In this article, I will explain how you can display a confirmation dialog from server side in ASP.NET. Suppose you are performing an operation and wish to present the user with a confirmation dialog. Using this code, the user will be shown a confirmation dialog box with "Yes" and "No" buttons. Then on the server side, you can test which button was clicked and take action accordingly.
This code is fully tested. If you still face any trouble using this code, feel free to get in touch with me through the comments section below or the contact page.
