Optimizing the RadGrid performance.
Please review the following links on how to optimize the performance of RadGrid:
In the worst case when a grid is bound to huge data in the web server the RadGrid gives great performance. Working with web services and JSON increase the performance:
ViewState size: Some of the grid operations can work with completely turned off ViewState.
In client-side data-binding scenarios you do not need the ViewState also:
Number of requests: Most of the grid images come from the grid CSS sprite which minimizes number of requests to the server for resources. Can be minimized with RadScriptManager and RadStyleSheetManager.
