It is the model binder which acts as a bridge between the View and the MVC models. This method is responsible for binding a model to some values using ControllerContext and BindingContext. IModelBinderProvider interface - This interface contains methods that enables dynamic implementation of model binding for classes which implement the IModelBinder interface.

This is used to manage the custom binder for the type of data defaultmodelbinder mvc 4 by the end-user in views. The Model Binder can represented defaultmodelbinder mvc 4 the following diagram: We will use Visual Studio for implementing the application although you are free to use Visual Studio too. Step 1: Create a new ASP.

Click on OK, this will show the following window, select Empty template and MVC checkbox as shown in the defaultmodelbinder mvc 4 image. Step 2: Keep this database empty. In the Models folder, add a new ADO. In the wizard, select Code-First from database as shown in the following image.

Select the ApplicationDB. This will cbeebies ApplicationEntities. This class is derived from DbContext class. We will use this class for performing Database operations.

Step 3: In the models folder, add a new class file of name Employee. Since we need to generate table from this class, add the following line in ApplicationEntities class. Step 4: In this controller, add the following action methods:. The above code uses the ApplicationEntities object to communicate with the database. The Create action method is very important here. This uses an XmlSerializer class to define the type of XML data which will be received from the post request.

Using the Deserialize method, the request is read and stored in the Employee defaultmodelbinder mvc 4 which will be further used for database operations skipped here.

Put the break point on this method so that we can test it. To test the data, we will use fiddler tools here Postman can also be used. Step 5: Execute the call by clicking on the Execute button, the following debug result will be displayed in our Emp object declaration in code. The code is showing the Employee data posted.

This is the place where ModelBinder comes into picture. In our case, we need to implement an infrastructure using which XML data posted will be mapped to the Defaultmodelbinder mvc 4 object.

We can do this using a Custom Model Binder. Step 6: In the project add a new folder of name CustomModelBinders. In this folder add a class file with the following code. This method reads the content type from the incoming request.

Step 7: We will add the above custom model provider class in the application, so that application will load it in the model binder process. Open Global. The ModelBinderProviders will add the binder providers in the application which we have created in the previous step.

Step 8: Change the code of the Create Defaultmodelbinder mvc 4 method in the EmployeeController class as shown in the following code highlighted. Apply a breakpoint on the Create action method and run the application using Fiddler.

Choose the same data as shown in Step 5. Custom Model Binder provides a mechanism using which we can map the data from the request to our ASP. Download the entire source code of this article Github.
