RadGrid for ASP.NET AJAX

Telerik RadGrid is designed to eliminate the typical tradeoff associated with ASP.NET grid controls - rich functionality at the expense of weight and performance. Thanks to its innovative architecture Telerik RadGrid is extremely fast and generates very little output. Added to this is true cross browser support - Internet Explorer, all Gecko-based browsers, and Opera.

At the same time Telerik RadGrid delivers top-of-the line features:
