TOPIC:

when i ran the windows app certification kit i got certain errors, i am attaching them, please see that.

Make sure that you are using the release builds with both projects, check the screenshot..

You can hit this error if your build runs the WACK tools against DEBUG builds as a custom step or you don’t have the .NET Native toolchain enabled for your RELEASE builds.

If you still have problems, can you send us more details about your configurations?

Thanks a lot for the information nermeen, I want to know how do you refresh the loaded pdfviewer on canvas, i.e when I remove a page from file I need to refresh the view to preview the changes

Thanks.

For such a modification You can do like the following:

For a smaller modification, like adding/deleting/editing an anootation you can use, m_view.vRenderAsync or m_view.vRenderSync

I tried your suggestion but the issue is after the removal I need to scroll the pdf pages down & again up to see the changes , is there a way to reflect the change quickly (some thing like reloading...)?

Thanks

m_doc.RemovePage(pageno);
m_view.vZoom(m_view.vGetScale());

The above code is working in the demo project, without the need to scroll..
To reload, you need to save the doc, close and then reopen...check the below code in PDFReaderPage.xaml.cs

m_doc.Save();
vClose();
