Asked On May 27, 2013 02:26 PM UTC

Hi,

I'm trying to display simply a PDF document with SfPdfViewerControl,

but LoadDocument method throws an exception and I don't know why, because I just copied and pasted the example from sample.

Here's my code:

var picker = new FileOpenPicker();
                                    picker.SuggestedStartLocation = PickerLocationId.DocumentsLibrary;
                                    picker.ViewMode = PickerViewMode.List;
                                    picker.FileTypeFilter.Add(".pdf");
                                    var filetest = await picker.PickSingleFileAsync();
                                    var stream = await filetest.OpenAsync(Windows.Storage.FileAccessMode.Read);
                                    Stream fileStream = stream.AsStreamForRead();
                                    byte[] buffer = new byte[fileStream.Length];
                                    fileStream.Read(buffer, 0, buffer.Length);
                                    PdfLoadedDocument ldoc = new PdfLoadedDocument(buffer);
                                    await pdfViewer.LoadDocumentAsync(ldoc);  // Here is thrown an exception


The thrown exception's message is:

Object reference not set to an instance of an object.


Could somebody help me to find the solution?

Thanks very much.

Hi Oh,

 

Thank you for your interest in Syncfusion products.

 

We are not able to reproduce the issue “Null reference exception is thrown when using LoadDocumentAsync method”. We tried with the sample available in the link below, but threading exception occurs in the Viewer when using LoadDocumentAsync method. We have logged an issue report for fixing this issue, the fix for this issue will be available in our upcoming release.

 

Sample Link: GappTestPdfViewer_LoadAsync.zip

 

Please let us know if you have any concerns.

 

Thanks,

Hi Suresh,
Thanks for your help. Can you tell me how to upgrade our syncfusion winrt? I already have purchased this.
And again thanks  for given me a sample for display image in word and excel document.

And I have one more question for you. In my another app I am using
     <editors:TextBoxExt  x:Name="cmb_AC_ID" SearchItemPath="AC_ID" SuggestionPopupClosed="cmb_AC_ID_SuggestionPopupClosed"
 Watermark="" FontSize="13"  SuggestionMode="StartsWith"  AutoCompleteMode="Suggest"/>
In this control, when I open this page in edit mode, This control filled with value but that seems to get stuck in the ON position.
I have attached a screenshot for you better understanding.pls find attachment. see Aircraft Type field in this screenshot.

Hi Sandeep,

 

Thank you for your reponse,

 

Regarding Upgradation:

 

Whenever you upgrade to newer version it is not necessary to uninstall the older version because Syncfusion supports multiple versions to be installed in the same machine. So, you can install the latest version Essential Studio WINRT(XAML) setup with the respective version unlock key as you wish.

 

Regarding issue with SfTextBoxExt control

 

We are unable to reproduce the reported SfTextBoxExt gets stuck in the ON position issue. Please find the sample used for replication from the following location,

 

http://www.syncfusion.com/downloads/Support/DirectTrac/General/AutoCompleteSample-743188818.zip

 

Please modify the sample to reproduce the issue or provide us more information to assist you further with accurate solution.

 

Please let us know if you have any concerns.

 

Thanks,

Suresh
