This document is a brief overview of events implemented in the RichEditControl.
When a document is loaded in RichEditControl, the RichEditControl.DocumentClosing event occurs. It enables you to take the necessary steps before the content of the previously loaded document is discarded. Then the RichEditControl.BeforeImport event is raised, enabling you to configure the importer, and the RichEditControl.DocumentLoaded event indicates that the loading process is finalized.
The RichEditControl.ContentChanged event indicates changes in the control content, while the RichEditControl.ModifiedChanged event occurs when the current document is modified and the RichEditControl.Modified property is changed. The ModifiedChanged event is not raised when a document is loaded or saved.
If the loaded document contains fields and RichEditMailMergeOptions.ViewMergedData is set to true, the fields are automatically updated and the ModifiedChanged event fires.
When a document is saved, the RichEditControl.BeforeExport event occurs, enabling you to customize export settings (e.g., specify the location to store external content when the document is saved in HTML).
A special RichEditControl.UnhandledException event provides an easy-to-use method for processing exceptions that are not handled by RichEditControl.
Some events are implemented to allow the customization of RichEditControl. The RichEditControl.PopupMenuShowing event allows you to modify a popup menu before it is shown.
The mail merge process is also accompanied by events - RichEditControl.MailMergeStarted, RichEditControl.MailMergeRecordStarted, RichEditControl.MailMergeRecordFinished and RichEditControl.MailMergeFinished.
