Question

I want to use partial on my web to show main slide but when i use partial i keep getting error. Help me please.
Here my some code:
On Controller

DataClasses1DataContext db = new DataClasses1DataContext();
    public ActionResult TestSnew()
    {
        var snew = db.Snews;
        return PartialView(snew);
    }

On View

@model Jiremsenmn.Models.Snew
Some Html code to shown

On Layout

@Html.Partial("TestSnew")

Answer 1

You are sending a Model of Snews (plural) , when your view is expecting just one Snew.

Try this:

var snew = db.Snews.FirstOrDefault();

When you are in the context of a View, you are expected to have your information ready to be displayed.

You did that in your fist example PartialView(snew) when retrieving from your DB and sending it to the View.

But in your second example you are already on the view, so here you have to create your Snew object, so let’s suppose that Snew Class is simple and it has two properties, something like:

public class Snew {
  public String Title { get; set;}
  public String Description { get; set;}
}

So within the context of your View, you have to populate the object yourself to send it to HtmlPartial, something like this:

 @{
   var mySnew = new Snew { Title="Title created dynamically", Description="something else"};

  //now that you have the model (the Snew), you can use Partial

  Html.Partial("SnewTest",mySnew);
 }

NOTE make sure you reference the Snew class correctly with the using statement in your view

hope it helps,
