How can I implement form validation in ASP.NET using UI components?

You can use the built-in validation controls in ASP.NET, such as RequiredFieldValidator, RegularExpressionValidator, and CustomValidator. These controls can be added to your form to ensure that user input meets specific criteria.

Can you give me an example of how to use the RequiredFieldValidator?

Sure! You can add a RequiredFieldValidator like this: <asp:TextBox ID='txtName' runat='server' /> <asp:RequiredFieldValidator ID='rfvName' runat='server' ControlToValidate='txtName' ErrorMessage='Name is required!' ForeColor='Red' />.

What about client-side validation? Is it possible?

Yes, ASP.NET supports client-side validation. You can enable it by setting the 'EnableClientScript' property to true on your validation controls. This allows validation to occur in the browser before the form is submitted.

Are there any UI frameworks that work well with ASP.NET for validation?

Yes, frameworks like Bootstrap and Materialize CSS can be integrated with ASP.NET to enhance the UI and provide better validation feedback.
