Maintain selections while scrolling virtual

Hi

I am trying to preserve the selected rows of a grid while virtual scrolling. I can see that sometimes the selection is maintained after the first time a virtual scroll is performed but after that it is not.

I have tried hooking into the virtual scroll requesttype but can't seem to get this to work properly.

Any advice?

Regards Mike
