demo:
<div id="exampleWrap">
        <script>$("#exampleWrap").css("visibility", "hidden");</script>

        @{
            <div id="example">
                @RenderBody()
            </div>

            if (ViewBag.Description != null)
            {
                <div class="box demo-description wide">
                    <h4>Description</h4>
                    @Html.Raw(ViewBag.Description)
                </div>
            }
        }
        <script>
            $(function(){ $("#exampleWrap").css("visibility", ""); });
        </script>
    </div>
But in the data show that before the emergence of white
How can you determine the data( @RenderBody()) before the end of the load with the progress bar displayed, the data hidden after the progress bar?

Please refer to the screen cast link below.  During inline editing when the time column is clicked to begin editing the existing time is cleared.  Also after the time and then entering the am pm designator the time is cleared and the editor closes.  Entering a time is actually only possible when the DateTime model property is marked as nullable otherwise a validation error is thrown.  (All in the video)

Grid:

@(Html.Kendo().Grid<Aero.Models.Leg>()
    .Name("grid")
    .Columns(columns =>
    {
        columns.Bound(p => p.FlightID);    
        columns.Bound(p => p.Origin);
        columns.Bound(p => p.Destination);
        columns.Bound(p => p.Start); 
        columns.Bound(p => p.TakeOff);
        columns.Bound(p => p.Landing);
        columns.Bound(p => p.Stop);
    })
    .ToolBar(toolBar =>
    {
        toolBar.Save();
        toolBar.Create();
    })
    .Editable(editable => editable.Mode(GridEditMode.InCell))
    .Scrollable()
    .Resizable(resize => resize.Columns(true))
    .HtmlAttributes(new { style = "height:430px;" })
    .DataSource(dataSource => dataSource
        .Ajax()
        .Batch(true)
        .PageSize(20)
        .ServerOperation(false)  
        .Model(model =>
        {
            model.Id(p => p.LegID);
            model.Field(p => p.LegID).Editable(false);         
        })
        .Read(read => read.Action("Legs_Read", "Test", new {  id = Model.FlightID }))
        .Update(update => update.Action("Legs_Update", "Test"))
        //.Create(create => create.Action("ForeignKeyColumn_Create", "Grid"))
        //.Destroy(destroy => destroy.Action("ForeignKeyColumn_Destroy", "Grid"))
    ).Deferred()
)

 

Model:

   public class Leg

    {
        public int LegID { get; set; }

        [DataType(DataType.Time)]     
        public DateTime? Start { get; set; }

        [DataType(DataType.Time)]  
        public DateTime? Stop { get; set; }

        [DataType(DataType.Time)]
         public DateTime TakeOff { get; set; }

        [DataType(DataType.Time)]       
        public DateTime Landing { get; set; } 

        public string Origin { get; set; }
        public string Destination { get; set; }

        public string Notes { get; set; }

        [Display(Name = "Flight")]
        public int? FlightID { get; set; }
        public virtual Flight Flight { get; set; }
    }

How in core do we add the "All" page size option, there is no list<object> overload it just wants an array of ints.

Hello,
I am trying use this example http://demos.telerik.com/aspnet-core/grid/detailtemplate to insert a grid within another grid. However, I am getting an error of "Invalid Tempate". I have included a screen shot of both the error and the code I am using for the grid.

Im using 3 tier.

1 presenter

2 service (webapi & service business logic layer)

3 data access

this is my presenter code

@(Html.Kendo().Grid<ParkingRevenueViewModel>()
  .Name("grid")
  .Columns(columns =>
  {
      columns.Bound(p => p.ParkDate).Width(20).Title("Date").Format("{0:dd/MM/yyyy}").Filterable(true);
      columns.Bound(p => p.VehRegNbr).Width(100).Title("Vehicle No");
      columns.Bound(p => p.RoadName).Width(150).Title("Road").Filterable(false);
      columns.Bound(p => p.LotNo).Width(50).Title("Lot No");
      columns.Bound(p => p.StartTime).Width(100).Title("Parking Time").Format("{0:dd/MM/yyyy h:mm:ss tt}").Filterable(false);
      columns.Bound(p => p.Value).Width(50).Title("Value").Filterable(false);
  })
  .Filterable()
    .Pageable()
 
    .DataSource(dataSource =>
    dataSource
    .WebApi()
        .Aggregates(aggregates =>
        {
            aggregates.Add(p => p.Value).Sum();
        })
    .Events(events => events.Error("error_handler"))
    ).Deferred()
        )
 

 

this is my webapi code

[HttpGet("ParkingRevenueByMonth")]
        public DataSourceResult ParkingRevenueByMonth([DataSourceRequest]DataSourceRequest request, int? Month = 0)
        {
            var model = reportsService.GetParkingRevenueByMonth(request, Month);
            return model;
        }

 

service layer

public DataSourceResult GetParkingRevenueByMonth(DataSourceRequest request, int? Month=0)
        {
 
            var now = DateTime.Now.ConvertToMalaysiaTime();
            if (Month == null || Month == 0)
            {
                Month = now.Month;
            }
            var firstOfMonth = new DateTime(now.Year, (int)Month, 1);
            var endOfMonth = firstOfMonth.AddMonths(1).AddMilliseconds(-1);
 
            var list = unitOfWork.GetRepository<ParkTable>().GetAll().Where(w=> firstOfMonth.Date <= w.TimeStart.Date && w.TimeStart.Date <= endOfMonth.Date);
            var returnModel = list.Select(s => new ParkingRevenueViewModel
 
            {
                ParkDate = s.TimeStart.Date,
                VehRegNbr = s.VehRegNbr,
                LotNo = s.GeoRoadParkLot.GeoParkLot.LotNo,
                RoadName = s.GeoRoadParkLot.GeoRoad.Description,
                StartTime = s.TimeStart,
                Value = s.Amount
            });
 
            return returnModel.ToDataSourceResult(request);
        }

 

the error thrown

I am using the Kendo DateInput inside my razor views as below

 <span>Date of Birth</span>
    @(Html.Kendo().DateInput().Name("Patient.Dob").Format("dd-MMM-yyyy").Min(new DateTime(1900, 1, 1))
             .Max(DateTime.Today).Messages(m => m.Year("yyyy").Day("dd").Month("mmm")))
 
When the date of birth is not entered, the model state validation fails as it tries to validate the placeholder value - ("dd-MMM-yyyy")

How can i specify the placeholder, such that it does not do model state validation
