DataGridView WordWrap

To get cell text to word wrap is easy once you know the combination of properties to set:

DataGridView > AutoSizeRowsMode = AllCells
DataGridView > Columns > *Your Column* > Default Cell Style > Wrap Mode = True
DataGridView > Columns > *Your Column* > AutoSizeMode = DisplayedCells

DataGridView Adds Extra Columns

The AutoGenerateColumns property is not available on the design surface of VS, only in code. What a pain. So, to prevent columns from displaying:

Public Sub New() '// or whatever
my_data_grid_view.AutogenerateColumns = False

End Sub
