- SourceFormatting - The formatting of the pasted content is retained.
- MergeFormatting - The formatting of the pasted content is mostly discarded. However, emphasis formatting, such as bold and italic text, is retained when it is applied to only a portion of the selection.
- PlainText - The formatting of the pasted content and non-text elements, such as pictures or tables, is discarded.
End-users can change formatting of the pasted HTML content using buttons, which appear in the top right corner of the design area after content is pasted. By default, this functionality is disabled. Set the SettingsHtmlEditing.EnablePasteOptions property to true to enable it.
