator1" runat="server" ErrorMessage="Sie msen min. 1 Telefonnummer angeben"
		Display="Static" OnServerValidate="ValidateExistanceOfPhones"></asp:customvalidator></P>
<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">

<!--

function validate_form ( )
{
    valid = true;

    if ( document.contact_form.contact_name.value == "" )
    {
        alert ( "Please fill in the 'Your Name' box." );
        valid = false;
    }

    return valid;
}

//-->

</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;

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++.

Greetings!

function validate()
{
  var yrs_check = /[1-2][0-9]{3}$/;
	
  if(yyyy1.value=="" || yyyy2.value=="" || mthOfWage.value=="")
  {
    alert("Please fill in all the required information!");
    return false;
  }
  else
  {
    if( !yyyy1.match(yrs_check) )
    {
      alert("Please enter a the correct year format! [yyyy]");
      return false;
    }
    else if( !yyyy2.match(yrs_check) )
    {
      alert("Please enter a the correct year format! [yyyy]");
      return false;
    }
		
    return true;
}
:
:
:
:
<form method="post" action="process.asp"  onSubmit="return validate()" >

The codes are alright, I guess?
However, when I entered a wrong data format, the file "process.asp" is still loaded.
Please advice.
