Introduction The Layout View is an essential feature in ASP .NET MVC that allows you to define a consistent layout for your web application. It provides a way to define the common structure and visual elements (such as headers, footers, menus, etc.) that are shared across multiple pages in your application.
Defining a Layout View To define a Layout View in ASP .NET MVC, follow these steps:
Create a new file with the
.cshtml
extension, such as_Layout.cshtml
. The underscore at the beginning of the file name is a convention to indicate that it is a partial view.Inside the Layout View file, define the common HTML structure for your application. This typically includes the
<html>
,<head>
, and<body>
elements.Within the
<body>
element, define the common sections of your layout, such as the header, navigation menu, main content area, and footer. You can use HTML, CSS, and JavaScript to customize the appearance and behavior of these sections.
Example of a Layout View
Here's an example of a basic Layout View file (_Layout.cshtml
):
html<!DOCTYPE html>
<html>
<head>
<title>@ViewBag.Title</title>
<!-- Include CSS and JavaScript files here -->
</head>
<body>
<header>
<!-- Header content goes here -->
</header>
<nav>
<!-- Navigation menu goes here -->
</nav>
<main>
@RenderBody()
</main>
<footer>
<!-- Footer content goes here -->
</footer>
</body>
</html>
In this example, @ViewBag.Title
is used to dynamically set the page title. The @RenderBody()
method is used to render the content of each individual view within the main content area of the layout.
Using the Layout View To use the Layout View in your individual views, follow these steps:
Set the
Layout
property in your view file to the path of the Layout View file. For example, if your Layout View file is_Layout.cshtml
and it resides in theViews/Shared
folder, you can set the Layout property as follows:csharp@{ Layout = "~/Views/Shared/_Layout.cshtml"; }
Within your individual view file, define the content specific to that view. This content will be rendered within the
@RenderBody()
call in the Layout View.
Conclusion The Layout View in ASP .NET MVC allows you to define a consistent structure and appearance for your web application. By separating the layout from the content, it promotes code reusability and maintainability. It enables you to create a professional and visually appealing user interface across multiple pages of your application.
