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).
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.
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.
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).This expression is very straightforward in the current version of ASP.NET: call the Bind method and pass the name of the property you want to bind to (for my Last Name property I would enter Bind(“Last Name”), for instance).In this example, I'm assuming that I'm displaying a set of Customer objects of some kind in a List(of Customer).I first check to see if the List is in the Session object and, if it isn't, build it.
