Here My Classes
public class EmployeeProjectMaster
{
public int EmployeeProjectMasterId { get; set; }
//Class Variables
//Here i wants to get list of EmployeeProjectTransaction
//this is the way i tried
public EmployeeProjectMasterModelClient()
{
this.EmployeeProjectTransactionModel = new HashSet<EmployeeProjectTransactionModelClient>();
}
public virtual IEnumerable<EmployeeProjectTransactionModelClient> EmployeeProjectTransactionModel { get; set; }
}
public class EmployeeProjectTransaction
{
public int EmployeeProjecTransactiontId { get; set; }
public int EmployeeProjectMasterId { get; set; }
public int EmployeeId { get; set; }
public string EmployeeName {get;set;}
//Class Variables
}
public class Employee
{
public int EmployeeId { get; set; }
public string Employeefullname {get;set;}
}
Then here my linq query
//Get All Employee Project Details To Grid
public ActionResult GetAllEmployeeProjectDetails()
{
//DataTable Parameter
var draw = Request.Form.GetValues("draw").FirstOrDefault();
//Paging parameter
var start = Request.Form.GetValues("start").FirstOrDefault();
var length = Request.Form.GetValues("length").FirstOrDefault();
//Paging parameter
var sortColumn = Request.Form.GetValues("columns[" + Request.Form.GetValues("order[0][column]").FirstOrDefault() + "][name]").FirstOrDefault();
var sortColumnDir = Request.Form.GetValues("order[0][dir]").FirstOrDefault();
//filter parameter
var searchValue = Request.Form.GetValues("search[value]").FirstOrDefault();
List<EmployeeProjectMasterModelClient> allEmployeeProject = new List<EmployeeProjectMasterModelClient>();
int pageSize = length != null ? Convert.ToInt32(length) : 0;
int skip = start != null ? Convert.ToInt32(start) : 0;
int recordsTotal = 0;
//Database Query
using (InnoESolutionsDbEntities oInnoESolutionsDbEntities = new InnoESolutionsDbEntities())
{
var v = (from Epmm in oInnoESolutionsDbEntities.EmployeeProjectMasterModels
join Eptm in oInnoESolutionsDbEntities.EmployeeProjectTransactionModels
on Epmm.EmployeeProjectMasterId equals Eptm.EmployeeProjectMasterId
select new {Epmm, Eptm});
if (!string.IsNullOrEmpty(searchValue))
{
v = v.Where(b =>
b.Epmm.ProjectModel.ProjectName.Contains(searchValue)
);
}
if (!(string.IsNullOrEmpty(sortColumn) && string.IsNullOrEmpty(sortColumnDir)))
{
//for make sort simpler we will add system.linq.dynamic reference
//v = v.OrderBy(sortColumn + " " + sortColumnDir);
v = v.OrderBy(a => a.Epmm.EmployeeProjectMasterId + " " + a.Eptm.EmployeeProjectMasterId);
}
recordsTotal = v.Count();
allEmployeeProject = v.Skip(skip).Take(pageSize).Where(y => y.Epmm.IsActive && !y.Epmm.IsDelete && y.Eptm.IsActive && !y.Eptm.IsDelete).Select(x => new EmployeeProjectMasterModelClient
{
EmployeeProjectMasterId = x.Epmm.EmployeeProjectMasterId,
ProjectId = x.Epmm.ProjectId,
ProjectName = x.Epmm.ProjectModel.ProjectName,
WorkDateS = SqlFunctions.DateName("day", x.Epmm.WorkDate) + "/ " + SqlFunctions.DateName("month", x.Epmm.WorkDate) + "/ " + SqlFunctions.DateName("year", x.Epmm.WorkDate),
SalaryForEachEmployee = x.Epmm.SalaryForEachEmployee,
EmployeeProjectTransactionModel = *************************************How to Load Trnsaction Details As A list Here
}).ToList();
}
return Json(new { draw = draw, recordsFiltered = recordsTotal, recordsTotal = recordsTotal, data = allEmployeeProject });
}
Above c# function and Linq query for load angular data table. it's needs to select List Inside a List. i Wrote linq query for join. I don't know whether If it is correct or not.when you answer my question please consider that query. Have tried lot of time but i have failed. in query when i try to get record into allEmployeeProject . how to load transaction Details As a list inside allEmployeeProject list asterisk symbol indicates what i need to do. i wants list of employee for particular master record.
Here output what i want
MasterId | TransactionId |Employee Id | Employee Name
---------+---------------+------------+---------------
1 | 1 | 4 | name 1
| 2 | 2 | name 3
I think what you need is GroupBy method.
allEmployeeProject = v.Skip(skip).Take(pageSize).Where(y => y.Epmm.IsActive && !y.Epmm.IsDelete && y.Eptm.IsActive && !y.Eptm.IsDelete).Select(x => new EmployeeProjectMasterModelClient
{
EmployeeProjectMasterId = x.Epmm.EmployeeProjectMasterId,
ProjectId = x.Epmm.ProjectId,
ProjectName = x.Epmm.ProjectModel.ProjectName,
WorkDateS = SqlFunctions.DateName("day", x.Epmm.WorkDate) + "/ " + SqlFunctions.DateName("month", x.Epmm.WorkDate) + "/ " + SqlFunctions.DateName("year", x.Epmm.WorkDate),
SalaryForEachEmployee = x.Epmm.SalaryForEachEmployee
});
var allEmployeeProjectsByMaster = allEmployeeProject.GroupBy(x => x.EmployeeProjectMasterId).ToList();
Now you can have transaction list grouped by EmployeeProjectMaster with allEmployeeProjectsByMaster variable, just map it to relevant data model using Select .
