Validation Controls

Question

Hi friends... i have a question about validation controls that whenever we using any validation controls in our web application an error comes 'UnobtrusiveValidationMode'. Why this error comes ?

Ramesh Maruthi · Answer

Reason: Specifies how ASP.NET globally enables the built-in validator controls to use unobtrusive JavaScript for client-side validation logic. If this key value is set to "None" [default], the ASP.NET application will use the pre-4.5 behavior (JavaScript inline in the pages) for client-side validation logic. If this key value is set to "WebForms", ASP.NET uses HTML5 data-attributes and late bound JavaScript from an added script reference for client-side validation logic. Example:
