I'm not sure, but I think you are after something like this using the CellFormatting Event:

Private Sub MainGridView_CellFormatting(ByVal sender As Object, ByVal e As _
System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles MainGridView.CellFormatting
With Me.MainGridView.Columns(e.ColumnIndex)
Select Case .Name
Case "Scans"
e.Value = IIf(CType(e.Value, Boolean), "Yes", "No").ToString

Case "Genre"
e.Value = String.Concat(GetGenreName(CType(e.Value, Integer)), ": ", _
Me.MainGrid.Rows(e.RowIndex).Cells("Style").Value)
End Select

End With
End Sub

In the above, in the column named "Scans", the db's Boolean values are displayed as a string value
rather than True or False.

In the column named "Genre", a concacted string is displayed which consists of a string value based
on the db's genre integer value, plus the string value from a hidden column named "Style".


You can also use "e.RowIndex" to target specfic cells.
