When you create a custom text element, you can use the IsMergeable and IsTypographicOnly properties are set to false, a RichTextBox preserves the boundaries and content of the element when the user edits the RichTextBox. In general, the custom element behaves similar to a Hyperlink. The following behavior occurs when you use this class and set both of its properties to false:attribute to specify that the element should be treated as a single, unbreakable entity. When the
When a user copies and pastes a part of the content in a custom element, the formatting of the copied text is not preserved.
When a user types before or after the content of the custom element, the new content does not acquire the custom element's formatting information.
The user cannot insert a line break in the custom element.
When you create a custom element, use the TextRange.Save(Stream, String, Boolean) method and set preserveTextElements to true to preserve the custom element and property values when you serialize it to the disk or clipboard.
