Remarks
The DataGridViewImageColumn class is a specialized type of the DataGridViewColumn class used to logically host cells that display images. A DataGridViewImageColumn has an associated DataGridViewImageCell in every DataGridViewRow that intersects it. Each cell is capable of containing an Image or an Icon, depending on the value of the DataGridViewImageCell.ValueIsIcon property. Displaying icons is useful to accommodate images with transparency.
By default, empty cells display a default error graphic. To prevent this graphic from appearing for cell values equal to null or DBNull.Value, set the DataGridViewCellStyle.NullValue property of the cell style object returned by the DefaultCellStyle property to null before adding rows to the control. This does not affect the row for new records, however. To prevent the error graphic from appearing in the row for new records when the control AllowUserToAddRows property value is true, you must also either explicitly set the cell value to null in a handler for the control RowsAdded event or set the column CellTemplate property to an instance of a DataGridViewImageCell-derived type with an overridden DefaultNewRowValue property that returns null.
The default sort mode for this column type is NotSortable.
Notes to Inheritors
When you derive from DataGridViewImageColumn and add new properties to the derived class, be sure to override the Clone() method to copy the new properties during cloning operations. You should also call the base class's Clone() method so that the properties of the base class are copied to the new cell.
