ImageList se utiliza normalmente por otros controles, como el ListView, TreeView, o ToolBar.ImageList is typically used by other controls, such as the ListView, TreeView, or ToolBar. Puede agregar mapas de bits o iconos a la ImageList, y los demás controles pueden utilizar las imágenes que necesiten.You can add bitmaps or icons to the ImageList, and the other controls are able to use the images as they require.

ImageList utiliza un identificador para administrar la lista de imágenes.ImageList uses a handle to manage the list of images. El Handle no se crea hasta que ciertas operaciones, como obtener el Handle o llamar a Draw, se realizan en la lista de imágenes.The Handle is not created until certain operations, such as getting the Handle or calling Draw, are performed on the image list. Realizar otras operaciones, como establecer el ColorDepth o ImageSize hará que el Handle volver a crear.Performing other operations, such as setting the ColorDepth or ImageSize will cause the Handle to be recreated. Por lo tanto, debe realizar estas operaciones antes de agregar imágenes a la ImageList.Therefore, you should perform these operations before you add images to the ImageList. Además, cuando se trabaja con los formularios que se traducirá, deberá agregar siempre una ImageList e imágenes cuando la propiedad de idioma de un formulario se establece en predeterminado.In addition, when you work with forms that will be localized, you should always add an ImageList and images when the Language property of a form is set to Default. Cambiar el idioma del formulario antes de agregar imágenes dañará los archivos de recursos de la aplicación.Changing the form's language before you add images will corrupt the application resource files.
