I'm setting the grid's datacontext to a dataset with just 100 rows (and 67 columns).

Quite frankly, the gridview's *vertical* scrolling performance sucks - big time. It seems the more columns we have, the worse it gets.  "Deferred" scrolling is not an option (it lags too, BTW).  We need the grid to scroll smoothly as the scroller is dragging down the scrollbar. 

Curiously, horizontal scrolling seems to work just fine, regardless of the number of columns we have in the dataset.

What can we/you do to improve this?

Hi John,

Currently the grid does not support horizontal virtualization - will create cells for all columns no matter if the column is in view-port or not. For Q3 (late October) we will provide this - early beta is expected in September.
