Примеры

В следующем примере кода создается объект TabControl с двумя TabPage объектами, каждый из которых содержит один Button компонент.The following code example creates a TabControl with two TabPage objects, each containing one Button component. Параметр button2 передается в GetTabPageOfComponent метод, который извлекает TabPage содержащий button2 .The parameter button2 is passed to the GetTabPageOfComponent method, which retrieves the TabPage containing button2. Чтобы убедиться в том, что получена правильная страница вкладки, SelectedIndex свойство задает TabPage страницу, содержащуюся в button2 текущей выбранной вкладке.To verify that the correct tab page is retrieved, the SelectedIndex property sets the TabPage containing button2 to the currently selected tab page.
