How to Specify Different Layouts in the ASP.NET MVC 3 Razor ViewStart File

🎉 Welcome to another blog post on our tech blog! 🎉 In this post, we'll tackle a common issue that many developers face when working with ASP.NET MVC 3 Razor: specifying different layouts for different sections of your website. 🖥️

The Problem

Let's say you have two distinct sections on your website: the Public section and the Member side. Each section has its own logic, controllers, and corresponding layouts:

• PublicController 🌍

• StaffController 👥

Layouts:

• _PublicLayout.cshtml 📃

• _StaffLayout.cshtml 📃

The challenge now is to instruct ASP.NET MVC 3 Razor to use the correct layout for each section without manually specifying it in every single view.

The Solution – ViewStart File

The ASP.NET MVC 3 Razor framework provides a handy solution for these kinds of scenarios – the ViewStart file. The ViewStart file allows you to define a set of instructions that apply to all views within a specific folder or hierarchy.

To create a ViewStart file, follow these steps:

1. Open your project in Visual Studio.

2. Navigate to the desired folder where you want to apply a specific layout. In this case, we'll navigate to the Views/Public folder and the Views/Staff folder.

3. Create a new file and name it _ViewStart.cshtml.

4. Open the _ViewStart.cshtml file.

Applying the Correct Layout

Inside the _ViewStart.cshtml file for the Public views, add the following code:

@{
    Layout = "~/Views/Shared/_PublicLayout.cshtml";
}

And for the Staff views, add the following code:

@{
    Layout = "~/Views/Shared/_StaffLayout.cshtml";
}

By specifying the layout path in the ViewStart file, you're telling ASP.NET MVC 3 Razor to use the designated layout file for all views within that folder or hierarchy.

Verifying the Results

To ensure that the layouts are correctly applied, let's do a quick test.

1. Open any view within the Public folder, for example, Index.cshtml.

2. Add some content or a simple HTML tag to the view, such as <h1>Welcome to the Public Section!</h1>.

3. Repeat the same steps for a view within the Staff folder, for example, Index.cshtml again with the content <h1>Welcome to the Member Section!</h1>.

4. Run your application and navigate to both sections (Public and Staff) to see if the correct layouts are applied and the respective content is displayed.

Voila! Your ASP.NET MVC 3 Razor application is now using different layouts for different sections, thanks to the convenient ViewStart file.
