Generating PayPal Encrypted Website Payments button programmatically on the fly had never been easier before. Using this Control/Component, Encrypted Website Payments buttons can be generated on the fly either from design-time GUI or programmatically by providing the Certificate Parameters.
If you do not have PKCS12 and PEM certificates, Guess What!!! The design time GUI will generate those certificates for you. You just need to stick to this control. The following shot shows the usage in Web Form, but our online documentation shows details about using in ASP.NET MVC Framework as well.
For the Web Form context, IPN & PDT are considered as if those are the very control's server-side events. IPN & PDT variables are available as the properties of Event Argument Object. Thus, a developer can design a single page for the complete e-Commerce logic by using a PayPal Button in a web form and attach event handler methods for IPN/PDT events. Although you can use different page dedicated for IPN/PDT; this control comes with dedicated IPN/PDT handlers as well. It is also easy to handle IPN/PDT in the ASP.NET MVC Context. You can simply provide the Controller/Action URL for IPN and PayPal Return properties, and the component will do the rest.
State management is one of the key requirements for any application/website developer, and so ViewState technology was developed for ASP.NET Web Forms. But when you are using PayPal Website Payments Standard, you are forced to let your customer leave your website before going to PayPal website, and after successful or canceled payments, your customers are transferred back to your site from PayPal website. At that point, you have lost your ViewState data. When you are using ASP.NET MVC, you do not even have any ViewState at all. Even though, PayPal offers few pass through variables like ItemNumber, Custom, Invoice, etc, yet, you do not have complete freedom using those pass-through variables as those are meant for special purposes, and the values of these pass-through variables are visible to your customers. Moreover, those pass-through variables are of limited length. To overcome this limitation, we have implemented a special Collection type property named AdditionalDataItems. It is the State Management solution both for ASP.NET Web Form and ASP.NET MVC Context. You can store as many data as you want into AdditionalDataItems property, and you will be able to access this property value in IPN handler or PDT handler. You can also store sensitive data to this property as this property value is stored in a temporary folder in your server and never sent to the client's browser. The following shot demonstrates this feature for Web Form context, but the online documentation explains this features both for Web Form and MVC.
