Overview

 Using Dynamic Data, ASP.NET developers can create powerful, datadriven sites with amazing speed and efficiency, eliminating massive amounts of manual coding. ASP.NET Dynamic Data Unleashed is the first complete, practical guide to Dynamic Data for every experienced ASP.NET developer.   The author thoroughly demystifies Dynamic Data, helping developers understand exactly what they can do with the framework and make it more accessible than ever before. He provides tested code to solve a wide variety of problems, explains how and why that code works, and identifies key tradeoffs and alternatives.   Packed with breakthrough techniques for improving developer productivity, this book combines a hands-on tutorial, “drill-down” explanations of advanced techniques, and real-world development scenarios.   Detailed information on how to…  Use Dynamic Data components to overcome common real-world user interface development challenges   Understand how ASP.NET Dynamic Data builds on strengths of WebForms, Entity Framework, and LINQ   Develop simple custom templates to dramatically reduce code duplication   Generalize templates to leverage metadata and generate user interfaces dynamically   Create web pages for data entry, data filtering, and diverse views of data   Use Data Annotations to implement powerful validation logic   Write simple, yet effective automated tests to systematically verify the business logic   Create complex interaction rules that aren’t limited by single entity objects or types   Optimize I/O-bound business logic by implementing it with T-SQL constraints, stored procedures, and triggers   Implement role-based security with dynamic UI trimming   Generate entire data-driven web applications, complete with CRUD pages, complex business rules, integrated navigation, and security   Extend Dynamic Data to support advanced scenarios   Decide when Dynamic Data should be used instead of or together with ASP.NET MVC
