DataGridView.AllowUserToDeleteRows Eigenschap

public:
 property bool AllowUserToDeleteRows { bool get(); void set(bool value); };

public bool AllowUserToDeleteRows { get; set; }

member this.AllowUserToDeleteRows : bool with get, set

Public Property AllowUserToDeleteRows As Boolean

Waarde van eigenschap

true als de gebruiker rijen kan verwijderen; anders, false. De standaardwaarde is true.

Voorbeelden

Het volgende codevoorbeeld illustreert het gebruik van deze eigenschap in een DataGridView besturingselement dat voornamelijk bedoeld is voor weergave. In dit voorbeeld wordt het uiterlijk van het besturingselement op verschillende manieren aangepast en wordt het besturingselement geconfigureerd voor beperkte interactiviteit. Dit voorbeeld maakt deel uit van een groter voorbeeld dat beschikbaar is in het DataGridViewCellStyle klassenoverzicht.

Opmerkingen

Als de DataGridView gegevens zijn gebonden, mag de gebruiker rijen verwijderen als zowel deze eigenschap als de IBindingList.AllowRemove eigenschap zijn ingesteld op true.
