DataGridViewCell.EditedFormattedValue Propriété

Définition

Obtient la valeur actuelle mise en forme de la cellule, que la cellule soit en mode édition ou non et que la valeur ait été validée ou non.Gets the current, formatted value of the cell, regardless of whether the cell is in edit mode and the value has not been committed.

Valeur de propriété

Valeur actuelle mise en forme de DataGridViewCell.The current, formatted value of the DataGridViewCell.

Attributs

Exceptions

La ligne qui contient la cellule est une ligne partagée.The row containing the cell is a shared row.

-ou--or-

La cellule est une cellule d'en-tête de colonne.The cell is a column header cell.

ColumnIndex est inférieur à 0, ce qui indique que la cellule est une cellule d'en-tête de ligne.ColumnIndex is less than 0, indicating that the cell is a row header cell.

La mise en forme a échoué et soit il n'y a aucun gestionnaire pour l'événement DataError du contrôle DataGridView, soit le gestionnaire a affecté ThrowException à la propriété true.Formatting failed and either there is no handler for the DataError event of the DataGridView control or the handler set the ThrowException property to true. L’objet exception peut généralement être converti en type FormatException.The exception object can typically be cast to type FormatException.

Exemples

L’exemple de code suivant montre comment utiliser la propriété EditedFormattedValue.The following code example demonstrates how to use the EditedFormattedValue property. Dans cet exemple, la propriété IsCurrentCellDirty est utilisée pour déterminer si le contenu de la cellule active a été modifié et non validé et, si la cellule a été modifiée, la valeur modifiée est utilisée.In this example, the IsCurrentCellDirty property is used to determine if the current cell's contents have been edited and not committed and, if the cell has been modified, the edited value is used. Cet exemple fait partie d’un exemple plus complet disponible dans l’événement DataGridView.SelectionChanged.This example is part of a larger example available in the DataGridView.SelectionChanged event.

Remarques

Cette propriété retourne la valeur actuelle de la cellule ou du contrôle d’édition si la cellule est en mode édition.This property returns the current value of the cell or editing control if the cell is in edit mode. Sinon, l’obtention de la valeur de cette propriété convertit la valeur de la cellule en une valeur d’affichage équivalente du type indiqué par la propriété FormattedValueType.Otherwise, getting the value of this property converts the cell value into an equivalent display value of the type indicated by the FormattedValueType property. Cela déclenche l’événement DataGridView.CellFormatting, que vous pouvez gérer pour personnaliser la conversion de valeur.This raises the DataGridView.CellFormatting event, which you can handle to customize the value conversion.

Si la mise en forme échoue, l’événement DataGridView.DataError se produit.If formatting is unsuccessful, the DataGridView.DataError event occurs. S’il n’existe aucun gestionnaire pour cet événement ou si le gestionnaire affecte la valeur trueà la propriété DataGridViewDataErrorEventArgs.ThrowException, une exception est levée.If there is no handler for this event or the handler sets the DataGridViewDataErrorEventArgs.ThrowException property to true, an exception is thrown.
