Answer 1

You should be able to just add/remove the column from the DataGridView.Columns collection depending on which data source you are bound to. When you bind to the source that needs the column, add it to the collection. When you bind to the other source, before binding, remove the column from the collection.

Here is a link about the Columns collection http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.columns.aspx. Note the mention on the page that you can add/remove and obtain a count of columns by using the collection returned from the Columns property.
