Sobrecargas

Edit(CurrencyManager, Int32, Rectangle, Boolean)	Prepara uma célula para edição.
Edit(CurrencyManager, Int32, Rectangle, Boolean, String)	Prepara a célula para edição usando o CurrencyManager, o número da linha e os parâmetros Rectangle especificados.
Edit(CurrencyManager, Int32, Rectangle, Boolean, String, Boolean)	Quando substituído em uma classe derivada, prepara uma célula para edição.

Edit(CurrencyManager, Int32, Rectangle, Boolean)

Prepara uma célula para edição.

protected public:
 virtual void Edit(System::Windows::Forms::CurrencyManager ^ source, int rowNum, System::Drawing::Rectangle bounds, bool readOnly);

protected internal virtual void Edit (System.Windows.Forms.CurrencyManager source, int rowNum, System.Drawing.Rectangle bounds, bool readOnly);

abstract member Edit : System.Windows.Forms.CurrencyManager * int * System.Drawing.Rectangle * bool -> unit
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)

Parâmetros

source: CurrencyManager

O CurrencyManager para o DataGridColumnStyle.

rowNum: Int32

O número da linha a ser editada.

bounds: Rectangle

O Rectangle delimitador no qual o controle deve ser localizado.

readOnly: Boolean

Um valor que indica se a coluna é somente leitura. true se o valor for somente leitura; caso contrário, false.

Comentários

Normalmente, o Edit método localiza um controle na grade no local da célula que está sendo editada.

Exemplos

O exemplo de código a seguir usa o Edit método para alterar o texto de uma célula clicada no System.Windows.Forms.DataGrid controle.

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" );
      }
   }

Comentários

Normalmente, o Edit método localiza um controle na grade no local da célula que está sendo editada.
