How to use ViewBag?

ViewBag is dynamic property that takes advantage of new dynamic features in C# 4.0. It’s also used to pass data from a controller to a view. In short, The ViewBag property is simply a wrapper around the ViewData that exposes the ViewData dictionary as a dynamic object. Now create an action method “StudentSummary” in the “DisplayDataController” controller that stores a Student class object in ViewBag.

1. public ActionResult StudentSummary()  
2. {  
3.     var student = new Student()  
4.     {  
5.         Name = “Sandeep Singh Shekhawat”,  
6.             Age = 24,  
7.             City = “Jaipur”  
8.     };  
9.     ViewBag.Student = student;  
10.     return View();  
11. }  

Thereafter create a view StudentSummary (“StudentSummary.cshtml”) that shows student object data. ViewBag does not require typecasting for complex data type so you can directly access the data from ViewBag.

1. @ {  
2.     ViewBag.Title = “Student Summary”;  
3.     var student = ViewBag.Student;  
4. }   
5. < table >  
6.     < tr >  
7.     < th > Name < /th> < th > Age < /th> < th > City < /th> < /tr> < tr >  
8.     < td > @student.Name < /td> < td > @student.Age < /td> < td > @student.City < /td> < /tr>   
9. < /table>  

Here we used one more thing, “ViewBag.Title”, that shows the title of the page.
