Are there any recommendations or special implementations developers have done to use grids in a touchscreen environment?  We have implemented a few things in the past including custom scrollbars and integrated paging methods, but I am curious about other ideas.

Specifically, when looking at an iPhone or similar touch-based device, the ability to touch and drag to scroll a list/grid is a powerful user tool that people obviously love and has significantly increased usability.  Has anyone done this with the Infragistics grid?  If so, how did you do it.  If not, does Infragistics have any recommendations on this?
