Questions about Row and Column Headers of dataGridView

About Row Headers:

1) Can I write text on them?

2) Can I change their colour, so that they have different colour from all other cells?

3) Can I make this arrow that appears when I click on th开发者_JAVA技巧em to go away?

About Column Headers:

4) Can I change their colour?

Thanks in advance.

Answer to 3)

Handle the CellPainting event:

dataGridView.CellPainting += 
     new DataGridViewCellPaintingEventHandler (dataGridView_CellPainting);

Then for the handler, only respond to a ColumnIndex of "-1" (which indicates the row header):

void dataGridView_CellPainting (object sender, DataGridViewCellPaintingEventArgs e)
{
    if (e.ColumnIndex == -1)
    {
        e.PaintBackground (e.CellBounds, true);
        e.Handled = true;
    }
}
