Description:

Discover how to use ADO.NET and ASP.NET essentials to take your Web programming skills to the next level.

Most Web applications follow a simple “3F” pattern: fetch, format, and forward to the browser. With this in-depth guide, you’ll take your ASP.NET and ADO.NET skills to the next level and learn key techniques to develop more complex Web applications. Discover how to build applications for ad-hoc and effective Web reporting, applications that work disconnected from the data source and use XML to communicate with non-.NET systems, and general-purpose applications that take advantage of the data abstraction of ADO.NET. Along the way, you’ll learn how to take advantage of code reusability, user controls, code-behind, custom Web controls, and other time-saving techniques employed by ASP.NET experts. Topics covered include:

• Data-bound .NET controls
• Templated and editable data grids
• Code reusability in .NET
• Advanced reporting
• Disconnected applications
• Interoperable applications
• XML Web services
• .NET Managed Providers

CD-ROM FEATURES:
• A fully searchable electronic copy of the book
• Sample code written in Microsoft® Visual C#™ .NET and Visual Basic® .NET
