How to attach single view with multiple action
Attach single view with multiple actions.
In this article we will learn how to attach single view with
multiple actions. It’s common situation
in project development where we don’t want to create view for each and every
action of certain controller. In this situation, we have to use concept of
shared view. The solution is very simple; just we have to keep the view in
shared folder. Like below.
Now, The question is why need to keep in shared folder?. The
reason is when we run any controller, by default it check its own directory or
shared directory. Every controller will
look in shared directory, if it not available in it’s own directory. Let’s have
a look on below code.
Here we will create very simple controller class
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace MVC3.Controllers
{
public class HomeController : Controller
{
//
// GET: /Home/
public ActionResult Action1()
{
ViewBag.Controller = "Action1";
return View("_Common");
}
public ActionResult Action2()
{
ViewBag.Controller = "Action2";
return View("_Common");
}
}
}
Both Action1() and Action2() is calling _Common view and as
the view is placed in shared folder, both can able to access. Before calling to
view we are assigning action name in ViewBag. From view we can detect which
action has invoked it.
Here is code for view
<%@ Page
Language="C#"
Inherits="System.Web.Mvc.ViewPage<MVC3.Models.customer>"
%>
<!DOCTYPE html>
<html>
<head runat="server">
<title>_Common</title>
</head>
<body>
<div>
<% var ActionName = ViewBag.ActionName; %>
<% if (ActionName == "Action1")
{%>
This view is called from Action 1
<%}
else
{%>
This view is Called from Action 2
<%} %>
</div>
</body>
</html>
Here is output.
Now, the question may arise “Is it possible to call one view
from different controller”? Yes, we can call. In below example, we will see how
to do that.
Call one view from different controller
This is our first controller Home1
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace MVC3.Controllers
{
public class Home1Controller : Controller
{
public ActionResult Action()
{
ViewBag.Controller = "Home1";
return View("_Common");
}
}
}
Here is Home2 controller
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace MVC3.Controllers
{
public class Home2Controller : Controller
{
public ActionResult Action()
{
ViewBag.Controller = "Home2";
return View("_Common");
}
}
}
It’s clear that both Action() (they are in different controller)
are calling same view. And here is output.
Conclusion
Here we have discuss how to attach single view with multiple actions. Hope you have understood the concept.
