Telerik RadGrid introduces a comprehensive client-side API, which enables you to resize,
move, reorder, select and much more. The control exposes a rich client object model with
various client events which can be wired to execute custom client code and change the data
presentation.
More about the client side API of the control you can learn from the
Client-side API
reference section in the grid documentation:
