Smart Rendering & Mass Select


I have a Grid control setup with smart rendering with a few hundered items in. I need the end user to be able to select which items they want, which I will then use getSelectedId to pass the ID’s of these rows to the next stage in my application.

If a user selects the top row, then scrolls down to the bottom row, holds the shift key and selects the bottom row. The only rows which get selected are the ones which are loaded (and displayed) at the top and bottom (which amounts to about 30, rather than the 300 which I have). Can you recommend any way in which my desired functionality can be achieved? I need to keep smart rendering as it takes a long time to load.
