Remarks

This feature executes Ajax requests to load and refresh data a few rows or columns ahead of the user's scrolling to provide a smooth scrolling experience when you display large amouns of data without paging. It is demonstrated in the Virtual Scrolling sample.

This option is ignored if the grid uses paging, columns merging or fixed rows. This option cannot be enabled when using dynamic wijdatasource.
