Now the problem become more complex.
Some pdf files can be opened, and some files can't.
All pdf files are generated by iTextSharp 5.4.3

Below are 2 sample files:
Can be opened.
Can't be opened.

Any comment will be appreciated.

Hello Sandhiya,

Thank you for contacting us!
The first document (DO13080002.pdf) is loaded correctly, but the second one (DO13080003.pdf) is not.
We will need to investigate this issue further.

If you have any other questions or concerns, please do not hesitate to contact us again!

Hi Alexander,

I have opened support ticket (#731428).
In there, I already submit 2 similar pdf files.
1 file has table with borders (loaded correctly), the other 1 file has table without borders (failed to be loaded).
All the contents between that 2 files are 100% same.
So I think the issue is with table borders.

Hi,

Actually, the problem with the files you provided is that they do not end with %%EOF marker. This marker is required for RadPdfViewer to work correctly. If you open your files with any text editor (Notepad for example), you will find that your document ends with a lot of null bytes. RadPdfViewer is designed to search for %%EOF marker in the last 1024 bytes. If it does not find one, the document will not be displayed at all. You will need to trim those null bytes in order to open the documents in RadPdfViewer.

More information about this can be found in this help article.

Let us know if you have further questions.

Hi Kammen, thank you for pointing this out.
You are right, we use wrong method when converting from MemoryStream to byte[]
We use .GetBuffer() instead of .ToArray()
And we also don't realize there are so many trailing nulls in the pdf file.
