Passing database data to _loginPartial.cshtml

I am trying to pass a the number of products that are added to the shopping card

it needs to show in the _loginPartial.cshtml Top header bar

but it seems more complicated than i thought

@{
var userid = HttpContext.Request.Cookies["Shopping-card"];
string getcount = _context.shoppingCard.Where(x => x.ClientId == Guid.Parse(userid)).Count().ToString();
}
class="navbar-nav">
class="nav-item">
class="nav-link text-dark" asp-controller="Home" asp-action="Checkout"> Shoppingcard @getcount

Im getting a error on the "HttpContext"

so i tried to create a function in the controller and then pass it into the _loginPartial.cshtml

public string getShoppingbackcount()
{
var userid = HttpContext.Request.Cookies["Shopping-card"];
string getcount = _context.shoppingCard.Where(x => x.ClientId == Guid.Parse(userid)).Count().ToString();
return getcount;
}

That did not work either. even when i use the @using Webshop.Controllers;

im getting allot of error saying that "getShoppingbackcount()" does not exist

I am out of ideas to get database date passed to the _loginPartial.cshtml

Hi Osyris, for your recent query, please check below link.

https://stackoverflow.com/questions/48151797/how-to-pass-an-ienumerable-model-to-a-partial-view-in-mvc

with Viewbag i manage it to make it work but i would like to know how to pass a IEnumerable list to the _loginPartial.cshtml

something like this:

@inject ApplicationDbContext _context
@{
var userid = HttpContext.Request.Cookies["Shopping-card"];
var ProductInShoppingcard = _context.shoppingCard.Where(x => x.ClientId == Guid.Parse(userid));
}
class="navbar-nav">
class="dropdown2">
class="dropbutton">Shoppingcard @ViewBag.CountShoppingCard
class="dropdown-content">
@foreach (var product in ProductInShoppingcard)
{
"">@product.ProductTitle | @product.Amount | @product.ProductPrice
}

when products are added then save the count in Session then easily read that in your partial view.

public void AddProducts()
{
var userid = HttpContext.Request.Cookies["Shopping-card"];
string getcount = _context.shoppingCard.Where(x => x.ClientId == Guid.Parse(userid)).Count().ToString();
Session["Count"]=getCount;
}
// partial view
@session["Count"].ToString();

Attach ViewModel with _loginPartial.cshtml

Mark answer as accepted if helpful

Hi, you can use ViewBag or ViewData or TampData.

In your controller action, you can set your Count in ViewBag and in your partial view you can show it.

Sample code for ViewBag

public ActionResult Index()
{
var userid = HttpContext.Request.Cookies["Shopping-card"];
string getcount = _context.shoppingCard.Where(x => x.ClientId == Guid.Parse(userid)).Count().ToString();
ViewBag.count = getcount;
return View();
}

There are different ways. you can check below link
