These operations usually require postbacks to fetch the sorted/filtered data from the server, this is how server-side data bound controls work. With this in mind, I can offer two suggestions:
- use client-side binding: http://demos.telerik.com/aspnet-ajax/grid/examples/data-binding/client-side/client-data-source-binding/defaultcs.aspx
- OR, use AJAX to benefit from partial page rendering. The easiest way to do this is to wrap the RadGrid in a RadAjaxPanel control.
You can find more details on the matter in the support ticket you had opened with the same question and that was answered by my colleague two days ago.
On a side note - I would advise posting in the most relevant forum in order for your question to reach the most relevant audience. In this case you would have needed the RadGrid for ASP.NET AJAX Forum (http://www.telerik.com/forums/aspnet-ajax/grid
) and not the Telerik Platform forum. Another suggestion that can help you get better results is running a search for your question first, because most of the similar getting started questions have already been asked and have answers readily available.
