ASP.NET MVC : What is Partial View

Partial view is just like User Control in ASP.NET applications. But there is big difference between Partial view and user Control. Because For calling User control you have to register that control on the Content page or master page. In Case of Partial view we don’t have to register or don’t need any configuration to access Partial view. 

Usually we use Partial View name start with unserscore "_" as "_PartialViewName"
Just render partial view on view using

@Html.RenderPartial("_PartialViewName")

If Partial View has model then render partial view with model

@Html.RenderPartial("_PartialViewName",model)

This can be done on View only.
But if you want to Render PartialView on calling Action then

public class HomeController : Controller
{
     public PartialViewResult GetName()
     {
         // Do code for logical operation

         return PartialView("_PartialViewName");
     }
            
}

This can be done on ajax call using Jquery

function Insert()  
{    
   $.ajax({  
       url: @Url.ActionLink("GetName","Home"),  
       type="GET",        
       success:function(data)  
       {  
           // Display Partial View
          $("#DivName").html(data);
       }  
    });    
}  

There are different ways to render Partial View

Html.RenderPartial

This method render Partial View directly

@Html.RenderPartial("_PartialViewName")

Html.RenderAction

This method excute the Action and return output as partial view

@  
{ 
Html.RenderAction("ActionName","Controllername"); 
}

Html.Partial

This Method also render Partial View directly But it return as Html-encoded string output . We can store it on variable and use when it required

@Html.Partial("_PartialViewName")

Html.Action

This method also render the partial view as Html string and we can also store it on variable and use when it required

 @
{ 
Html.Action("ActionName","Controllername"); 
}
