Hi nabilabolo,
Check this example. Now please take its reference and correct your code.
Model
public class ProductModel
{
public decimal Quantity { get; set; }
public decimal Cost { get; set; }
public decimal Total { get; set; }
}
Controller
public class HomeController : Controller
{
// GET: Home
public ActionResult Index()
{
return View(GetProducts());
}
[HttpPost]
public ActionResult Calculate()
{
List<ProductModel> products = GetProducts();
foreach (ProductModel product in products)
{
product.Total = Math.Round(((product.Cost / product.Quantity) * 100), 2);
}
return View("Index", products);
}
private List<ProductModel> GetProducts()
{
List<ProductModel> products = new List<ProductModel>();
products.Add(new ProductModel { Quantity = 30, Cost = 5 });
products.Add(new ProductModel { Quantity = 100, Cost = 21 });
return products;
}
}
View
@using Row_Calculation.Models;
@model IEnumerable<ProductModel>
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
</head>
<body>
<table>
<tr>
<th>Quantity</th>
<th>Cost</th>
<th>Total</th>
</tr>
@foreach (ProductModel product in Model)
{
<tr>
<td>@product.Quantity.ToString("N0")</td>
<td>@product.Cost.ToString("N0")</td>
<td>@product.Total.ToString("N0")</td>
</tr>
}
</table>
@using (Html.BeginForm("Calculate", "Home", FormMethod.Post))
{
<input type="submit" value="Calculate" />
}
</body>
</html>
