WP8 - WebBrowser class : How to handle downloading of file?

[priyakankanwadi]

I have created a simple app in WP8 to display web pages using the Microsoft.Phone.Controls.WebBrowser class. I am able to load the page, navigate links, move back and forward in history. Apart from this basic functionality I also want to provide means to download files which cannot be displayed within the browser like say .ppt or .mp3.

I have not been able to find anything in the WebBrowser class documentation to initiate a download. There is just a Navigate function which takes a URL to load.

So can a download be done using WebBrowser class?

Or is there any way to automatically invoke the system viewer for the file (like powerpoint for ppt) which has been downloaded?

Hello,
No WebBrowser can't download file but here are two classes that can do it :
You can use WebClient or HttpWebRequest

WebClient

WebClient client = new WebClient();
client.OpenReadCompleted += new OpenReadCompletedEventHandler(YourMethodToGetTheFile_OpenReadCompleted);
client.OpenReadAsync(new Uri("http://www.WebSite.com/TheFile.ppt"));

HttpWebRequest

var uri = new Uri("http://www.WebSite.com/TheFile.ppt");
    HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(uri);
    request.BeginGetResponse(new AsyncCallback(YourMethodToGetTheFile_AsyncCallBack), request);

You can use one of the snippets above and then simply store the stream you get as a response in the IsolatedStorageFile
something like this for the WebClient

void YourMethodToGetTheFile_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e)
{
    var storeFile = IsolatedStorageFile.GetUserStoreForApplication();
   
    using (IsolatedStorageFileStream stream = new IsolatedStorageFileStream("TheFile.ppt", System.IO.FileMode.Create, storeFile ))
    {
        byte[] buffer = new byte[1024];
        while (e.Result.Read(buffer, 0, buffer.Length) > 0)
        {
            stream.Write(buffer, 0, buffer.Length);
        }
    }
}

Don't forget to delete the file if exist in the IsolatedStorage, I didn't handle it in the example.
