>There is a "Columns" collection on the DataGridView where you can define column header names, what they are bound to, etc.

I see the column collection, but it is not aware of the Business Object that I have set in the BindingSource property of the grid. In other words, I would expect it to show me all the columns in the BO, so I can choose which ones to show.

Even so, if I manually add a column, it ignores it, and just adds all the columns from the BO anyway.

Remeber, I am talking about the mmDataGridView grid object running against a mm Business Object class that is set in the BindingSource property.
