バインドされていないDataGridViewCheckBoxCell設定値

問題があります。私のコードには、DataGridViewとUnBound CheckBoxColumnが含まれています。私のダイアログボックスは、リストから選択した部屋のためのものでなければなりません。 2回目は、初めて何を選択したのかを確認します。バインドされていないDataGridViewCheckBoxCell設定値

私は突き止めることができないということが起こっている奇妙な何か。 //Not working!!行にブレークポイントを設定して、私が投入している5つのうち2つの部屋の人為的なリストを渡すと、時計のウィンドウはのようなタイプのtable[index, chooseColumn.Index]を最初に表示し、次にDataGridViewCheckBoxCellを表示します。私はそれがいかに可能か確かではない。

編集：私はちょうどそれが可能である方法を考え出しました。あなたは列と行のインデックスを後方に持っています。あなたの非稼働ラインは次のようになります

AGAIN

table[chooseColumn.Index, index].Value = true; //Working!!

EDIT：OK、私の以前の推測とthis answerへのリンクも必要でした。 DataBindingCompleteハンドラでインデックスの順序を修正し、セルの値をtrueに設定する必要があります。

List<Room> _value; 
    public List<Room> Value 
    { 
     get 
     { 
      List<Room> retList = new List<Room>(); 
      for (int i = 0; i < table.RowCount; i++) 
      { 
       DataGridViewCheckBoxCell cell = (DataGridViewCheckBoxCell)table[chooseColumn.Index, i]; 
       if (cell.Value != null && (bool)cell.Value) 
        retList.Add((Room)table.Rows[i].DataBoundItem); 
      } 
      return retList; 
     } 
     set 
     { 
      _value = value; 
     } 
    } 

    private void table_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e) 
    { 
     if (_value == null) return; 
     List<Room> data = (List<Room>)(table.DataSource); 
     foreach (Room room in _value) 
     { 
      int index = data.FindIndex(roomA => roomA.Id == room.Id); 
      if (index != -1) 
      { 
       table[chooseColumn.Index, index].Value = true; //Working!! 
      } 
     } 
    }
