BindingManagerBase.Count Propriété

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 propriété Position.The following code example shows four methods that set the Position property. La méthode MoveNext incrémente la propriété de 1.The MoveNext method increments the property by 1. La méthode MovePrevious décrémente la propriété de 1.The MovePrevious method decrements the property by 1. La méthode MoveFirst affecte la valeur 0 à la propriété.The MoveFirst method sets the property to 0. La méthode MoveLast affecte à la propriété la valeur de la propriété Count 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 propriété Count pour déterminer le dernier élément de la liste des lignes gérées par le BindingManagerBase.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 la propriété Position la valeur de la propriété Count moins 1.To go to the last item, set the Position property to the Count property value minus 1.
