Answer 1

Try this way: Controller:

var category = (from s in context.M_ProductCategory
                                where s.ID == C_ID
                                select s.Title);
 ViewBag.cat = category.FirstOrDefault();

Index.cshtml:

@{
    Html.RenderPartial("PartialViewSpecification");
}

PartialViewSpecification.cshtml(partialView):

@ViewBag.cat

I hope this one is working...

Index.cshtml:

@{
    Html.RenderPartial("PartialViewSpecification", (string)(ViewBag.cat)); 
}

PartialViewSpecification.cshtml :

@model string

<span>Model</span>
