Sharing an image in Windows Phone 8.1 - windows

Question

I'd like to share an image in my app. However, the image is not located in a folder but it is "taken dynamically". Basically i have an Image object
Image i = new Image() { Source = await CreateBitmapFromElement(stackpanel1) };
where CreateBitmapFromElement is defined as follows
private async Task<RenderTargetBitmap> CreateBitmapFromElement(FrameworkElement uielement)
{
try
{
var renderTargetBitmap = new RenderTargetBitmap();
await renderTargetBitmap.RenderAsync(uielement);
return renderTargetBitmap;
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine(ex);
}
return null;
}
The Windows Phone Share Contract allows to share images located in the Picture Library (for example), but what should i use in this case?

Answer 1

protected override void OnNavigatedTo(NavigationEventArgs e)
{
DataTransferManager.GetForCurrentView().DataRequested += OnShareDataRequested;
base.OnNavigatedTo(e);
}
protected override void OnNavigatedFrom(NavigationEventArgs e)
{
DataTransferManager.GetForCurrentView().DataRequested -= OnShareDataRequested;
base.OnNavigatedFrom(e);
}
private void OnShareDataRequested(DataTransferManager sender, DataRequestedEventArgs _dataRequestedEventArgs)
{
DataRequest request = _dataRequestedEventArgs.Request;
request.Data.Properties.Title = "KeyTreat Sticker";
request.Data.Properties.Description = "KeyTreat Sticker: " + StickerName;
// Because we are making async calls in the DataRequested event handler,
// we need to get the deferral first.
DataRequestDeferral deferral = request.GetDeferral();
// Make sure we always call Complete on the deferral.
try
{
request.Data.SetStorageItems(storageItemsObject);
request.Data.Properties.Thumbnail = RandomAccessStreamReference.CreateFromFile(StorageFileObject);
request.Data.SetBitmap(RandomAccessStreamReference.CreateFromFile(StorageFileObject));
}
finally
{
deferral.Complete();
}
}
