Using BrowserID Authentication in ASP.NET Web Sites |
|
Using a single user ID and password across multiple web sites is not a new idea. Software companies have played with this idea with varying success. Unfortunately developers often find it complicated to implement support for these systems in their ASP.NET web sites. That is where Browser ID initiative from Mozilla Labs shines. Browser ID offers a simple way of authenticating users of your web site using their single sign-on credentials. Under Browser ID scheme, users can use any verified email address as their user ID. The actual login credentials are not stored in your database but in the Browser ID system. Thus users are free to use a single user ID and password across all the web sites that support Browser ID. In this article you will learn to use ASP.NET Forms Authentication and Browser ID hand in hand. |

Using Model Binding in ASP.NET Data Controls |
|
ASP.NET Web Forms became popular due to the wide range of data bound controls such as GridView, DetailsView and ListView. The earlier versions of ASP.NET, however, were a bit rigid about how data was bound to these controls. Most of the time developers had to use one or the other data source control (SQL Data Source, Object Data Source, Entity Data Source etc.) to bind data from the underlying data store with the data bound controls. ASP.NET 4.5 provides a flexible alternative to data bind these controls - model binding. Using the new model binding features you can use methods instead of data source controls to perform CRUD operations. This article explains how the new model binding features can be used. You will also learn to use strongly typed data controls. |

Tapping the Juice UI with ASP.NET |
|
jQuery and jQuery UI are quite popular JavaScript libraries amongst ASP.NET developers. jQuery UI provides several widgets and plugins that help you develop professional looking websites quickly and easily. Though ASP.NET developers have been using jQuery UI in their websites, one downside of the jQuery UI from an ASP.NET perspective is that it is purely a client side library. ASP.NET web forms often rely on server side processing, and configuring the jQuery UI widgets can become tedious in such cases. Juice UI attempts to provide a solution in such cases. Juice UI essentially acts as a wrapper over jQuery UI widgets so that they can be accessed in your server side script just like any other server control. This article gives you a quick overview of Juice UI components and shows how they can be used in ASP.NET Web Forms applications. |

Applying AJAX to your ASP.NET Web Sites Using jQuery |
|
With more and more web applications making use of jQuery and AJAX based techniques for communicating with the server, it has become important for any ASP.NET developer to have good grasp of jQuery AJAX techniques that can be used in ASP.NET. AJAX allows you to communicate with the server without requiring full page post back. AJAX requests perform some operation in the background while a user is still working with a page. AJAX techniques not only improve the overall performance of your web application but they can also make your web pages more responsive. jQuery offers a variety of ways to make AJAX calls to the server and this article discusses many of them as applicable to ASP.NET. |

Working with Asynchronous Operations in ASP.NET MVC |
|
Whenever you call action methods in an ASP.NET MVC application, by default they are executed in synchronous fashion. In order to improve the overall performance and responsiveness of your application you may wish to execute the code asynchronously. You may execute code asynchronously from two distinct places - server-side and client-side. This article discusses both of these scenarios and shows how to create asynchronous controllers and use SessionState attribute. |

Using Areas in ASP.NET MVC Application |
|
ASP.NET MVC relies on certain folder and class naming conventions to organize models, views and controllers. A large application often consists of functionally independent modules with the result that the main application is essentially a bundle of these sub-applications. In such cases, organizing various models, views and controllers can be tedious. Luckily, ASP.NET MVC allows you to split your application into what is known as Areas. Each area mimics the folder structure and conventions as required by ASP.NET MVC. This article shows you how Areas are used in an ASP.NET MVC application. |

Confirming Delete Operations in ASP.NET MVC |
|
Seeking confirmation of some important action, such as deleting a record, is a common practice in web applications. There are two common approaches to seek confirmation from the end user. In the first approach a dialog box is displayed to the user seeking his consent to perform the delete operation and in the second approach the user is shown a separate confirmation page. In the former approach the control remains in the page where deletion is taking place whereas in the latter case control moves to a confirmation page and the actual deletion operation happens in the confirmation page. This article illustrates how both of these techniques can be implemented in ASP.NET MVC. |

Using HTML5 Drag and Drop in ASP.NET |
|
Drag and drop operations are common in desktop applications. Modern web applications also try to harness the ease and power of drag and drop operations to provide enhanced user experience. Web developers often resorted to JavaScript based libraries or custom techniques for enabling drag and drop behavior in their applications. Luckily, HTML5 comes with an inbuilt support for drag and drop. Using drag and drop features, you can drag an HTML element and drop it onto another. In the process you can also pass data from the source element to the target element. Integrating drag and drop with server side processing allows you to provide rich user experience. This article illustrates how HTML5 drag and drop features can be used in an ASP.NET website. |

Implementing AutoPostBack in ASP.NET MVC |
|
ASP.NET Web Forms allow you to automatically post a form back to the server when the selection in a DropDownList control changes. This is achieved by setting the AutoPostBack property of the DropDownList control. The AutoPostBack feature is a handy way to refresh a page when data being displayed is dependent on the selection made in the DropDownList. In ASP.NET MVC applications you need to add this feature programmatically since they often use plain HTML markup to render a DropDownList. This article explains how AutoPostBack can be implemented in ASP.NET MVC. |
