An ImageEditor is a UITypeEditor that provides a user interface for the user to select an image for a property. When the user starts the editor, it displays an Open File dialog box that enables the user to navigate to a directory and select a file. The file list is initially filtered by the default file name extensions for the editor.

The following code example uses an EditorAttribute to associate the ImageEditor with a property.

public:
   [EditorAttribute(System::ComponentModel::Design::CollectionEditor::typeid,
      System::Drawing::Design::UITypeEditor::typeid)]
   property Image^ testImage 
   {
      Image^ get()
      {
         return testImg;
      }
      void set( Image^ value )
      {
         testImg = value;
      }
   }
private:
   Image^ testImg;
