We have already created the Index view in the previous section. In this section, we will create the Edit view using a default scaffolding template as shown below. The user can update existing student data using the Edit view. The following figure describes the complete set of editing steps. Editing Steps in MVC. The above figure illustrates the following steps. The user clicks on the Edit link in Index view which will send Http. GET request http: //localhost/student/edit/. This request will be handled by Http. GET Edit action method.(by default action method handles Http. GET request if no attribute specified) 2. Http. Get Edit action method will fetch student data from the database, based on the supplied Id parameter and render the Edit view with that particular Student data. The user can edit the data and click on the Save button in the Edit view. The Save button will send a Http. POST request http: //localhost/Student/Edit with the Form data collection. The Http. POST Edit action method in Student. Controller will finally update the data into the database and render an Index page with the refreshed data using the Redirect. To. Action method as a fourth step. So this will be the complete process in order to edit the data using Edit view in ASP. NET MVC. So let's start to implement above steps. We will be using following Student model class for our Edit view. Student Model - C#: publicclass. Student. . For example, an Edit link with student John will append a Student. Id=1 query string to the request url because John's Student. Id is 1. Likewise all the Edit link will include a respective Student. Id in the query string. Step 2: Now, create a Http. GET Edit action method in Student. Controller. The Index view shown above will send the Student. Id parameter to the Http. Get Edit action method on the click of the Edit link. Second, it should render Edit view with the student information so that the user can update it. So, the Edit() action method should have a Student. Id parameter. MVC framework will automatically bind a query string to the parameters of an action method if the name is matches. Please make sure that parameter name matches with the query string. Example: Http. Get Edit() Action method - C#using MVC. In a real life application, you can get the student from the database instead of sample collection. By default, MVC framework will look for Edit. Edit. vbhtml or Edit. Edipt. ascx file in View - > Student or Shared folder. It will open Add View dialogue. Html. Begin. Form sends a Http. Post request by default. Edit view will be display student information whose Edit link clicked, as shown below. Save method should send a Http. POST request because the POST request sends form data as a part of the request, not in the querystring. So write a POST method as fourth step. The Edit() view will automatically binds form's data collection to the student model parameter. Please visit Model Binding section for more information. Here, you can update the information to the database and redirect it to Index action. However, you can also create an Edit view without using an Edit scaffolding template.
