注意 (継承者)

からDataGridViewImageColumn派生し、派生クラスに新しいプロパティを追加する場合は、複製操作中Clone()に新しいプロパティをコピーするようにメソッドをオーバーライドしてください。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. また、基本クラスのClone()メソッドを呼び出して、基底クラスのプロパティが新しいセルにコピーされるようにする必要があります。You should also call the base class's Clone() method so that the properties of the base class are copied to the new cell.
