I am trying to implement the scheduler control to show live calculation of material usage on daily bases (in a week by week view).
I am unable to have the Usage data displayed in the cells although I managed to have to Materials displayed on the left hand side. I wonder if any one could help or give me some hints on what I am doing wrong. Here is my code so far:
I can be sure that data is being return to the view but the view is not showing the usage data, which is simply numeric values corresponding to a material on a specific day of the week. I have also attached a screenshot of how it looks like:
the Controller method to read the data:
public JsonResult Read([DataSourceRequest] DataSourceRequest request)
{
try
{
var usageList = new List<ReportUsageViewModel>();
var imports = _importRespository.GetImports();
foreach (var usageReportStoredProcedure in imports)
{
var usageViewModel = new ReportUsageViewModel();
usageViewModel.MaterialID = usageReportStoredProcedure.MaterialID;
usageViewModel.Start = usageReportStoredProcedure.ScanDate;
usageViewModel.End = usageReportStoredProcedure.ScanDate;
usageViewModel.DailyUsage = usageReportStoredProcedure.UsageQuantity;
usageViewModel.Title = usageReportStoredProcedure.UsageQuantity.ToString();
usageList.Add(usageViewModel);
}
return Json(usageList.ToDataSourceResult(request));
}
catch (Exception exc)
{
ErrorHelper.WriteToEventLog(exc);
return null;
}
}
The actual control
<div id="StockViewer">
#(Html.Kendo().Scheduler<WorcesterMarble.ViewModels.ReportUsageViewModel>()
.Name("StockViewer")
.Timezone("Europe/London")
.Resources(resource => resource.Add(m => m.MaterialID)
.Title("Materials")
.Name("Materials")
.DataTextField("Name")
.DataValueField("MaterialID")
.BindTo(Model.MaertiaList))
.MajorTick(270)
.MinorTickCount(1)
.StartTime(DateTime.Now.Date.AddHours(8))
.EndTime(DateTime.Now.Date.AddHours(17))
.AllDaySlot(false)
.Date(DateTime.Now.Date)
.Editable(false)
.Views(x => x.WeekView(v =>
{
v.Footer(false);
v.Selected(true);
v.DateHeaderTemplate("<span class='k-link k-nav-day'>#=kendo.toString(date, 'ddd dd/M')#</span>");
}))
.Group(group => group.Resources("Materials").Orientation(SchedulerGroupOrientation.Vertical))
.DataSource(d => d
.Model(m => {
m.Id(f => f.MaterialID);
m.Field(f => f.Title).DefaultValue("No title");
})
.Read("Read", "ReportUsage")
)
)
Update: This is the ViewModel implementing the ISchedulerEvent
public class ReportUsageViewModel : ISchedulerEvent
{
public int MaterialID { get; set; }
public string MaterialName { get; set; }
public int? DailyUsage { get; set; }
public List<MaterialViewModel> MaertiaList { get; set; }
public string Description { get; set; }
public System.DateTime End { get; set; }
public bool IsAllDay { get; set; }
public string RecurrenceException { get; set; }
public string RecurrenceRule { get; set; }
public System.DateTime Start { get; set; }
public string Title { get; set; }
}
The issue was in these two lines:
.StartTime(DateTime.Now.Date.AddHours(8))
.EndTime(DateTime.Now.Date.AddHours(17))
The data was there but these two lines were hiding it. The data was being logged at times outside the time range of 8 to 17 so I removed these two lines and then set the Major ticks to 1440, which is the total number of ticks in 24 hrs, which helped me hiding the time column as I didn't need it..

I want to display related data from second table with each value in first table
i have tried this query
public ActionResult Index()
{
List<EmployeeAtt> empWithDate = new List<EmployeeAtt>();
var employeelist = _context.TblEmployee.ToList();
foreach (var employee in employeelist)
{
var employeeAtt = _context.AttendanceTable
.GroupBy(a => a.DateAndTime.Date)
.Select(g => new EmployeeAtt
{
Date = g.Key,
Emp_name = employee.EmployeeName,
InTime = g.Any(e => e.ScanType == "I") ? g.Where(e =>
e.ScanType == "I").Min(e =>
e.DateAndTime.ToShortTimeString())
.ToString() : "Absent",
OutTime = g.Any(e => e.ScanType == "O") ? g.Where(e =>
e.ScanType == "O").Max(e =>
e.DateAndTime.ToShortTimeString())
.ToString() : "Absent"
});
empWithDate.AddRange(employeeAtt);
}
return View(empWithDate);
}
Here is my attendance Table
AttendanceTable
Results
I want to display the shortest time with "I" Column value against each employee and last time with "O" Column value as out time. I think i am not using AddRange() at proper place. Where it should go then?
public partial class TblEmployee
{
public TblEmployee()
{
AttendanceTable = new HashSet<AttendanceTable>();
}
public int EmpId { get; set; }
public string EmployeeName { get; set; }
public virtual ICollection<AttendanceTable> AttendanceTable { get; set; }
}
public partial class AttendanceTable
{
public int Id { get; set; }
public int AttendanceId { get; set; }
public int EmployeeId { get; set; }
public string ScanType { get; set; }
public DateTime DateAndTime { get; set; }
public virtual TblEmployee Employee { get; set; }
}
The actual problem is not related to AddRange(), you need a where clause before GroupBy() to limit attendances (before grouping) to only records related to that specific employee, e.g.
_context.AttendanceTable
.Where(a => a.Employee == employee.EmployeeName)
.GroupBy(a => a.DateAndTime.Date)
...
Depended on your model, it is better to use some kind of ID instead of EmployeeName for comparison if possible.
Also you can use SelectMany() instead of for loop and AddRange() to combine the results into a single list. like this:
List<EmployeeAtt> empWithDate = _context.TblEmployee.ToList()
.SelectMany(employee =>
_context.AttendanceTable
.Where(a => a.Employee == employee.EmployeeName)
.GroupBy(a => a.DateAndTime.Date)
.Select(g => new EmployeeAtt
{
...
})
);

I am having issue of using Kendo UI scheduler,
When I schedule task ,
Kendo UI start and end date not returning on server side.
Start and end date always return default date.
Here a Razor Code :
#model IEnumerable<Web.Models.PlantColor>
#{
ViewBag.Title = "Schedule View";
}
<h2>Schedule View</h2>
#(Html.Kendo().Scheduler<WorkScheduler.Web.Models.KendoSchedular>()
.Name("scheduler")
.Date(new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day))
.StartTime(new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, 08, 00, 00))
.Height(600)
.Views(views =>
{
views.DayView();
views.WorkWeekView();
views.WeekView();
views.MonthView();
views.AgendaView();
})
.Resources(resource =>
{
resource.Add(m => m.PlantId)
.Title("Owner")
.DataTextField("Text")
.DataValueField("Value")
.DataColorField("Color")
.BindTo(Model);
})
.DataSource(d => d
.Model(m =>
{
m.Id(f => f.id);
})
.Read("ReadSchedule", "ScheduleView")
.Create("CreateSchedule", "ScheduleView")
.Destroy("Destroy", "ScheduleView")
.Update("Update", "ScheduleView")
)
)
Make sure that you have the start and end fields defined in your Model that you are posting back (and model inherits from ISchedulerEvent):
public class CalendarAppointmentViewModel : ISchedulerEvent
{
public int Id { get; set; }
public string Title { get; set; }
public string Description { get; set; }
public string Recurrence { get; set; }
public string StartTimezone { get; set; }
public string EndTimezone { get; set; }
private DateTime start;
public DateTime Start
{
get
{
return start;
}
set
{
start = value.ToUniversalTime();
}
}
private DateTime end;
public DateTime End
{
get
{
return end;
}
set
{
end = value.ToUniversalTime();
}
}
public string RecurrenceRule { get; set; }
public int? RecurrenceID { get; set; }
public string RecurrenceException { get; set; }
public bool IsAllDay { get; set; }
I can see this question is already accepted as best answer. Perhaps following might be helpful also for someone struggling to return Start/End dates from Editor of Kendo Scheduler.
I had same issue, and followed the solutions provided here, still no success. In my case defining the culture and creating a Model inherited from "ISchedulerEvent" was still returning default date to the server side in Create & Update events handler methods of the Controller.
For me problem was a missing .js file.
kendo.timezones.min.js
So for anyone who is in the same shoes like me, kindly look at your Scripts folder in the project, and if that .js file is missing.
And please follow these steps in setting up the project.
I have the following entities:
public class Mark {
public Int32 Id { get; set; }
public DateTime Created { get; set; }
public virtual ICollection<MarkLocalized> MarksLocalized { get; set; }
} // Mark
public class MarkLocalized {
public Int32 Id { get; set; }
public String Culture { get; set; }
public String Name { get; set; }
public virtual Mark Mark { get; set; }
} // MarkLocalized
Given a culture, for example "en", I need to get all Marks, their localized name for the given culture and map them to a MarkModel:
public class MarkModel {
public Int32 Id { get; set; }
public String Name { get; set; }
} // MarkModel
I tried the following:
Context context = new Context();
context.Marks
.SelectMany(x => x.MarksLocalized, (y, z) =>
new MarkModel {
Id = y.Id,
Name = z.Name,
Slug = z.Slug
});
But I need only the MarksLocalized which culture is equal to the given culture.
How can I do this?
Thank you,
Miguel
You can add Where inside SelectMany:
Context context = new Context();
context.Marks
.SelectMany(x => x.MarksLocalized.Where(x => x.Culture == "en"), (y, z) =>
new MarkModel {
Id = y.Id,
Name = z.Name,
Slug = z.Slug
});
But should be more clear with syntax query:
from m in new Context.Marks
from l in m.MarksLocalized
where l.Culture == "en"
select new MarkModel { m.ID, m.Name, l.Slug }
which should be translated into following query by compiler:
context.Marks
.SelectMany(x => x.MarksLocalized, (m, l) => new { m, l })
.Where(x => x.l.Culture == "en")
.Select(x => new MarkModel { x.m.ID, x.m.Name, x.l.Slug })
which should produce exact same results as first one.
After spending the last couple days searching, I'm officially stuck. I'm working on a binding an object to the Telerik MVC 3 Grid, but the catch is that it needs to have dynamically created columns (not auto generated). Three of the columns are known, the others are unknown, and this is the tricky part. Basically, it can be like these examples:
KnownColumn1 | KnownColumn2 | UnknownColumn1 | KnownColumn3
KnownColumn1 | KnownColumn2 | UnknownColumn1 | UnknownColumn2 | UnknownColumn3 | KnownColumn3
etc.
Because I'm putting the unknown columns in a list (I've tried a dictionary too so I can get the column names), this has complicated things for me when binding. My code is below:
Model (There can be zero to hundreds of rows, but this model is in a view model of type List, there can also be 0 to 20 plus columns that are dynamically added)
public class VendorPaymentsGLAccount
{
public string GeneralLedgerAccountNumber { get; set; }
public string GeneralLedgerAccountName { get; set; }
public string DisplayName { get { return string.Format("{0} - {1}", GeneralLedgerAccountNumber, GeneralLedgerAccountName); } }
public Dictionary<string, double> MonthAmount { get; set; }
public double Total { get { return MonthAmount.Sum(x => x.Value); } }
public List<string> Columns { get; set; }
public List<double> Amounts { get; set; }
public VendorPaymentsGLAccount() { }
}
View (The section that's commented out was trying to use the dictionary)
<fieldset>
<legend>General Ledger Account Spend History</legend>
#if (Model.VendorPaymentsGLAccounts != null)
{
<br />
#(Html.Telerik().Grid(Model.VendorPaymentsGLAccounts)
.Name("Grid")
.Columns(columns =>
{
columns.Bound(gl => gl.DisplayName).Title("General Ledger Account").Width(200).Filterable(false).Sortable(false);
//foreach (var month in Model.VendorPaymentsGLAccounts[0].MonthAmount)
//{
// //columns.Bound(gl => gl.MonthAmount[month.Key.ToString()].ToString()).Title(month.Key.ToString()).Width(100).Filterable(false).Sortable(false);
// //columns.Template(v => Html.ActionLink(v.VoucherID, "VoucherSummary", new { id = v.VoucherID, bu = v.BusinessUnitID, dtt = v.InvoiceDate.Ticks })).Title("Voucher").Width(100);
// columns.Template(gl => Html.ActionLink(gl.MonthAmount[month.Key.ToString()].ToString(), "VoucherSummary")).Title(month.Key.ToString()).Width(100);
//}
for (int i = 1; i <= (Model.VendorPaymentsGLAccounts[0].Columns.Count() - 1); i++)
{
string colTemp = Model.VendorPaymentsGLAccounts[0].Columns[i - 1];
columns.Template(gl => gl.Amounts[i - 1]).Title(colTemp).Width(100);
}
columns.Template(gl => String.Format("{0:C}", gl.Total)).Title("Total");
})
.Sortable()
.Pageable()
.Filterable()
.Footer(true))
}
else

#:There are no records that match your selected criteria.
}
</fieldset>
Using the dictionary approach, I was able to get the columns generated correctly with the right header text, but the values for the columns (in my testing there were only 2 columns) were the same. Can anyone help with this? This seems to be an oddball issue. Just trying to figure out how to do this correctly.
Update: Here is a screen shot using the dictionary approach that shows the issue. The column headings are correct, but the values are the same for both of the dynamic columns.
Using dynamically defined columns with the Telerik grid control can be tricky. But in your case, it's mainly a typical pitfall of closures.
In the following loop, the compiler will bind each instance of gl => gl.Amounts[i - 1] to the variable i and evaluate it later:
for (int i = 1; i <= (Model.VendorPaymentsGLAccounts[0].Columns.Count() - 1); i++)
{
string colTemp = Model.VendorPaymentsGLAccounts[0].Columns[i - 1];
columns.Template(gl => gl.Amounts[i - 1]).Title(colTemp).Width(100);
}
In fact, it's evaluated after the loop has finished. So i will always have the value that lead to the completion of the loop.
The fix is to use a temporary variable:
for (int i = 1; i <= (Model.VendorPaymentsGLAccounts[0].Columns.Count() - 1); i++)
{
string colTemp = Model.VendorPaymentsGLAccounts[0].Columns[i - 1];
int columnIndex = i - 1;
columns.Template(gl => gl.Amounts[columnIndex]).Title(colTemp).Width(100);
}
I had the same problem, and was googling plenty of hours around, and have done a lot of attempts from various assistance lines. But even so, it was not so trivial to solve!
And for that reason and to have also another working example here, I will provide also my solution!
Information: It only works at my place with an IList Model. Other collections had also caused problems!
#model IList<CBS.Web.Models.Equipment.EquipmentViewModel>
#(Html.Telerik().Grid(Model)
.Name("Grid")
.DataKeys(keys =>
{
keys.Add(m => m.ID);
})
.DataBinding(dataBinding =>
{
dataBinding.Ajax()
// renders the grid initially
.Select("EquipmentGrid", "Equipment");
})
.Columns(columns =>
{
// Equipment IDs
columns.Bound(m => m.ID).Hidden(true);
columns.Bound(m => m.Name).Title("Equipments").Width(200);
// Every item (EquipmentViewModel) of the Model has the same Count of Fields
for (int i = 0; i < (Model[0].Fields.Count()); i++)
{
// Name of the column is everytime same as in Model[0]
string columnName = Model[0].Fields.ElementAt(i).FieldDefinition.Name;
// Constructs i-counted columns, dynamically on how much
// Fields are owned by an Equipment. But note, that all Equipment-items
// in the Model must have the same Count and disposal of Fields!
columns.Template(m => m.Fields
.Where(f => f.FieldDefinition.Name == columnName)
.Where(f => f.EquipmentId == m.ID).First().Value)
.Title(columnName)
.Width(columnName.Length * 8); // * 8 was the optimal lenght per character
}
})
.ClientEvents(events => events.OnRowSelect("onRowSelected"))
.Selectable()
.Resizable(resizing => resizing.Columns(true))
.Pageable()
.Scrollable()
.Groupable()
.Filterable()
)
Controller:
public ActionResult EquipmentGrid(Guid id)
{
var belongingEquipments = _equipmentRepository.GetNotDeleted()
.OrderBy(e => e.Name).ToList()
.Where(e => e.RevisionId == id);
List<EquipmentViewModel> equVMList = new List<EquipmentViewModel>();
for (int i = 0; i < belongingEquipments.Count(); i++)
{
var equVM = new EquipmentViewModel
{
ID = belongingEquipments.ElementAt(i).ID,
Name = belongingEquipments.ElementAt(i).Name,
RevisionId = belongingEquipments.ElementAt(i).RevisionId,
EquipmentTypeId = belongingEquipments.ElementAt(i).EquipmentTypeId,
Fields = SortFields(belongingEquipments.ElementAt(i).Fields.ToList())
};
equVMList.Add(equVM);
}
return PartialView("EquipmentGrid", equVMList);
}
Models:
namespace CBS.Web.Models.Equipment
{
public class EquipmentViewModel
{
public Guid ID { get; set; }
public string Name { get; set; }
public Guid RevisionId { get; set; }
public Guid EquipmentTypeId { get; set; }
public virtual ICollection<FieldEntity> Fields { get; set; }
}
}
FieldDefinition
namespace CBS.DataAccess.Entities
{
public class FieldDefinitionEntity : EntityBase
{
[Required]
public virtual Guid EquipmentTypeId { get; set; }
public virtual EquipmentTypeEntity EquipmentType { get; set; }
[Required(AllowEmptyStrings = false)]
public virtual string Name { get; set; }
public virtual int Numbering { get; set; }
[Required]
public virtual Guid TypeInformationId { get; set; }
public virtual TypeInformationEntity TypeInformation { get; set; }
public virtual ICollection<FieldEntity> Fields { get; set; }

}
I dynamically bind the columns at runtime with reflection:
#model IEnumerable<object>
#using System.Collections
#using System.Collections.Generic
#using System.Reflection;
#(Html.Telerik().Grid(Model)
.Name("Grid")
.Columns(columns =>
{
Type t = Model.GetType().GetGenericArguments()[0];
foreach (var prop in t.GetProperties())
{
if (IsCoreType(prop.PropertyType))
{
columns.Bound(prop.PropertyType, prop.Name);
}
}
})
.DataBinding(binding => binding.Ajax()
.Select("SelectMethod", "SomeController")
)
.Sortable()
.Pageable()
.Filterable()
.Groupable()
)
#functions{
public bool IsCoreType(Type type)
{
if (type.IsGenericType && type.GetGenericTypeDefinition() == typeof(Nullable<>))
{
return IsCoreType(type.GetGenericArguments()[0]);
}
return !(type != typeof(object) && Type.GetTypeCode(type) == TypeCode.Object);
}
}
Here is the workaround:
#(Html.Telerik().Grid(Model.Users)
.Name("Grid")
.Columns(columns => {
columns.GenerateCustomColumns(columnSettings);
}).DataBinding(dataBinding => dataBinding.Ajax().Select("_getusers", "home"))
.Scrollable(scrolling => scrolling.Enabled(true).Height("auto"))
.Pageable(paging => paging.Enabled(true)
.PageSize(10, new int[] { 5, 10, 20, 50, 100, 500 })
.Position(GridPagerPosition.Both)
.Total(Model.Users.Count)
.Style(GridPagerStyles.PageSizeDropDown | GridPagerStyles.NextPreviousAndNumeric)
.PageTo(1))
.Filterable(filtering => filtering.Enabled(true))
.Reorderable(reordering => reordering.Columns(true))
.NoRecordsTemplate(" ")
.EnableCustomBinding(true)
)
// Extension method to genarate columns dynamically
public static class TelerikMvcGridColumnHelper
{
public static void GenerateCustomColumns<T>(this GridColumnFactory<T> columns,List<GridCustomColumnSettings> settings) where T:class
{
if (settings != null)
{
settings.ForEach(column =>
{
var boundedColumn = columns.Bound(column.Member);
if (column.ClientFooterTemplate != null)
boundedColumn.ClientFooterTemplate(column.ClientFooterTemplate);
if (!string.IsNullOrEmpty(column.Width))
boundedColumn.Width(column.Width);
});
}
}
}
// Column settings class
public class GridCustomColumnSettings : GridColumnSettings
{
public string ClientFooterTemplate { get; set; }
}
I did this simple way. NOTE : the following solution works in ajax edit mode too (not just a read-only grid) :
when the ViewModels are :
public class PriceSheetEditGridViewModel
{
public IEnumerable<PriceSheetRowViewModel> Rows { get; set; }
public IEnumerable<PriceSheetColumnViewModel> Columns { get; set; }
}
public class PriceSheetColumnViewModel
{
public int Id { get; set; }
public string Title { get; set; }
}
public class PriceSheetRowViewModel
{
public int RowNo { get; set; }
public string Description { get; set; }
public double?[] Prices { get; set; }
}
the view can be like this (part of view.cshtml file...) :
....
#model PriceSheetEditGridViewModel
...
columns.Bound(o => o.Description ).Width(150);
int i = 0;
foreach (var col in Model.Columns)
{
columns
.Bound(model => model.Prices).EditorTemplateName("PriceSheetCellPrice").EditorViewData(new { ColumnId = i })
.ClientTemplate("<span><#=Prices ? jsHelper.addCommas(Prices[" + i.ToString() + "]):null#></span>")
.Title(col.Title).Width(80);
i++;
}
....
and the PriceSheetCellPrice.cshtml editor template file (in shared\editortemplates folder) :
#model decimal?
#(Html.Telerik().NumericTextBox()
.Name(ViewData.TemplateInfo.GetFullHtmlFieldName(string.Empty)+"["+ViewBag.ColumnId+"]")
.InputHtmlAttributes(new { style = "width:100%" })
})
.EmptyMessage("")
.DecimalDigits(0)
.DecimalSeparator(",")
.MinValue(0)
.Value((double?) Model)
)
I am trying to render a Partial from within a System.Web.Helpers.WebGrid
my model class looks like this:
class GameInfo
{
public List<AppUser> Team1 { get; set; }
public List<AppUser> Team2 { get; set; }
// and more properties
}
class AppUser
{
public string PictureUrl { get; set; }
public string ProfileUrl { get; set; }
public long GamesWon { get; set; }
public long GamesLost { get; set; }
public int Points { get; set; }
// and more properties
}
I want my GridView to show a list of GameInfo's in my grid view.
What is turning out be to be tougher than expected is rendering the Teams (List).
To stay DRY I created a partial view to render a Team (_Team.cstml).
This is my razor code:
#if (Model != null)
{
var webgrid = new WebGrid(source: Model.Games,
rowsPerPage: 10);
<div id="grid">
#webgrid.GetHtml(
columns: webgrid.Columns(
webgrid.Column(header: "Score", format: #<text>#item.Score1/#item.Score1</text>),
webgrid.Column(header: "Team 1", format: (item) =>
{
return "hello sb"; // this line works!
//return Html.Partial("_Team", item.Team1); // this gives an error
})
)
)
</div>
}
Any idea how I can get this to work?
Thank you!
In case someone else runs into this, I managed to solve it this morning.
This works:
webgrid.Column(header: "Team 1", format: (item) =>
{
List<Cuarenta.Web.Models.AppUser> team = ((Cards.Cloud.WebRole.Admin.GameInfo)item.Value).Team1;
return Html.Partial("_Team", team);
})
