As per the current implementation of the RadGrid control, if we set the CurrentFilterFunction, that will be used for that column and even with no value, the same filter function will be used (specified in the CurrentFilterFunction). This is not user friendly and one should expect that "NoFilter" will be invoked when there is no value. There is no possibility for invoking the "NoFilter" command when the following properties are set: ShowFilterIcon = False and AutoPostBackOnFilter = True please refer the following link for more information: http://www.telerik.com/forums/filter-not-resetting-if-filtervalue-is-empty-in-client-side-filtering

Add support for custom paging in the RadGrid Virtualization functionality. The idea is to enable the retrieval of part of the data from the source of data instead of retrieving all of the data every time. Without this feature the optimization technique is to cache the data source. Example is available at http://www.telerik.com/support/kb/aspnet-ajax/grid/details/virtualization-and-custom-paging
