A trend becoming increasingly popular is to have a single web page perform all of these operations. So, in this example instead of developing four separate web pages you develop just one web page.
NET MVC 4 has decided to offer some basic infrastructure to the developers to put this concept into practice. You can then customize the application to add more functionality. A Single Page Application consists of several pieces that fit together to provide the overall functionality of the application.
A typical SPA consists of the following pieces:. Net MVC 4 Project. The default project created using the SPA project template contains data models, views and client script files for performing CRUD operations of a sample "To Do" application. The following figure shows these libraries added in the Solution Explorer. Knockout and Upshot Libraries.
A task is represented by a data model class - TodoItem. The TodoItem class resides in the Models folder and looks single page application in asp.net mvc4 this:. As you can see the TodoItem is a simple class with three properties, viz. This is done for you when you add a new controller to the project specifying learn more here SPA controller template.
In the Add Controller dialog specify details as shown below:. Specify the just click for source name as TodoController. In the Model class drop-down select TodoItem class. In the Click here context class drop-down click single page application in asp.net mvc4 data context" and specify a name for click the following article DbContext class.
Knockout synchronizes the data between views and ViewModel. The communication between the ViewModel and the server side data happens through Upshot. Three partial views are also created viz. Depending on the operation selected by the user the appropriate partial view is rendered. The following markup shows a fragment from the Index. Metadata method provides the metadata of the types to the Upshot. If you run the application and navigate to http: You can click on the "Create TodoItem" button to add a few records.
You can then modify or delete them. The following figure shows the view in edit mode. At this stage the sample "To do" application is able to store and retrieve the data but you might be wondering where the actual data is. Http://square-games.de/bekanntschaften-sauerland.php SPA uses Code First approach to database operations, the database is automatically created for you when you run the application for the first time.
The subsequent runs use the previously created database. Have a look at the following figure that shows a sample database generated under local installation of SQL Express. Sample database generated under local installation of SQL Express. As you can see, by default the database name is the same as the fully qualified name of the DbContext class.
Inside there is a TodoItems table that stores the application data. Single Page Applications heavily use client side scripting to provide rich functionality to the end user. Instead of creating multiple web pages to perform a set of operations SPA uses a single web page to perform the same tasks.

The page does not re-load at any point in single page application in asp.net mvc4 navigation process. For read article communication we use Hachenburg partnersuche calls and update the sections appropriately. Client-side navigation is done using Hash based techniques. Getting Started Let us create the demo application and learn step-by-step.
Here we are trying to create a single page where the user can browse the list of products, edit the existing product and delete the product. We will create a single page to perform all these operations.
Now we have the solution ready. Now we have our controller ready with an Index action. Single page application in asp.net mvc4 we are ready to run our application. We should be able to see single page application in asp.net mvc4 Index page. We will name click "ProductViewModel". Create a new folder "Application" under the "Script" folder.
We will name it "currentProduct", this property will hold the current product information. Please click for source now create a new Product object, initialize it with some dummy values and assign it to the "currentProduct" property. Now we need to add reference single page application in asp.net mvc4 Knockout. Add the new script bundle as single page application in asp.net mvc4. Now go to "Index.
Here we are adding the reference of "Product. Now we will see how to bind the ViewModel properties to UI controls. Just to explain the concept I will use one TextBox and one label and bind the productName to both controls.
Add the following code in the single page application in asp.net mvc4. You can see that we have used the data-bind attribute for binding.
Now run the application and you should see the following output. Because of the use of declarative binding we can see the product name shown on the UI. Now since we have bound the same property http://square-games.de/single-potsdam.php both text and label, if we change the text box value then it should automatically be reflected in the label.
Now try to change the http://square-games.de/single-frauen-garbsen.php box value and tab off. You should see the following output. This proves that we have implemented MVVM correctly. Now we will return to our actual UI that we had planned to show, the list of products and the user can edit and delete the product. Remove the following code from "Index. Single page application in asp.net mvc4 we will update the ProductViewModel as per the requirements.
We need a list свои partnersuche sonthofen провожу products. So add the products property into ProductViewModel to hold the list of Product objects. Now since this a Single Page Application we will create two sections on the same page, one section to show the list of products and another section to display the product information in edit mode. I have made the Product List section visible by default.
Please use the following single page application in asp.net mvc4 shot and update the Index. Now we will render two action links for each product to edit and delete that product.
Make the highlighted changes in Index. Here we are using click binding and calling the "editProduct" and "removeProduct" functions of ProductViewModel. The Product Code field should be disabled. Here we are binding with the currentProduct property of ViewModel. By default I initialized the currentProduct with blank values. Now partnersuche lange the user clicks on the Edit link we need to redirect to the Edit Product section.
Here you can see that in the editProduct function we are just setting the Hash. Because of the Knockout binding mechanism we get the product object that is bound to that row. In the Sammy function the code block will be executed automatically for a specific route. In our case we are just hiding the product list div and showing the edit product div.
Now when you run the application, you should be able to see the following output. Now when you click on "Edit", you will see the Edit Product section visible, that we are doing in the Sammy function.
Please observe the URL in the address bar in the following screen shot. In the getProduct function we are just traversing the observableArray and matching the selected product based on the product code. Also setting the currentProduct property. Update the Sammy function as below. Now run the application, you should be able to see the output as below.
Now try to change the product code directly in the address bar and see the behavior. When we change go here URL in the address bar, Sammy captures the URL and it matches with the route we configured and the code block associated to that route is executed.
