BindingManagerBase.Count BindingManagerBase.Count BindingManagerBase.Count BindingManagerBase.Count Property

Définition

En cas de substitution dans une classe dérivée, obtient le nombre de lignes managées par BindingManagerBase.When overridden in a derived class, gets the number of rows managed by the BindingManagerBase.

public:
 abstract property int Count { int get(); };
public abstract int Count { get; }
member this.Count : int
Public MustOverride ReadOnly Property Count As Integer

Valeur de propriété

Nombre de lignes managées par BindingManagerBase.The number of rows managed by the BindingManagerBase.

Exemples

L’exemple de code suivant illustre quatre méthodes qui définissent la Position propriété.The following code example shows four methods that set the Position property. La MoveNext méthode incrémente la propriété de 1.The MoveNext method increments the property by 1. La MovePrevious méthode décrémente la propriété de 1.The MovePrevious method decrements the property by 1. La MoveFirst méthode affecte la valeur 0 à la propriété.The MoveFirst method sets the property to 0. La MoveLast méthode affecte à la propriété la valeur de la Count propriété moins 1.The MoveLast method sets the property to the value of the Count property minus 1.

private:
   void BindingManagerBase_CurrentChanged( Object^ sender, EventArgs^ /*e*/ )
   {
      // Print the new value of the current object.
      Console::Write( "Current Changed: " );
      Console::WriteLine( ( (BindingManagerBase^)(sender) )->Current );
   }

   void MoveNext()
   {
      // Increment the Position property value by one.
      myBindingManagerBase->Position = myBindingManagerBase->Position + 1;
   }

   void MovePrevious()
   {
      // Decrement the Position property value by one.
      myBindingManagerBase->Position = myBindingManagerBase->Position - 1;
   }

   void MoveFirst()
   {
      // Go to the first item in the list.
      myBindingManagerBase->Position = 0;
   }

   void MoveLast()
   {
      // Go to the last row in the list.
      myBindingManagerBase->Position = myBindingManagerBase->Count - 1;
   }
private void BindingManagerBase_CurrentChanged
(object sender, EventArgs e)
{
   // Print the new value of the current object.
   Console.Write("Current Changed: ");
   Console.WriteLine(((BindingManagerBase)sender).Current);
}

private void MoveNext()
{
   // Increment the Position property value by one.
   myBindingManagerBase.Position += 1;
}

private void MovePrevious()
{
   // Decrement the Position property value by one.
   myBindingManagerBase.Position -= 1;
}

private void MoveFirst()
{
   // Go to the first item in the list.
   myBindingManagerBase.Position = 0;
}

private void MoveLast()
{
   // Go to the last row in the list.
   myBindingManagerBase.Position = 
   myBindingManagerBase.Count - 1;
}
   
Private Sub BindingManagerBase_CurrentChanged(sender As Object, e As EventArgs)
    ' Print the new value of the current object.
    Console.Write("Current Changed: ")
    Console.WriteLine(CType(sender, BindingManagerBase).Current)
End Sub


Private Sub MoveNext()
    ' Increment the Position property value by one.
    myBindingManagerBase.Position += 1
End Sub


Private Sub MovePrevious()
    ' Decrement the Position property value by one.
    myBindingManagerBase.Position -= 1
End Sub


Private Sub MoveFirst()
    ' Go to the first item in the list.
    myBindingManagerBase.Position = 0
End Sub


Private Sub MoveLast()
    ' Go to the last row in the list.
    myBindingManagerBase.Position = myBindingManagerBase.Count - 1
End Sub

Remarques

Utilisez la Count propriété pour déterminer le dernier élément de la liste des lignes gérées par BindingManagerBasele.Use the Count property to determine the last item in the list of rows maintained by the BindingManagerBase. Pour atteindre le dernier élément, affectez à Position la propriété la Count valeur de la propriété moins 1.To go to the last item, set the Position property to the Count property value minus 1.
