Dear team,
Recently I've updated the kendo UI.
currently I'm using the this version.

Here I wrote the code for testing.

// cshtml code

@(Html.Kendo().Grid<Alliant.Controllers.ProductViewModel>()
        .Name("mixedSort")
        .Columns(columns => {
            columns.Bound(o => o.ProductName).Width(300);
            columns.Bound(p => p.UnitPrice).Width(300);
            columns.Bound(p => p.UnitsInStock).Width(300);
            columns.Bound(p => p.Discontinued).Width(300);
            columns.Bound(p => p.Group).Width(300);
        })
        .Pageable(pageable => pageable.ButtonCount(5))
        .Sortable(sortable => sortable
            .AllowUnsort(true)
            .SortMode(GridSortMode.Mixed)
            .ShowIndexes(true))
        .DataSource(dataSource => dataSource
            .Ajax()
            .PageSize(5)
            .Read(read => read.Action("Sorting_Orders_Read", "Testing"))
         )
    )

// Controller code
public ActionResult Sorting_Orders_Read([DataSourceRequest] DataSourceRequest request)
{
    List<ProductViewModel> lstData = new List<ProductViewModel>()
    {
        new ProductViewModel(){Group="A",ProductName="A1",UnitPrice=10,Discontinued=1,UnitsInStock=50},
        new ProductViewModel(){Group="A",ProductName="B1",UnitPrice=20,Discontinued=2,UnitsInStock=60},
        new ProductViewModel(){Group="B",ProductName="C1",UnitPrice=30,Discontinued=3,UnitsInStock=70},
        new ProductViewModel(){Group="C",ProductName="D1",UnitPrice=40,Discontinued=4,UnitsInStock=80},
        new ProductViewModel(){Group="C",ProductName="E1",UnitPrice=50,Discontinued=5,UnitsInStock=90},
    };

    return Json(lstData.ToDataSourceResult(request), JsonRequestBehavior.AllowGet);
}

// Model
public class ProductViewModel
{
    public string ProductName { get; set; }
    public decimal UnitPrice { get; set; }
    public int UnitsInStock { get; set; }
    public decimal Discontinued { get; set; }
    public string Group { get; set; }
}
Could you please help me to figure out the issue?
I also checked the jquery code.

Hi Team,

1. Date column filter value shown full date instead of dd/MM/yyyy format. If I change the format  filter not working. 

Sample screenshot:

2. When I click on grid or some other area on the page selected filter text value like('Last month', 'Last week', 'Today', 'Yesterday') from custom date filter dropdown

Grid:

@(Html.Kendo().Grid<InteractiveReports.Model.ViewModel.UserReportResult>()
                                    .Name("userreport")

the coulm i'm talking about is the "isConq" one, i would like to show "Conq" or "Ritardo" instead of "è vero" or "è falso".

Following the doc, i'm calling the "isConQFilter" js function, but it is never triggered by the kendo.

Where am i wronged?

If you need something else, please, tell me.

I'm using kendo mvc grid version 2016.
