Can a grid column bound to a DateTime be null?

[Thirsty Traveler]

I have a DataTable with a DateTime column that is bound to a DataGrid. The
grid is configured to display/page a maximum of 10 rows. For visual effect,
I would like to display the grid with a all rows populated to null rather
than have it appear only after the dataset is retrieved and bound to the
table. I can populate 10 rows in the dataset with "" for string columns on
page load, but the data column requires a valid date, which is ugly on the
"blank" grid.

Is there some way to do this?

Actually, it is bound to a GridView control.
