Unable to share image using DataTransferManager in Windows 10

Question

Requirement: Share a text and image using DataTransferManager into Facebook in Windows 10.

Problem: Unable to share image.

Below shown is the code I used,

 private async void DataTransferManager_DataRequested(DataTransferManager sender, DataRequestedEventArgs args)
        {
            DataRequestDeferral deferral = args.Request.GetDeferral();
            args.Request.Data.Properties.Title = "Sharing sample";
            args.Request.Data.SetText("Testing share in universal app");
            var imageUri = "http://cdn.vrworld.com/wp-content/uploads/2015/01/microsoft-announces-windows-10_ahab.1920.jpg";

            //var storageFile = await StorageFile.CreateStreamedFileFromUriAsync("ShareFile", new Uri(imageUri), null);
            //List<IStorageItem> storageItems = new List<IStorageItem>();
            //storageItems.Add(storageFile);
            //args.Request.Data.SetStorageItems(storageItems);

            args.Request.Data.SetBitmap(Windows.Storage.Streams.RandomAccessStreamReference.CreateFromUri(new Uri(imageUri)));
            deferral.Complete();
        }

When I use SetBitmap method, only the title and text are being shared. The image is neither displayed in the share panel nor shared to the target app.

When I use SetStorageItems (see commented code), none of the items are shared. The default "What's on your mind" text appears on the share panel.

Any feedback is appreciated, thank you!

Sharing of URI streamed files is unfortunately not supported. Here's how I would go about doing this:

1. When the user clicks the share button, start downloading the file and show some sort of progress if it's a big file. You could also pre-download the file of course. Set up a StorageFile instance containing the file.
2. Call DataTransferManager.ShowShareUI
3. In your DataRequested handler, use SetStorageItems to share the StorageFile instance.
