The standard Kendo Grid can be super simple, but it can get a bit complicated when you’re upgrading older systems. In this case, we have a old ASP.net/WebForms system with VB.Net Code-Behind. At a later date, we’ll be converting it to WebApi, but for now we’ve had to make some updates on an older machine. We decided to use Generic Handlers, since they are extremely flexible and can later be converted fairily easily into C#/WebApi. It took us a while to get them to work. We’ve written up an example we used while playing around locally. It may be helpful to those of you doing supporting clients while conversions are not finished.
