New Features In ASP.NET 4.5 Webforms
The new version 4.5 of ASP.NET Web Forms has come up with a string of latest value-added features that are specifically designed as well as developed for superior user experience, that come in handy at the time of working with huge databases.
In all the earlier versions of ASP.NET, the users had to use various expressions like Bind() and Eval() while using data-binding for deriving the object member value. However, in case of the latest version, the users will be able to declare the type or class of the control-bound data with the use of the new ItemType property. Once this property is set, the user will be able to use a strong variable for receiving the benefits that Visual Studio features. Some of the benefits include effective member navigation, IntelliSense, compilation-time checking option and so on.
The latest data-bound controlling features also help the users to specify customized methods that may be used to select, update, modify, delete, or insert data, and to simplify the interactions between application logics and page controls. Besides, the latest version also comes up with a latest model binding feature that helps users to map the data directly from the page into the method parameters.
Validation of user input has become much easier in the latest version which helps users to annotate the customized model classes with various attributes of validation from the System.ComponentModel.DataAnnotations namespace.
The new 4.5 version of the web form also integrates jQuery with the client end validation and that provides a much cleaner as well as more composite client-end codes along with the standard features of JavaScript.
Besides, with the introduction of the new version the area that is designated for requesting validation has seen certain improvements. These new features make it much easier for the users to deactivate the request validations selectively, for certain definite parts of the application. Also, going through the request data that have been invalidated, becomes much easier in the newer version.
