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

定義

派生クラスでオーバーライドされると、BindingManagerBase によって管理される行の数を取得します。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

プロパティ値

BindingManagerBase によって管理される行の数。The number of rows managed by the BindingManagerBase.

次のコードで設定を示す 4 つメソッドの例、Positionプロパティ。The following code example shows four methods that set the Position property. MoveNextメソッド、プロパティを 1 つインクリメントします。The MoveNext method increments the property by 1. MovePreviousメソッドをデクリメントを 1 つのプロパティ。The MovePrevious method decrements the property by 1. MoveFirstメソッド、プロパティを 0 に設定します。The MoveFirst method sets the property to 0. MoveLastメソッドの値にプロパティを設定する、Countから 1 を引いたプロパティ。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 'BindingManagerBase_CurrentChanged


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


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


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


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

注釈

使用して、Countによって管理される行の一覧の最後の項目を決定するプロパティ、BindingManagerBaseします。Use the Count property to determine the last item in the list of rows maintained by the BindingManagerBase. 進むには最後の項目、設定、PositionプロパティをCountから 1 を引いたプロパティの値。To go to the last item, set the Position property to the Count property value minus 1.
