What I have tried:
my Controller
public IActionResult reportPurchaseDate( DateTime datefrom, DateTime dateto)
{
bool isrole = getRole();
if (isrole == true)
{
var rpt = _Context.orderDetails.Where(c => c.masterID.Order_Kind_ID == 1 && c.masterID.DateAdded >= datefrom && c.masterID.DateAdded <= dateto)
.Include(c => c.masterID)
.Include(c => c.products.ProductName)
.Include(c => c.products.quantity)
.Include(c => c.products.price);
return View(rpt);
}
else
{
return RedirectToAction("noaccess", "HomeController");
}
}
my View
@model IEnumerable<orderdetails>
@{
ViewData["Title"] = "report purchase Date";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h1>تقرير مشتريات فترة</h1>
