What is ViewBag.Title in Razor?

Question

What is ViewBag.Title in ASP.NET MVC 4?

I have that View file:

@model IEnumerable<MvcMusicStore.Models.Genre>  @{     ViewBag.Title = "Store"; }  <h2>Index</h2> 

and I do not know what changing ViewBag.Title may accomplish.

From the ASP.NET site:

ViewBag is a dynamic object, which means you can put whatever you want in to it; the ViewBag object has no defined properties until you put something inside it.

The ViewBag.Title property is simply a string object. In this case it's being used in the view to actually define the Title property. If you were to look in your _Layout.cshtml file you would likely see something like:

<title>@ViewBag.Title</title> 

Remember when the property was defined in the view? When the page is finally rendered, that property ends up in the HTML markup looking like:

<title>Store</title> 

Which sets the browser title.
