PayPal Gateway Integration in ASP.NET

Introduction

If you are developing an ASP.NET web application and you require some payment gateway integration, then here is a simplified option to integrate PayPal with your application.

Description

In this article I will explain thoroughly all the requirements and techniques for integrating PayPal in your web application.

Nowadays PayPal is the most popular payment gateway worldwide because it is totally free to integrate and PayPal does not charge anything for opening an account, you will pay PayPal when you get paid. And the amount is also lower than other payment gateways.

THE DESIGN PAGE :

This is the test page ...you can create as per your requirement.

Here we created four function to add new row...AddNewRow() and set previous data in gridview.
