LoadRTFContent exception

[Matt Baker]

I'm getting the below exception when loading an RTF file from a stream.
All fonts used on the existing system (that works - not using telerik though) have been copied to the dev platform in the hope of eliminating some suspects.
If you wish I can post the RTF.
Any help appreciated.

Hi Matt,

We are not aware of this problem and you are first one to report it. However, I was unable to reproduce the problem on our side. Could you please provide more detailed information on the subject?

• Which version of RadControls for ASP.NET AJAX and .NET Framework are used in the application?
• Could you please open a support ticket and provide sample runnable project reproducing the problem containing the problematic RFT document so we can investigate it further?

Looking forward to hearing from you,
Dobromir

I have the same problem.

Dim pdfBytes As Byte() = My value in byte
Dim StreamObject As Stream = New MemoryStream(pdfBytes)
RadEditor1.LoadRtfContent(StreamObject)

My streamObject length is 14, but I have error on RadEditor1.LoadRtfContent {"Value cannot be null.\r\nParameter name: format"}.

Thank's
