New Control - RadVirtualGrid

NEW RadVirtualGrid aims to handle scenarios which require working with large amount of data. This is achieved by triggering an event every time a cell needs a value, the user pushes value, or some data operation occurs and allows the developer to perform the needed action.Since the control does not save any data but the visible cells, the memory footprint is low.

RadGridView

NEW
  • Load-On-Demand - full lazy mode support. Please refer to RadVirtualGrid for such functionality.
FIXED
  • The control cannot be bound to array of objects (object[]).
  • RadGridView does not scroll correctly when AutoSizeRows and EnableFastScrolling are set to true.
