- Int32
Numéro de la ligne à modifier.
- readOnly
- Boolean
Valeur indiquant si la colonne est en lecture seule. true
si la valeur est en lecture seule ; sinon, false

Remarques
En règle générale, la Edit méthode place un contrôle sur la grille à l’emplacement de la cellule en cours de modification.

Exemples
L’exemple de code suivant utilise la Edit méthode pour modifier le texte d’une cellule cliquée dans le System.Windows.Forms.DataGrid contrôle.
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" );
}
}
