Implemented by Windows Forms List Editors that support copying contents of the focused cell to the clipboard.
The Windows Forms ListViewFocusedElementToClipboardController provides the CopyCellValue Action. This Action copies the contents of the focused cell to the clipboard and is available in pop-up menus of List Editors implementing the IFocusedElementCaptionProvider interface. The interface exposes a single IFocusedElementCaptionProvider.FocusedElementCaption property. When implementing a custom Windows Forms List Editor, return the textual representation of the focused cell contents via this property.
