我認爲這幫助ü。

 Point[] oldSelectedCells = new Point[dataGridView1.SelectedCells.Count]; 
     for (int i = 0; i < dataGridView1.SelectedCells.Count; i++) 
     { 
      oldSelectedCells[i].X = dataGridView1.SelectedCells[i].ColumnIndex; 
      oldSelectedCells[i].Y = dataGridView1.SelectedCells[i].RowIndex; 
     } 

     // refresh datagridview 

     dataGridView1.CurrentCell = null; 
     foreach (Point p in oldSelectedCells) 
      dataGridView1[p.X, p.Y].Selected = true;
