Hello,

Thank you for your further feedback.
You need to reference Spire.Pdf.Asp.dll, Spire.License.dll, and Spire.PdfViewer.Asp.dll from same floder( ASP.NET4.0, according to target framework), also Spire.Pdf.dll and Spire.Doc.dll from same floder( NET4.0).

Thanks again for your immediate response.
Hope this one be my last question: Do i have the opporunity to load file in pdfViewer directly from server instead of cache. Is there any piece of code i could add in LoadFromFile function?
Thanks in advance once again

Hi,

My testing code,

Thanks again. Code works fine but for a large pdf file (lets say 40 pages), pdfViewer shows only a few of them (No more than five).
Rest of them are blank. This might be a viewer issue
Thanks again for help

Dear Caroline, i tested with different pdf files, so i suppose it is not a matter of specific pdf file. Problem appears for pdf files with above 40 pages.
As for the code i try to load it as stream using the code you provided above.

Sincerely,
Dimitris

Dear Caroline
I saw some new versions on dll Files, about pdf Viewer. However using these new files didn't fix the problem.
Thanks!

Thanks for your response

I use both Firefox and Google for testing purposes but the problem remains the same.
As for the version of Spire.PdfViewer.Asp.dll is 2.10.17.4340 (The one that is included in the new HotFix Version) the one that was published on 23/08/2016

I use IE11.
Sorry but i cannot attach some screenshot. The problem appears when i try to display a pdf file on pdfViewer which is larger than 10 pages. The first 5 pages are displayed, but the rest of them cannot be loaded and i only see a cyrcle process Bar.

Thanks and sorry about the inconvinience

Dear darmenakis,

I suppose that you didn't use the property IsPostBack. Please use it and check the result.
Here is sample code for your reference.
Code: Select all
            //this is the thing must do in ASP.NET
            if (!IsPostBack)
            {
                byte[] data = File.ReadAllBytes(@"D:\download\Pv-204.pdf");
                MemoryStream pdfStream = new MemoryStream(data);
                PdfViewer1.LoadFromStream(pdfStream);
            }

If there is still issue, please provide us the sample file and code you were using to help us do an investigation.

Sincerely,
Betsy
