Przygotowuje komórkę do edycji wartości.

Przeciążenia

Edit(CurrencyManager, Int32, Rectangle, Boolean)

Przygotowuje komórkę do edycji.

Edit(CurrencyManager, Int32, Rectangle, Boolean, String)

Przygotowuje komórkę do edycji przy użyciu określonego CurrencyManager, numeru wiersza i Rectangle parametrów.

Edit(CurrencyManager, Int32, Rectangle, Boolean, String, Boolean)

Edit(CurrencyManager, Int32, Rectangle, Boolean)

Przygotowuje komórkę do edycji.

override this.Edit : System.Windows.Forms.CurrencyManager * int * System.Drawing.Rectangle * bool -> unit
Protected Friend Overridable Sub Edit (source As CurrencyManager, rowNum As Integer, bounds As Rectangle, readOnly As Boolean)

Parametry

rowNum
Int32

Numer wiersza do edycji.

bounds
Rectangle

Granica Rectangle , w której ma zostać slokowana kontrolka.

readOnly
Boolean

Wartość wskazująca, czy kolumna jest tylko do odczytu. true jeśli wartość jest tylko do odczytu; w przeciwnym razie , false.

Uwagi

Edit Zazwyczaj metoda określa kontrolkę na siatce w lokalizacji edytowanej komórki.

Przykłady

W poniższym przykładzie kodu użyto Edit metody , aby zmienić tekst klikniętej komórki w kontrolce System.Windows.Forms.DataGrid .

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.
         gridCol->EditVal( myCurrencyManager, hi->Row, cellRect, false, "New Text" );
