Export Rad Report as Rtf as byte and import to RadRichTextBox

[Abolhassan]

I'm implementing a wpf application with rad control 2014 to export radreport to Rtf and save as byte to database then retrieve the data from database and display in RadRichTextBox.

here's my code:

Export to rtf format and save to database

System.Collections.Hashtable deviceInfo = new System.Collections.Hashtable();
Telerik.Reporting.TypeReportSource typeReportSource = new Telerik.Reporting.TypeReportSource();

 Telerik.Reporting.Processing.ReportProcessor reportProcessor = new Telerik.Reporting.Processing.ReportProcessor();
Telerik.Reporting.InstanceReportSource instanceReportSource = new Telerik.Reporting.InstanceReportSource();
instanceReportSource.ReportDocument = report;
Telerik.Reporting.Processing.RenderingResult renderedReport = reportProcessor.RenderReport("RTF", instanceReportSource, null);

and save the output of renderedReport.DocumentBytes to database. 

Load the byte[] and bind to RadRichTextBox

RadDocument document = null;
IDocumentFormatProvider provider = new RtfFormatProvider();
using (Stream stream = new MemoryStream(viewDocumentsCore.DocumentContent))
{
    document = provider.Import(stream);
}

radRichTextBox.Document = document;

But it causes error.

I would appreciate for any help.
