I find myself reusing similar/identical code in order to implement filtering, sorting and virtual paging. In almost all cases, I am simply applying the filters, sort and determining the records to select based on the page as shown in the API.

This code should be inbuilt into the kendo grid. If filterable is true, kendo should implement the filter change event and apply filters automatically; the users should not be forced to define what happens on filter change for every grid instance. Similarly, if sortable is true, the kendo grid should automatically implement default sort functionality.

The same would also be useful for virutal scrolling. If scrollable is set to 'virtual', then the view to be shown in the grid should be automatically calculated on page change.
