RefreshSortPosition メソッド (UltraGridGroupByRow)

行が正しいソート位置にない場合に、現在のソート順に従って行コレクション内の行の位置を再調整します。

シンタックス

Visual Basic

'宣言
 
Public Overrides NotOverridable Sub RefreshSortPosition() 

C#

public override void RefreshSortPosition()

解説

このメソッドは、新しい行を行コレクションに追加するときに、コレクション全体を並べ替え直さずに、その行を並べ替え基準に基づくコレクション内の適正な位置に配置する場合に役立ちます (デフォルトでは、新しい行は行コレクションの末尾に追加されます)。このメソッドは、並べ替え基準自体が変更され、その変更が行コレクション全体に影響する場合には、使用しないでください。
