Примеры

В следующем примере кода показано использование этого типа.The following code example illustrates the use of this type. Этот пример является частью большого примера, доступного в разделе как работать со столбцами изображений в элементе управления Windows Forms DataGridView.This example is part of a larger example available in How to: Work with Image Columns in the Windows Forms DataGridView Control.
