The DevExpress ASP.NET HTML Editor (ASPxHtmlEditor) can automatically format pasted HTML content based on its PasteMode property - which can be set using one of the following values:
- SourceFormatting: Formatting of pasted content is retained.
- MergeFormatting: Formatting of pasted content is mostly discarded. However, emphasis formatting, such as bold and italic text, is retained.
- PlainText: Formatting of pasted content and non-text elements (such as pictures or tables) is discarded.
End-users can change formatting of pasted HTML content using the buttons that appear in the top right corner of the design area once content is pasted. By default, this functionality is disabled. Set the EnablePasteOptions property to true to enable it.
You can also format pasted HTML content in code using the client-side BeforePaste event. To explore this functionality, review the Manual Paste Formatting demo.
