예제

다음 코드 예제는 SelectedItems, SelectedIndexChanged 이벤트 및 HeaderStyle 멤버 및 ListView.SelectedListViewItemCollection 클래스.The following code example demonstrates using the SelectedItems, SelectedIndexChanged event, and HeaderStyle members and the ListView.SelectedListViewItemCollection class. 이 예제를 실행 하려면 포함 된 폼에서 다음 코드를 붙여 넣습니다를 ListView 개체인 ListView1TextBox 라는 TextBox1합니다.To run this example, paste the following code in a form that contains a ListView object named ListView1 and a TextBox named TextBox1. 호출 된 InitializeListView 폼의 생성자에서 메서드 또는 Load 이벤트 처리기입니다.Call the InitializeListView method from the form's constructor or the Load event handler. 이 예제에서는 이벤트 처리기와 올바르게 연결 된 SelectedIndexChanged 이벤트This example requires that the event handler is correctly associated with the SelectedIndexChanged event

// This method adds two columns to the ListView, setting the Text 
// and TextAlign, and Width properties of each ColumnHeader.  The

// event is not handled.  Finally the method adds ListViewItems and 
// SubItems to each column.
