This demo illustrates the optimized performance techniques incorporated in the ASP.NET 3.5 build of RadGrid. The control takes advantage of the Entity Framework and performs sorting/filtering/paging operations on a database server. This technique significantly reduces the time necessary to process these actions "behind the scenes" and allows you to handle millions of records within a few milliseconds.
For better visual indication we output the period of time between the Init and Render stages of the control lifecycle just below the grid table.
You may also see how to utilize OpenAccess ORM, Telerik's free enterprise-grade ORM, to generate the data access layer for your app in just a few mouse clicks. You can download the Software Development Kit (SDK) for OpenAccess here. By doing the heavy lifting, OpenAccess can save you between 20% and 85% of development and testing time.
