In this article i will give small description about mvc partial view and i will give a small example how you can load partial view based on condition.
In MVC Partial view act as a container. It is used for displaying the information on conditional bases.
So for this first create mvc3 web application and add a controller . In your controller add the below code.
public ActionResult Index()
{
return View();
}
Now create the index view. Now in your view add the below code.
@{
ViewBag.Title = "Index";
}
@using (Html.BeginForm("Index", "Home"))
{
<select name="partialview">
<option value="1">Partial View 1</option>
<option value="2">Partial View 2</option>
</select>
<br /><br />
<input type="submit" value="Submit" />
if (ViewBag.Page == "1")
{
@Html.Partial("PartialView1");
}
else if (ViewBag.Page == "2")
{
@Html.Partial("PartialView2");
}
}
In above code i have created dropdown in which i have defined the partial view name.
Now we will add two partial view. For this right click on the home view folder and click on add View .
As you click on the view option below window will open.
By clinking on the "create as partial view" you will be able to crate partial view. In same way create second partial view.

using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace Partialview.Controllers
{
public class HomeController : Controller
{
//
// GET: /Home/
public ActionResult Index()
{
return View();
}
[HttpPost]
public ActionResult Index(string partialview)
{
if (partialview == "1")
{
ViewBag.Page = "1";
}
else if (partialview == "2")
{

}
return View();
}
}
}
