ASP.NET Ria Esssential Pack - Version 1.11 ASP.NET Ria Essential Pack is a library that includes the Silverlight-based versions of ASP.NET GridView and ASP.NET Chart. These controls are based on the RIA principle: they are usual ASP.NET controls with properties similar to GridView and Chart, but they use the in-built Silverlight application for visualizing data in a user's browser.In comparison to their standard analogues, Ria controls have several advantages:1. Rich UI. Because the user interaction is subject of the client side, the application functionality may include anything that could be implemented in a desktop application, including drag and drop, using a slider to change data, smoothing, transparency and so on.2. Short response time. Because the browser doesn't need to interact with the server on every operation, the RIA is usually much more responsive than standard
