Loading Documents from the Web

To load a file from the Web you must first download it to your application using an asynchronous request object such as HttpClient. Then you simply pass the resulting stream to the LoadDocument method or LoadDocumentAsync method. The following code snippet example uses an HTTP request:

C#	Copy Code
private async void LoadDocument() { // load file from the Web HttpClient client = new HttpClient(); string url = “http://cdn.componentone.com/files/win8/Win8_UXG_RTM.pdf”; try { var stream = await client.GetStreamAsync(new Uri(url, UriKind.Absolute)); pdfViewer.LoadDocument(stream); } catch { var dialog = new MessageDialog("There was an error attempting to download the document."); dialog.ShowAsync(); } }

Copy Code

private async void LoadDocument()
{
     // load file from the Web
     HttpClient client = new HttpClient();
     string url = “http://cdn.componentone.com/files/win8/Win8_UXG_RTM.pdf”;
    
    try
    {
       var stream = await client.GetStreamAsync(new Uri(url, UriKind.Absolute));
       pdfViewer.LoadDocument(stream);
    }
    catch
    {
       var dialog = new MessageDialog("There was an error attempting to download the document.");
       dialog.ShowAsync();
    }
}
