Question : Changing a backcolor of a row in datagridview paints the entire grid+vb.net 2005 windows programming

Hi,
This is a very strange thing as soon I change backcolor of a dg row I can see the entire grid being painted this is a serious overhead in performance.Any suggestions I have setting backcolor on cell formatting event

Public Sub SortingDgRowFormatting(ByVal dg As DataGridView)
'This is to retain the formatting of the datagridview after sorting.As sorting of a dagridview column resets the grid
Dim i As Integer

For i = 0 To dg.Rows.Count - 1
If Not IsDBNull(dg.Rows(i).Cells(0).Value) = True Then
If dg.Rows(i).Cells(0).Value = True Then
dg.Rows(i).DefaultCellStyle.BackColor = System.Drawing.SystemColors.InactiveCaptionText
Else
dg.Rows(i).DefaultCellStyle.BackColor = Color.White
End If
End If
Next

Any suggestions?

End Sub
