How can I integrate validation controls in ASP.NET?

You can integrate validation controls in ASP.NET by using built-in controls like RequiredFieldValidator, RangeValidator, and CustomValidator. These controls help ensure that user input meets specific criteria before processing.

Can you give me an example of using the RequiredFieldValidator?

Sure! You can use the 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?

For client-side validation, you can set the EnableClientScript property of the validators to true. This allows validation to occur in the browser before the form is submitted.

Are there any custom validation options?

Yes, you can create a CustomValidator control where you define your own validation logic in the server-side or client-side code.
