Problems with CustomValidator...

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:

Code:

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

Code:

	<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

Don't you have to call "Validate()"? Maybe you do somewhere else in your code...?

This is an excerpt from a posting on Google Groups that might help you with the client-side function...

Quote:

Ok, you can do this using a CustomValidator.
1. Add a custom validator to you form.
2. Set the control to be validated.
3. In the ClientValidationFunction field enter the function name you want called
4.The function name will need to accept 2 parameters (source, arguments)
5. Within the function you can do anything you need to. To cancel the post "arguments.IsValid = false"

Example
<script language="javascript">
function MyScript(source, arguments){
//You can do anything you want in here.
//Using the window.event.srcElement.name you can determine what button or event caused you method to be called
arguments.IsValid = confirm("Event type = " + window.event.type + "\nEvent Source = " + window.event.srcElement.name);

//arguments.IsValid = false; Cancels the Post
//arguments.IsValid = true; Validation passes let form post
}
</script>
