AuthenticView.OnBeforeSave
Event: OnBeforeSave (SaveAs flag) as Boolean
Description: OnBeforeSave gives the opportunity to e.g. warn the user about overwriting the existing XML document, or to make the document read-only when specific circumstances are not met. The event will be fired before the file dialog is shown. (Please note, that the event fires when saving the XML document, and not when saving the SPS design in StyleVision.)
