Only a suggestion that the effect on copying to the clipboard can be set directly in e.Style.DoubleEdit. ... not by means of an event.
gridControl.Model.ClipboardCanCopy + = new GridCutPasteEventHandler (Model_ClipboardCanCopy);
The format of this copy = to make it easy to set, to copy what you see. e.g. e.Style.DoubleEdit.CopyOptions = "Visual" the same with data export
unless you can do it simpler?
