I have a DataGridView bound to an ObservableCollection. The Grid initializes
and fills. As soon as I click anywhere in the grid I get this exception. I
think I have had this one before but don't I can't figure out what the
problem is this time.

Index -1 does not have a value.

What happens in the click event for the datagridview?

I did not have one. I added one and it was never executed.

I did get A CurrentCellChanged event twice. The current cell went from 00 to
null.
Then a MouseDown event followed by a RowEnter event.

I never got a Click event.

I was getting something similar, although I wasn't using an
ObservableCollection, but rather a List. I was attempting to rebound the
datasource to refresh the display, and ran in to the same exception (thrown
with an identical callstack).

I got around this by binding my collection to a BindingSource, and then
binging the BindingSource object to the DataGridView. Then, whenever I
needed to refresh the collection, it was a matter of calling ResetBindings on
my BindingSource object.

Hope it helps.
