BindingManagerBase.Count Propriété

Définition

Espace de noms:

System.Windows.Forms

Assembly:

System.Windows.Forms.dll

En cas de substitution dans une classe dérivée, obtient le nombre de lignes managées par 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

Int32

Nombre de lignes managées par BindingManagerBase.

Exemples

L’exemple de code suivant montre quatre méthodes qui définissent la Position propriété. La MoveNext méthode incrémente la propriété de 1. La MovePrevious méthode décrémente la propriété par 1. La MoveFirst méthode définit la propriété sur 0. La MoveLast méthode définit la propriété sur la valeur de la Count propriété moins 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 le BindingManagerBase. Pour accéder au dernier élément, définissez la Position propriété sur la Count valeur de propriété moins 1.
