'宣言 Public Property ExpansionIndicator As ShowExpansionIndicator
public ShowExpansionIndicator ExpansionIndicator {get; set;}
このプロパティは、子行を持たない行の展開インジケーターを表示するかどうか、または子行を持つ行の展開インジケーターを非表示にするかどうかを決定します。
Expanded プロパティを使用すると、展開インジケーターを展開 (マイナス) と縮小 (プラス) のどちらの状態にするかを指定できます。
ユーザーが展開インジケーターをクリックして行を展開または縮小すると、BeforeRowExpanded イベントと BeforeRowCollapsed イベントが生成されます。
