I have a databound dataGridView. When I click on the new row the DefaultValuesNeeded event is fired and the row is populated with my default values. If I then hit escape, the new row will be deleted.

I have a WinForm app with multiple DataGridViews bound to SortableBindingLists. Under some circumstances, I need to programmatically delete an item from the list that grid is bound to. I can't seem to get the DGV to recognize that it's data has changed, or, specifically, that it has fewer rows. I'm calling dataGridView1.Invalidate(), a...
