I generating computed values based on a time range, like this:
output
The trouble is that with many rows in takes for ever to do it.
I need to find a quicker way.
For each cell with volumes i do this:
public int GetVolume(int _month, int _year, int companyId, int NVR, string country)
{
var salesCount = 0;
salesCount = (int)(from sale in _context.SalesData.AsNoTracking()
join _company in _context.CompaniesMains.AsNoTracking() on sale.CompanyId equals _company.Id
where (sale.IYear == _year && sale.IMonth == _month) && _company.Id == companyId && sale.Nvr == NVR
&& sale.Country.Trim().Equals(country)
select sale.SalesAmount).Sum();
return salesCount;
}
And in cells with turn over i do this:
public decimal GetPrice(int _month, int _year, int NVR, string country, bool Euros = false)
{
var salesCount = 0m;
var count = (from price in _context.Prices.AsNoTracking()
where price.IYear == _year
&& price.IMonth == _month
&& price.Valuta.Equals(country)
&& price.Nvr.Equals(NVR)
select price.RegisterPrice.Trim()).FirstOrDefault();
if (count != null)
{
var style = NumberStyles.AllowDecimalPoint;
var culture = CultureInfo.CreateSpecificCulture("en-US");
Decimal.TryParse(count, style, culture, out salesCount);
}
if (Euros)
{
var currency = 0m;
switch (country)
{
case "DK":
currency = _memoryCache.GetCacheCurrency("dkk");
break;
case "NO":
currency = _memoryCache.GetCacheCurrency("nok");
break;
case "SE":
currency = _memoryCache.GetCacheCurrency("sek");
break;
case "FI":
currency = _memoryCache.GetCacheCurrency("fin");
break;
}
salesCount /= currency;
}
return (decimal)salesCount;
}
It all runs in a loop where i call the 2 methods.
foreach (var q in selectedLst)
{
if (filters.TableType == TableTypeView.Month)
{
for (var i = 0; i <= GetMonthDifference; i++)
{
var month = filters.StartDate.AddMonths(i);
var d = new Dates();
var salesAmount = GetVolume(month.Month, month.Year, q.CompanyId, q.Nvr, q.CompanyCountry);
if (filters.TurnOver)
{
var RegisterPrice = GetPrice(month.Month, month.Year, q.Nvr, q.CompanyCountry, filters.Euros);
d.TurnOver = (decimal)salesAmount * (RegisterPrice / 100);
d.RegisterPrice = RegisterPrice / 100;
}
d.Amount = (int)salesAmount;
d.Nvr = q.Nvr;
d.Month = month.Month;
d.Year = month.Year;
d.Country = q.CompanyCountry;
dates.Add(d);
}
}
}
Any ideas on how to make this quick?

args in your case is data that will be passed to a delegate specified by Action<object> parameter.
See docs.
When using overload of StartNew with Action<object>, you need to supply next argument of type object, which will be used in passed delegate.
Task.Factory.StartNew((o) => {/* 1 will be used here */}, 1, token, options, scheduler);
MSDN
The args argument (referred to as "state" in the documentation) is a parameter you need to specify when you call to Task.Factory.StartNew.
state (Object): An object containing data to be used by the action delegate.
Sample:
object param = somevalue;
Task.Factory.StartNew( (arg) =>
{ /* get the arg value here.*/
}, param);

Country: Bahrain( i am selecting)
Amount:1000
Bank charges: 100(i am entering)
Vat:5%(entering) result:50(autogenerate)
Discount:6%(entering) result:60(autogenerate)
Total:1070(autogenerate)
This is working fine.I am getting the Total(with VAT).
Country:India(i am selecting)
Amount:1000
Bank charges: 100(i am entering)
Discount:5%(entering) result:50(autogenerate)
Total:(here i am not getting the amount)(may be because i set the visibility of VAT field false)
Here i am hidding the field VAT by using vattr.Visible=false. What should i do in order to sort out this issue?
Code behind:
protected void lstCountryy_SelectedIndexChanged(object sender, EventArgs e)

{
vattr.Visible = true;
trdeclaration.Visible = false;
}
else
{
vattr.Visible = false;
trdeclaration.Visible = true;
}
}
Javascript:
function calculate(amount) {
var bankcharge = document.getElementById("<%=txtBankCharge.ClientID%>").value;

I wanted to write this condition in such a way that when use selects bahrain,vat should be visible and should be calculated.
when user selects india,vat should be hidden and will yield the total amount.
Finally i got solution.This w orked perfectly.
if (lstCountryy.SelectedValue == "U.A.E" || lstCountryy.SelectedValue == "BAHRAIN" || lstCountryy.SelectedValue == "SAUDI ARABIA")
{
txtvat.Text = "";
txtvatt.Text = "";
txtBankCharge.Text = "";
txtDiscount.Text = "";
txtDiscountText.Text = "";
txtTotal.Text = "";
vattr.Style.Add("display", "float");
trdeclaration.Visible = false;
//txtvat.Enabled = true;
}
else
{
txtvat.Text = "";
txtvatt.Text = "";
txtBankCharge.Text = "";
txtDiscount.Text = "";
txtDiscountText.Text = "";
txtTotal.Text = "";
vattr.Style.Add("display", "none");
trdeclaration.Visible = true;

The first Picture show the first grid with all values.I selected 4 for example,after the calculations of the method i need to show only the 4 select in a model (second Picture),under the first grid of Picture two i will put the new grid with the selected values from before.
