Row separator color in datagridview
2 answers
On the MSDN page for DataGridView.DividerHeight
This property is useful for the visual border between frozen and scrollable lines. The extra edge is part of the current row, although it will take on the foreground color of the corresponding DataGridView.
So it looks like you cannot set the color directly, but setting the foreground color of the DataGridView will change it.
