Problem Statement: I'm trying to bind Multi-table data from db to view using Linq query which is taking more time.I'm having around 10000 records in db.Someone suggested to use the IQueryable instead of IEnumerable,but does it affect my current code(In both View and Controller)?? Or without using that can I accomplish this??
What I should do in-order to increase the performance of loading the result?? What I'm doing wrong?? Please suggest me some better way of doing this...
Controller:
public ActionResult Index()
{
var result = (from pr in db.Prod.AsEnumerable()
join s in db.Shift.AsEnumerable() on pr.Shift equals s.ShiftID
join m in db.Module.AsEnumerable() on pr.Module equals m.ModuleID
select new GlobalModel()
{
prodModelIndex = pr,
prodModel = prodModel,
shiftModel = s,
moduleModel = m,
ddlShift = objTransactionGeneralController.GetAllShift(),
ddlModule = objTransactionGeneralController.GetAllModule()
}).ToList();
return PartialView(result);
}
public TransGeneralModel GetAllModule()
{
objTransGeneralModel.ddlModule = (from m in db.Module.AsEnumerable()
select new SelectListItem
{
Value = m.ModuleID.ToString(),
Text = m.ModuleName,
}).ToList();
return objTransGeneralModel;
}
public TransGeneralModel GetAllShift()
{
objTransGeneralModel.ddlShift = (from s in db.Shift.AsEnumerable()
select new SelectListItem
{
Value = s.ShiftID.ToString(),
Text = s.ShiftName,
}).ToList();
return objTranGeneralModel;
}
View:
@model IEnumerable<SIA.Models.Trans.GlobalModel>
@using GridMvc.Html
@{
Layout = "~/Views/Shared/_Layout.cshtml";
ViewBag.Title = "Index";

First, when you call a method like ToList(), AsEnumerable() or FirstOrDefault(), it will execute the query on the database. In your case, would be nice to remove them to hit a single query with joins.
var result = (from pr in db.Prod
join s in db.Shift on pr.Shift equals s.ShiftID
join m in db.Module on pr.Module equals m.ModuleID
select new GlobalModel()
{
prodModelIndex = pr,
prodModel = prodModel,
shiftModel = s,
moduleModel = m
}).ToList();
