保持數據網格視圖的光標點特定列始終

Question

我有這樣一個數據網格視圖：

我對窗口工作application..here司機專欄中，我得給司機id..then我點擊進入..那時光標正在移動下一行釋放按鈕.. 我不想移動光標下一行按鈕..在點擊輸入後，我想讓我的光標移動到下一行驅動程序ID列.. 如何我可以設置標籤順序只在特定的列上。

任何幫助是非常可觀..

下面是創建從DataGridView派生的自定義類和設置的ENTER鍵，以便將沿着該行移動行爲的代碼，但跳過最後一列（在OP案例中的按鈕列）

class MyCustomDGV : DataGridView 
{ 
    private int currentCol = 0; 
    private int currentRow = 0; 

    // Store the current cell position. 
    protected override void OnCellEnter(DataGridViewCellEventArgs e) 
    { 
     currentCol = e.ColumnIndex; 
     currentRow = e.RowIndex; 

     base.OnCellEnter(e); 
    } 

    protected override bool ProcessDialogKey(Keys keyData) 
    { 
     // Extract the key code from the key value. 
     Keys key = (keyData & Keys.KeyCode); 

     // Handle the ENTER key as if it were a RIGHT ARROW key. 
     if (key == Keys.Enter) 
     { 
      if (currentCol >= this.ColumnCount - 2) 
      { 
       return this.ProcessEnterKey(keyData); 
      } 
      else 
      { 
       return this.ProcessRightKey(keyData); 
      } 

     } 

     return base.ProcessDialogKey(keyData); 
    } 

    protected override bool ProcessDataGridViewKey(KeyEventArgs e) 
    { 
     // Handle the ENTER key as if it were a RIGHT ARROW key. 
     if (e.KeyCode == Keys.Enter) 
     { 
      if (currentCol >= this.ColumnCount - 2) 
      { 
       return this.ProcessEnterKey(e.KeyData); 
      } 
      else 
      { 
       return this.ProcessRightKey(e.KeyData); 
      } 
     } 
     return base.ProcessDataGridViewKey(e); 
    } 

    protected override void OnKeyDown(KeyEventArgs e) 
    { 
     if (e.KeyCode == Keys.Enter) 
     { 
      if (currentCol >= this.ColumnCount - 2) 
      { 
       e.SuppressKeyPress = true; 
       e.Handled = true; 
       this.ProcessEnterKey(e.KeyData); 
       return; 
      } 
      else 
      { 

      } 
     } 

     base.OnKeyDown(e); 
    } 
}
