If you want to be able to show the uploaded file you will have to store it in some other folder than the App_Data. Files are not directly accessible by clients from this folder. You could for example use the Content folder instead. Once you get the file appear in this folder on the server you could reference it from the view using the <img> tag: <img src="@Url.Content("~/content/someimage.jpg")" /> where you could pass the name of the file to the view from the upload action.
