Any thoughts Bipin Joshi discusses the basics of using Data annotation attributes in an ASP. NET MVC application to perform validations at the model level. In this article you will learn about ASP. NET Interview questions and answers. Step 1 Creating a New ASP. NET MVC Project. ASP. Mob Rule No Cd Crack on this page. NET MVC is a Microsoft supported framework for creating ASP. NET applications using a. Model View Controller pattern. In a nutshell, ASP. NET MVC allows developers much finer control over. SEO friendly URLs. The ASP. NET MVC framework was first introduced in the days of Visual Studio 2. ASP. NET 3. 5 SP1, and can still be. The ASP. NET MVC framework was shipped as part of the. NET framework starting with. NET 4, so if you are using Visual Studio 2. ASP. NET 4. there is nothing extra you need to install or configure in order to start developing ASP. NET MVC applications. Lets get started creating a new ASP. NET MVC application. Begin by launching Visual Studio and going to File New Project. Select the. ASP. NET MVC 2 Empty Web Application template name the Solution Grid. Demos. MVC and the Name of the project Web and click OK see the screen shot below. A new ASP. NET MVC project even a so called empty one consists of a number of default files and folders. Content this folder is designed to contain static site content, such as CSS files, images, and so on. Controllers this folder will contain the applications Controllers. In MVC, the Controller is responsible for handling the incoming. Model and View to generate the response. Controllers are implemented as classes and their methods which are referred to as. URL of the appropriate format is requested. Models this folder is used to hold the Models. Models are implemented as classes and contain the data and business. Scripts this folder contains the j. Query and Microsoft ASP. NET Ajax Library Java. Script files. Views this folder holds the Views, which are responsible for generating the content returned to the requestor. Views typically contain. HTML, Java. Script, and server side code. Unlike the Web. Forms model, where the server side code is located in a separate code behind class, with views the. Moreover, the server side code in Views is typically very simple, serving only to loop. Model so as to generate the pages markup. A Views server side code should not contain business logic. Global. asax behind the scenes, ASP. NET MVC uses ASP. NET Routing. extensively. By default, ASP. NET MVC applications contain a single routing rule that defines the following URL pattern. When a URL arrives. CategoriesViewBeverages. ASP. NET MVC executes the controller. Controller classs action method, passing in. In the case of. www. CategoriesViewBeverages. ASP. NET MVC would execute the Category. Controller classs View method, passing in. Beverages as the input parameter to the method. At this point we have the skeleton of our ASP. NET MVC application Step 2 Adding the Northwind Database and Creating the Linq To SQL Classes. Before we start adding Controllers and Views, lets first get our Models and database squared away. The demos in this article series display data from the Northwind. Create an AppData folder in your project and add the two database files. Now we need some way to access the data from the database. There are a variety of data access options available for this article series I decided to go with. Linq to SQL, which is an object relational mapping ORM tool from Microsoft. I chose Linq to SQL. ORM to get started with. I didnt want to get bogged down on the data access side since this article series. In a nutshell, using Linq to SQL entails adding a special file to our. Linq to SQL then creates classes that model these tables as well as a Data. Context class. that is used to update and retrieve data to and from the database. Linq to SQL allows us to programmatically work with our databases data using terse, readable code. Intelli. Sense, and so on. With Linq to SQL or any ORM, for that matter theres no need waste. ADO. NET code or craft SQL statements. If you are not familiar with Linq to SQL, or are just getting started, I highly recommend Scott Guthries. Linq to SQL. Because we will be using the classes created by Linq to SQL as the Models in our application, add the Linq to SQL file to the Models folder. Specifically. right click on the Models folder and choose to add a new file. From the dialog box, select the LINQ to SQL Classes template and name the file. Northwind. dbml. This will create the new file and open it, showing you the Linq to SQL designer. Next, go to the Server Explorer and expand the northwnd. Drag both the Categories and Products tables onto the. Thats all there is to itAt this point we have our data access layer in place. Step 3 Adding the Content Files to the Project. If youre following along from your computer, you should have the folders and files from when you first created the ASP. NET MVC application, as well as the AppData and. Northwind database files, and the Northwind. Models folder. There are a number of additional content files used in. Master Pages and ASP. NET AJAX Cby Scott Mitchell. Download Code or Download PDFDiscusses options for using ASP. NET AJAX and master pages. Looks at using the Script. Manager. Proxy class discusses how the various JS files are loaded depending on whether the Script. Manager is used in the Master page or Content page. Introduction. Over the past several years, more and more developers have been building AJAX enabled web applications. An AJAX enabled website uses a number of related web technologies to offer a more responsive user experience. Creating AJAX enabled ASP. NET applications is amazingly easy thanks to Microsofts ASP. NET AJAX framework. ASP. NET AJAX is built into ASP. NET 3. 5 and Visual Studio 2. ASP. NET 2. 0 applications. When building AJAX enabled web pages with the ASP. NET AJAX framework, you must add precisely one Script. Manager control to each and every page that uses the framework. As its name implies, the Script. Manager manages the client side script used in AJAX enabled web pages. At a minimum, the Script. Manager emits HTML that instructs the browser to download the Java. Script files that makeup the ASP. NET AJAX Client Library. It can also be used to register custom Java. Script files, script enabled web services, and custom application service functionality. If your site uses master pages as it should, you do not necessarily need to add a Script. Manager control to every single content page rather, you can add a Script. Manager control to the master page. This tutorial shows how to add the Script. Manager control to the master page. It also looks at how to use the Script. Manager. Proxy control to register custom scripts and script services in a specific content page. Note. This tutorial does not explore designing or building AJAX enabled web applications with the ASP. NET AJAX framework. For more information on using AJAX consult the ASP. NET AJAX videos and tutorials, as well as those resources listed in the Further Reading section at the end of this tutorial. Examining the Markup Emitted by the Script. Manager Control. The Script. Manager control emits markup that instructs the browser to download the Java. Script files that makeup the ASP. NET AJAX Client Library. It also adds a bit of inline Java. Script to the page that initializes this library. The following markup shows the content that is added to the rendered output of a page that includes a Script. Manager control lt script srcASPNETMaster. PagesTutorial0. CSWeb. Resource. T8. EVk.

The lt script srcurl lt script tags instruct the browser to download and execute the Java. Script file at url. The Script. Manager emits three such tags one references the file Web. Resource. axd, while the other two reference the file Script. Resource. axd. These files do not actually exist as files in your website. Instead, when a request for either one of these files arrives at the web server, the ASP. NET engine examines the querystring and returns the appropriate Java. Script content. The script provided by these three external Java. Script files constitute the ASP. NET AJAX frameworks Client Library. The other lt script tags emitted by the Script. Manager include inline script that initializes this library. The external script references and inline script emitted by the Script. Manager are essential for a page that uses the ASP. NET AJAX framework, but is not needed for pages that do not use the framework. Therefore, you might reason that it is ideal to only add a Script. Manager to those pages that use the ASP. NET AJAX framework. And this is sufficient, but if you have many pages that use the framework youll end up adding the Script. Manager control to all pages a repetitive task, to say the least. Alternatively, you can add a Script. Manager to the master page, which then injects this necessary script into all content pages. With this approach, you do not need to remember to add a Script. Manager to a new page that uses the ASP. NET AJAX framework because it is already included by the master page. Step 1 walks through adding a Script. Manager to the master page. Note. If you plan on including AJAX functionality within the user interface of your master page, then you have no choice in the matter you must include the Script. Manager in the master page. One downside of adding the Script. Manager to the master page is that the above script is emitted in every page, regardless of whether its needed. This clearly leads to wasted bandwidth for those pages that have the Script. Manager included via the master page yet dont use any features of the ASP. NET AJAX framework. But just how much bandwidth is wasted The actual content emitted by the Script. Manager shown above totals a little over 1. KB. The three external script files referenced by the lt script element, however, comprise roughly 4. KB of data uncompressed in a website that uses gzip compression, this total bandwidth can be reduced near 1. KB. However, these script files are cached by the browser for one year, meaning that they only need to be downloaded once and then can be reused in other pages on the site. In the best case, then, when the script files are cached, the total cost is 1. KB, which is negligible. In the worst case, however which is when the script files have not yet been downloaded and the web server is not using any form of compression the bandwidth hit is around 4. KB, which can add anywhere from a second or two over a broadband connection to up to a minute for users over dial up modems. The good news is that because the external script files are cached by the browser, this worst case scenario occurs infrequently. Note. If you still feel uncomfortable placing the Script. Manager control in the master page, consider the Web Form the lt form runatserver markup in the master page. How To Decrypt Apco 25 Encryption Software there. Every ASP. NET page that uses the postback model must include precisely one Web Form. Adding a Web Form adds additional content a number of hidden form fields, the lt form tag itself, and, if necessary, a Java. Script function for initiating a postback from script. This markup is unnecessary for pages that dont postback. This extraneous markup could be eliminated by removing the Web Form from the master page and manually adding it to each content page that needs one. However, the benefits of having the Web Form in the master page outweigh the disadvantages from having it added unnecessarily to certain content pages. Step 1 Adding a Script. Manager Control to the Master Page. Every web page that uses the ASP. NET AJAX framework must contain precisely one Script. Manager control. Because of this requirement, it usually makes sense to place a single Script.
