BindingManagerBase.Position BindingManagerBase.Position BindingManagerBase.Position BindingManagerBase.Position Property

定義

派生クラスでオーバーライドされると、このデータ ソースにバインドされたコントロールが指す、基になるリストでの位置を取得または設定します。When overridden in a derived class, gets or sets the position in the underlying list that controls bound to this data source point to.

public:
 abstract property int Position { int get(); void set(int value); };
public abstract int Position { get; set; }
member this.Position : int with get, set
Public MustOverride Property Position As Integer

プロパティ値

基になるリストの中での位置を指定する、0 から始まるインデックス番号。A zero-based index that specifies a position in the underlying list.

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 に設定して、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 MoveFirst method sets the property to 0, and 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、Positionによって管理される基になるリストを反復処理するプロパティ、BindingManagerBaseします。Use the Position property to iterate through the underlying list maintained by the BindingManagerBase. 最初の項目に移動して、設定、Positionを 0 にします。To go to the first item, set the Position to 0. リストの末尾に移動して、設定、Positionの値に、Countから 1 を引いたプロパティ。To go to the end of the list, set the Position to the value of the Count property minus 1.

PositionChangedイベントが発生したときに、Positionプロパティ値が変更されます。The PositionChanged event occurs when the Position property value changes.
