  • This example demonstrates how to use RadUpload for Silverlight within ASP.NET Ajax web site in order to achieve rich web mail UI. Stand-alone examples are also available:

    Requirements:

    1. A Silverlight application (XAP) which contains RadUpload for Silverlight. We provide a ready for use xap file and its Visual Studio project (should you need to customize it).
    2. The HTTP handler which saves the files uploaded by RadUpload.
