Přetížení

Edit(CurrencyManager, Int32, Rectangle, Boolean)

Připraví buňku pro úpravy.Prepares a cell for editing.

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

Připraví buňku pro úpravy pomocí zadaného CurrencyManager , čísla řádku a Rectangle parametrů.Prepares the cell for editing using the specified CurrencyManager, row number, and Rectangle parameters.

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

Při přepsání v odvozené třídě připraví buňku pro úpravy.When overridden in a deriving class, prepares a cell for editing.

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

Parametry

rowNum
Int32

Číslo řádku, které chcete upravit.The row number to edit.

bounds
Rectangle

Rozsah, Rectangle ve kterém má být ovládací prvek umístěn.The bounding Rectangle in which the control is to be sited.

readOnly
Boolean

Hodnota, která označuje, zda je sloupec jen pro čtení.A value indicating whether the column is a read-only. true Pokud je hodnota jen pro čtení; v opačném případě false .true if the value is read-only; otherwise, false.

Poznámky

Metoda obvykle vydává Edit ovládací prvek do mřížky v umístění upravované buňky.Typically, the Edit method sites a control onto the grid at the location of the cell being edited.

Příklady

Následující příklad kódu používá Edit metodu ke změně textu kliknutím na buňku v System.Windows.Forms.DataGrid ovládacím prvku.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.

      }
   }
