The event handler receives an argument of type System.EventArgs containing data related to this event.
The DocumentLoaded event fires after the LoadDocument method is executed when the document model is built and the loaded document is valid.
Handle the DocumentLoaded event to ensure that the document is loaded completely so you can safely modify it.
NoteWhen an HTML document with external image references is loaded, the images are obtained asynchronously and the DocumentLoaded event cannot guarantee image availability at the moment it is raised. The RichEditControl does not provide a technique that allows you to determine the moment when all images are downloaded and inserted in a document.
