I'm writing a user control that does some filtering on a DataGridView and I need to keep track of the number of visible columns. The DataGridView.DisplayedColumnCount() method is what I believe I want to use, but it has a boolean arg named includePartialColumns that is described in IntelliSense as "true to include partial columns in the displayed column count; otherwise, false." I have checked every reference I can think of including SO and msdn, but I caot find a definition for a partial column. Does anyone have any insight into this?
