    Hello!

    When you open a report in designer mode, if it is changed, then the OnSaveReport event occurs in TfrxDesigner, in which this report is edited, when the designer is closed. You can use it to write a report template to the database. 


    If the user is editing a prepared report, then this situation cannot be tracked at the moment. However, you can save the prepared report, for example, to a stream before and after editing, and then compare these streams. You can use the OnPreview and OnClosePrevies TfrxReport events to do this

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
