What is MVC (Model View Controller)?

Model–view–controller (MVC) is a software architectural pattern for implementing user interfaces. It divides a given software application into three interconnected parts, so as to separate internal representation of information from the way that information is presented to or accepted from the user.

MVC is a framework for building web applications using an MVC (Model View Controller) design:

  • The Model represents the application core (for instance a list of database records).
  • The View displays the data (the database records).
  • The Controller handles the input (to the database records).
  • The MVC model also provides full control over HTML, CSS, and JavaScript.

    The MVC model defines web applications with 3 logic layers,

  • The business layer (Model logic)
  • The display layer (View logic)
  • The input control (Controller logic)
  • The Model is the part of the application that handles the logic for the application data.

    Often model objects retrieve data (and store data) from a database.

    The View is the part of the application that handles the display of the data.

    Most often the views are created from the model data.

    The Controller is the part of the application that handles user interaction.

    Typically controllers read data from a view, control user input, and send input data to the model.

    The MVC separation helps you manage complex applications because you can focus on one aspect a time. For example, you can focus on the view without depending on the business logic. It also makes it easier to test an application.

    The MVC separation also simplifies group development. Different developers can work on the view, the controller logic, and the business logic in parallel.

    1 Explain what is the difference between View and Partial View?


  • It contains the layout page.
  • Before any view is rendered, viewstart page is rendered.
  • A view might have markup tags like body, HTML, head, title, meta etc.
  • The view is not lightweight as compare to Partial View.
  • Partial View

  • It does not contain the layout page.
  • Partial view does not verify for a viewstart.cshtml.We cannot put common code for a partial view within the viewStart.cshtml.page.
  • Partial view is designed specially to render within the view and just because of that it does not consist any mark up.
  • We can pass a regular view to the RenderPartial method.

    2 What is Validation Summary in MVC?


    The ValidationSummary helper method generates an unordered list (ul element) of validation messages that are in the ModelStateDictionary object.

    The ValidationSummary can be used to display all the error messages for all the fields. It can also be used to display custom error messages. The following figure shows how ValidationSummary displays the error messages.

    ValidationSummary() Signature

    MvcHtmlStringValidateMessage(bool excludePropertyErrors, string message, object htmlAttributes)

    Display field level error messages using ValidationSummary

    By default, ValidationSummary filters out field level error messages. If you want to display field level error messages as a summary then specify excludePropertyErrors = false.

    Example – ValidationSummary to display field errors

    @Html.ValidationSummary(false, “”, new { @class = “text-danger” })

    So now, the following Edit view will display error messages as a summary at the top. Please make sure that you dont have a ValidationMessageFor method for each of the fields.
