Description

I was looking for a good way to exclude a DataColumn when the DataGridView is autogenerating its DataGridViewColumns. I somehow stumbled upon a way to do it: just setting the DataColumn.ColumnMapping = MappingType.Hidden does exactly what I wanted.

I think this should be mentioned at least on the How to: Remove Autogenerated Columns from a Windows Forms DataGridView Control, better yet also in the How to: Autogenerate Columns in a Data-Bound Windows Forms DataGridView Control, and even better throughout the DataGridView docs.
