The automatic population of an image column from a data source works with byte arrays in a variety of image formats, including all formats supported by the Image class and the OLE Picture format used by Microsoft Access and the Northwind sample database.
Populating an image column manually is useful when you want to provide the functionality of a DataGridViewButtonColumn, but with a customized appearance. You can handle the CellClick event to respond to clicks within an image cell.
Populating the cells of an image column in a handler for the CellFormatting event is useful when you want to provide images for calculated values or values in non-image formats. For example, you may have a "Risk" column with string values such as "high", "middle", and "low" that you want to display as icons. Alternately, you may have an "Image" column that contains the locations of images that must be loaded rather than the binary content of the images.
