reference a passed string parameter to partial view

Question

I want to pass a string variable to a partial view but im not sure how to display the string parameter to the partial view. I tried some answers i found on similar questions but i got the following output:

"my_app.Models.DogTreatments" . Can anyone tell me why is that?

Here is my code:

Controller:

[HttpPost]
    public ActionResult CasIndex(int Sid)
    {

        string treat = dbContext.DogTreatments.Where(x => x.Sid == Sid).SingleOrDefault().ToString();




        //  ViewBag.TList = dbContext.DogTreatments.Where(x => x.Sid == Sid);

        return PartialView("DisplayTreatments", treat);
    }

View page:

@Html.Partial("~/Views/Shared/DisplayTreatments.cshtml")

Partial view:

@model string

@{
    Layout = null;
}

@Model

What you see is correct because of your LINQ statement.

string treat = dbContext.DogTreatments.Where(x => x.Sid == Sid).SingleOrDefault().ToString();

This dbContext.DogTreatments.Where(x => x.Sid == Sid) filters all the DogTreatments Where x.Sid == Sid

This .SingleOrDefault() selects a single object of type DogTreatments or default(null).

The toString() will convert the object type to its string format hence my_app.Models.DogTreatments

Perhaps this would satisfies your requirement:

Return the object from LINQ query:

var treat = dbContext.DogTreatments.Where(x => x.Sid == Sid).SingleOrDefault();
return PartialView("DisplayTreatments", treat);

The Partial View will look like:

@using my_app.Models.DogTreatments //(this might need to be fixed)
@model DogTreatments

@{
    Layout = null;
}

// in here you can access the DogTreatments object
// These are just examples as I don't know from question what DogTreatments properties are
   @if(Model != null) 
   {
    @Model.Name 
    @Model.Treatment
   }
