Hi Dimitar,

To create the document I am using a RadRichTextBox. I change the document to format as two columns and add a header that contains text and our company logo image. I save the document to our database as a string by using the XamlFormatProvider. In a different area in our program I then get that string from the database and use the XamlFormatProvider to import the string which gives me the RadDocument. I then convert the RadDocument into a PDF using the PdfFormatProvider. The error that is given is during the export function on the PdfFormatProvider.

As a note when I load the document back into my RadRichTextBox the document loads and displays just fine.

Please let me know if I can help getting this resolved in any way.

Thank you

Hello Ashley,

We have further investigated this and I wanted to ask you the exact steps for creating such a document? This will allow me to determine what is causing the invalid value.

I am looking forward to your reply.

Hello! I really really need this functionality fixed as soon as possible. My client formats their document in two columns to fit as much on the page as possible to send to vendors.
