Exploring the power of Partial Views in ASP.NET MVC 4 with Ajax.ActionLink

On my homepage, I am attempting to incorporate links that will render partial views - revealing information from the database when clicked. I want the link to be replaced by text on the same page. Despite following a tutorial, I am facing challenges in getting it to work within my project. Below is the code snippets I have:

The Home/Index view snippet:

<div id="NeZaman">
@Ajax.ActionLink("Ne Zaman Gelcekmiş?", "NeZaman", new AjaxOptions {
                                        UpdateTargetId="NeZaman",
                                        InsertionMode = InsertionMode.Replace,
                                        HttpMethod="GET" })
</div>

The HomeController snippet:

    private CaglaContext db = new CaglaContext();

    public PartialViewResult NeZaman()
    {
        var neZaman = db.Caglas.Where(c => c.Id == 1).Select(c => c.NeZamanGelcek).FirstOrDefault();
        return PartialView("_NeZaman", neZaman);
    }

The partial view (_NeZaman.cshtml) snippet:

    @model caglageldimi.Models.Cagla

<p>
   @Model.NeZamanGelcek
</p>

The Model (Cagla.cs) snippet:

public class Cagla
{
    public int Id { get; set; }
    public bool GeldiMi { get; set; }
    public string NeZamanGelcek { get; set; }
    public string Nerdeymis { get; set; }
}

Currently, I am passing a value for neZaman which the partial view is expected to utilize, but how exactly?

Answer №1

You've assigned the model of your partial view to be of type:

caglageldimi.Models.Cagla

However, you are passing a string instead:

db.Caglas.Where(c => c.Id == 1).Select(c => c.NeZamanGelcek).FirstOrDefault();

Your select statement is only fetching the value of the "NeZamanGelcek" string property to display in your partial view.

To resolve this issue, update the model of your partial view to System.String:

@model System.String
