My TSRichViewEdit is placed on a TFrame,It can not update my editing result (with code) immediately As Topic.And it will scroll to the document's top after calling TSrichViewEdit.Format .I want to keep the view position after edit, Any suggestions?

Sorry, what code exactly scrolls to the top?
If Format, it is because Format moves the caret to the beginning of the document, and the editor shows the caret.

I wonder whether there is a method to update the document's content partially after editing. or I must scroll to the item manually after calling the editor format method.Thanks a lot:)

If you call editing methods, they automatically update only modified paragraphs, no need to call Format.
What editing operations do you perform?

I avoid this problem:) Thank u:)
