DoubleClick on Row Header

To handle a double click on row header, handle RowHeaderMouseDoubleClick event of DataGridView:

private void dataGridView1_RowHeaderMouseDoubleClick(object sender, 
    DataGridViewCellMouseEventArgs e)
{
    var rowIndex = e.RowIndex;
    //You handled a double click on row header
    //Do what you need
}

DoubleClick on Column Header

To handle a double click on column header handle ColumnHeaderMouseDoubleClick event of DataGridView:

private void dataGridView1_ColumnHeaderMouseDoubleClick(object sender, 
    DataGridViewCellMouseEventArgs e)
{
    var columnIndex = e.ColumnIndex;
    //You handled a double click on column header
    //Do what you need
}

Using DoubleClick

Also if for any reason you want to use DoubleClick event, here is what you should write:

private void dataGridView1_DoubleClick(object sender, EventArgs e)
{
    var g = sender as DataGridView;
    if (g != null)
    {
        var p = g.PointToClient(MousePosition);
        var hti = g.HitTest(p.X, p.Y);
        if (hti.Type == DataGridViewHitTestType.ColumnHeader)
        {
            var columnIndex = hti.ColumnIndex;
            //You handled a double click on column header
            //Do what you need
        }
        else if (hti.Type == DataGridViewHitTestType.RowHeader)
        {
            var rowIndex = hti.RowIndex;
            //You handled a double click on row header
            //Do what you need
        }
    }
}
