Parameter

rowNum
Int32 Int32 Int32 Int32

Die Nummer der zu bearbeitenden Zeile.The row number to edit.

bounds
Rectangle Rectangle Rectangle Rectangle

Das umschließende Rectangle, in dem das Steuerelement positioniert werden soll.The bounding Rectangle in which the control is to be sited.

readOnly
Boolean Boolean Boolean Boolean

Ein Wert, der angibt, ob die Spalte schreibgeschützt ist.A value indicating whether the column is a read-only. true, wenn der Wert schreibgeschützt ist, andernfalls false.true if the value is read-only; otherwise, false.

Beispiele

Im folgenden Codebeispiel wird die Edit -Methode verwendet, um den Text einer geklickten System.Windows.Forms.DataGrid Zelle im-Steuerelement zu ändern.The following code example uses the Edit method to change the text of a clicked cell in the System.Windows.Forms.DataGrid control.

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.
