BindingManagerBase.Count Properti

Definisi

Ruang nama:

System.Windows.Forms

Rakitan:

System.Windows.Forms.dll

Sumber:

BindingManagerBase.cs

Ketika ditimpa dalam kelas turunan, mendapatkan jumlah baris yang dikelola oleh BindingManagerBase.

public:
 abstract property int Count { int get(); };

public abstract int Count { get; }

member this.Count : int

Public MustOverride ReadOnly Property Count As Integer

Nilai Properti

Int32

Jumlah baris yang dikelola oleh BindingManagerBase.

Contoh

Contoh kode berikut menunjukkan empat metode yang mengatur Position properti . Metode ini MoveNext menaikkan properti sebesar 1. Metode MovePrevious ini mengurangi properti sebesar 1. Metode MoveFirst mengatur properti ke 0. Metode MoveLast mengatur properti ke nilai Count properti dikurangi 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

Keterangan

Count Gunakan properti untuk menentukan item terakhir dalam daftar baris yang dikelola oleh BindingManagerBase. Untuk masuk ke item terakhir, atur Position properti ke Count nilai properti dikurangi 1.
