MVC's main objective is to seperate the presentation and bussiness logics, and its also not recommend much code in views.

There may be situation we need to invoke the actions from code behinds of Views. 

Here is the code to invoke Actions of controllers programmatically,

Use the below code in any server side event.. like button click, dropdownlist selected index changed, etc

Response.Redirect(Url.Action("Action Name", "Controller Name"));

here is the eg:

Response.Redirect(Url.Action("Index", "Home"));


Passing Values

When you need to pass the values to your action through code behind,

you can use RouteValueDictionary   class, under System.Web.Routing namesapce

Cosider you have a Controlle with name "Home", and action with Name "Index" as

public

{
       //your logic
}


you can call the above Action from code behind and pass value for Id as


 RouteValueDictionary rval = new RouteValueDictionary();
  rval.Add("Id", "Value for this");
  Response.Redirect(Url.Action("Index", "Home",rval));
