NET that allow you to easily create websites for working with the CRUD operations of an entire data model that exists as either a Data Context (such as LINQ to SQL) or an Object Context (such as LINQ to Entities). NET provides several server controls that build on top of the features of Microsoft ADO. These controls simplify the development of data-driven websites.I’ve seen many simple business applications that suffered from over-engineering. NET can now generate a data layer for you by using LINQ to Entities.Many of these smaller applications can take advantage of the simple data-binding techniques built into the Visual Studio ASP. These applications can be created quickly, typically do not require much testing, and allow developers to focus on solving business problems rather than building frameworks and reusable objects that might never realize the goal of reusability. Applications that can benefit from this approach often have a common profile: they typically have compressed schedules, are meant to be websites from beginning to end, and might fill a somewhat temporary need.When optimizing for these considerations, you might find that building data-bound applications by using the server controls in ASP. They make it easier to build webpages that access, display, manipulate, and save data. You use these controls to configure access to data that you intend to use on a webpage.Using these controls can provide development efficiency when you are building business applications that rely heavily on data. A data source can be a relational database, data stored inside of in-memory objects (such as a Data Set or an Entity Data Model), XML-based data, or data you retrieve via Microsoft Language-Integrated Query (LINQ).

The second lesson in this chapter demonstrates how you can bind to data to allow users to interact with it.

The lesson covers using web server controls such as Grid View, Repeater, Details View, and many more.

The last lesson presents the new Dynamic Data features of ASP.

NET that allow you to easily create websites for working with the create, read, update, and delete (CRUD) operations of an entire data model that exists as either a Data Context (such as LINQ to SQL) or an Object Context (such as LINQ to Entities).

To complete the lessons in this chapter, you should be familiar with developing applications with Microsoft Visual Studio 2010 by using Microsoft Visual Basic or Microsoft Visual C#.

In addition, you should be comfortable with all of the following: REAL WORLD: Mike Snell Not all applications require developers to write custom, abstracted data layers and reusable frameworks.
