名前	説明
Edit(CurrencyManager, Int32, Rectangle, Boolean)	セルを編集用に準備します。
Edit(CurrencyManager, Int32, Rectangle, Boolean, String)	指定した CurrencyManager、行番号、および Rectangle パラメーターを使用して、編集用のセルを準備します。

Protected Friend Overridable Sub Edit (source As CurrencyManager, rowNum As Integer, bounds As Rectangle, readOnly As Boolean)

パラメーター

source: CurrencyManager

CurrencyManagerの DataGridColumnStyle。

rowNum: Int32

編集する行番号。

bounds: Rectangle

コントロールがサイト化される境界 Rectangle 。

readOnly: Boolean

列が読み取り専用かどうかを示す値。 true 値が読み取り専用の場合。それ以外の場合は false。

注釈

通常、 Edit メソッドは、編集中のセルの位置にコントロールをグリッド上に配置します。

例

次のコード例では、Edit メソッドを使用して、System.Windows.Forms.DataGrid コントロール内のクリックされたセルのテキストを変更します。

public ref class Form1: public Form
{
private:
   DataSet^ myDataSet;
   void dataGrid1_MouseDown( Object^ sender, MouseEventArgs^ e )
   {
      // Use the HitTest method to get a HitTestInfo object.
      System::Windows::Forms::DataGrid::HitTestInfo^ hi;
      DataGrid^ grid = dynamic_cast<DataGrid^>(sender);
      hi = grid->HitTest( e->X, e->Y );

      // Test if the clicked area was a cell.
      if ( hi->Type == DataGrid::HitTestType::Cell )
      {
         // If it's a cell, get the GridTable and CurrencyManager of the
         // clicked table.         
         DataGridTableStyle^ dgt = grid->TableStyles[ 0 ];
         CurrencyManager^ myCurrencyManager = dynamic_cast<CurrencyManager^>(this->BindingContext[ myDataSet->Tables[ dgt->MappingName ] ]);

         // Get the Rectangle of the clicked cell.
         Rectangle cellRect;
         cellRect = grid->GetCellBounds( hi->Row, hi->Column );

         // Get the clicked DataGridTextBoxColumn.
         MyColumnStyle ^ gridCol = dynamic_cast<MyColumnStyle^>(dgt->GridColumnStyles[ hi->Column ]);

         // Edit the value.
