To unobtrusive validation, we need to include the necessary jQuery . These scripts can be downloaded from the jQuery website or included via a CDN. In this example, we have included the scripts locally in the “Scripts” .

Next, we need to add the `jquery.validate.unobtrusive.min.js` script to enable unobtrusive validation. This script in conjunction with the `jquery.validate.min.js` script to provide validation .

“`csharp



The `RequiredFieldValidator` control is used to validate that the `txtName` textbox is not left empty. The `ErrorMessage` property specifies the message to be displayed if the validation fails.

With the necessary scripts and validators in place, the unobtrusive validation will automatically kick in when the form is submitted. If the name field is left empty, an error message will be displayed next to the textbox.
