예제

다음 코드 예제에서는 합니다 PictureBoxListView 컨트롤입니다.The following code example demonstrates the use of the PictureBox and ListView controls. PictureBox 설정 하 여 초기화 됩니다 합니다 BorderStyleSizeMode 사용 하 여 속성을 BorderStylePictureBoxSizeMode 열거형 각각.The PictureBox is initialized by setting the BorderStyle and SizeMode properties using the BorderStyle and PictureBoxSizeMode enumerations, respectively. ListView 그림 샘플 디렉터리에서 사진을 채워집니다.The ListView is populated with pictures from the Sample Pictures directory. ListView.GetItemAt 메서드를 처리할 때 사용 합니다 MouseDown 이벤트를를 ListView 항목이 선택 되어 있는지 여부를 확인 하기 위해 컨트롤.The ListView.GetItemAt method is used when handling the MouseDown event of the ListView control to determine whether an item is selected. 이벤트 처리기를 설정 하 여 선택한 파일 표시 항목을 선택 하는 경우는 Image 속성입니다.If an item is selected, the event handler displays the selected file by setting the Image property. 이 예제에서는 JPG 파일 C:\Documents and Settings\All Users\Documents\My Pictures\Sample Pictures 디렉터리에 있어야 합니다.The example requires that you have JPG files located in the C:\Documents and Settings\All Users\Documents\My Pictures\Sample Pictures directory. 예제를 실행 하려면 코드를 붙여넣고 폼을 호출 합니다 InitializePictureBoxPopulateListView 폼의 생성자에서 메서드 또는 Load 이벤트 처리 메서드.To run the example, paste the code into a form and call the InitializePictureBox and PopulateListView methods in the form's constructor or Load event-handling method. 모든 이벤트의 이벤트 처리 메서드를 사용 하 여 연결 되도록 합니다.Ensure all events are associated with their event-handling methods.
