In MVC we cannot pass more than one models from a controller to the single view. To overcome this we can use ExpandoObject class. The .NET 4.0 framework actually includes an ExpandoObject class which provides a dynamic object that allows us to add properties and methods on the fly. From msdn, Represents an object whose members can be dynamically added and removed at run time. In some time we need to display more than one type of model data in to the single view. For example i am having two models namely CustomerDetails and EmployeeDetails and if i need to display both information in single view then we can use the ExpandoObject. Creating simple model namelu CustomerDetail.cs and EmployeeDetail.cs as shown below. CustomerDetail.cs
EmployeeDetail.cs

How to use multiple model in view
If we have two model classes like Customer details and Employee detail. ASP.NET MVC allows you to pass only One model to a view. The view can be bound with one and only one model. From the above statement, we understood that either pass customer or employee details to the view. Then What if a view requires to display both models?. Let us we discuss the situation as follows:
