How Do I: Use the ASP.NET AJAX ValidatorCallout Extender?

The standard ASP.NET validation controls work on both the server and the client. Server-side validation adds to the security of your Web application, while client-side validation adds to the user friendliness of your Web application. This video demonstrates how the ValidatorCallout control from the ASP.NET AJAX Control Toolkit extends the standard validation controls to enhance the user experience by neatly positioning validation messages in callout boxes.

If these only deal with client-side code, should we be setting EnableViewState="false" or does it need viewstate to remember which validation control it's wired up to after a postback?

Is there a limitation on the use of this extender with regard to TextBoxes that have TextMode="password"? I can't get this extender to work with a password field.

Hi all,

I have a problem with my ValidatorCalloutExtender.

When it renders on my browser (IE6) it's shadowed by a dropdownlist placed just to the right of it.

How can I solve this problem?

Thanks in advance.

Hi Joe,

Is it possible to set Custom Error message for Validator Callouts,I need to Use Validator Callout in our project, but our client need to have control on Error Messages.

Which might be that Error messages will be in the xml file ,can we set the error message to custom validator at runtime.

Regards,

KCG
