    Secure, Browser-Agnostic ASP.NET PDF Viewer with DRM Features

    This sample project is created by the GroupDocs showcase team to demonstrate key benefits of an ASP.NET PDF viewer built using the commercial library – GroupDocs.Viewer for .NET. The viewer allows you to display PDF documents across all standard web-browsers (IE8+, Chrome, Mozilla Firefox, Safari 5+, Opera, etc.) without having to install any software or plugins on end-user machines.
