How to bind a RichEditControl to a data field that contains plain and RTF text

created 5 years ago

Good Morning,

I am using your RichEditControl bound to a varchar max field of a SQL Server database and it is working great. The texts are stored into the field correctly and loading of the field content back into the RichEditControl is working fine as well.

Unfortunately the database table is not brand new and old records exists where the same field is used to store plain texts - so basically the contents are unformatted notes. In case a users selects one of the old records to be loaded into the RichEditControl the value of the RichEditControl stays empty.

Is there a work around you suggest to be able to open the old records with plain text in the RichEditControl as well? Or should I stop using the
same field to store "legacy" plain text and new RTF text and instead kind of "import" the plain text into the RichEditControl if I figure out
that that the record opened by the user ist "legacy" plain text record?

Thank you for your advice,

Sven

Hello Sven,

You can use our IFormatDetectorService service to determine if a data record has RTF data. Convert data from a database to a memory stream to load it to the IFormatDetectorService.DetectFormat method.

Alternatively, you can check if a string from the database starts with the "{\rtf1" prefix. If so, this string contains RTF data.

      I created a sample that demonstrates how to bind a data object to the RichEditControl.RtfText property and convert plain text to RTF using our non-visual RichEditDocumentServer component. You can find the project and video in the attachment.
