KendoUI Date field is not filtering. It's Making grid blank - kendo-ui

Question

I tried with sample data using below JS code:
$(document).ready(function () {
var PraksysDateFormats = ["dd-MM-yyyy", "dd/MM/yyyy", "dd-MM-yy", "dd/MM/yy", "dd.MM.yy", "ddMMyy", "ddMM", "dd.MM.yyyy", "ddMMyyyy"];
relationDataSource = new kendo.data.DataSource({
data: [
{ ProductName: "Computer", UnitPrice: 100, UnitsInStock: 5, Discontinued: false, FromDate: new Date(kendo.toString(kendo.parseDate("10-11-2016", 'dd-MM-yyyy'), 'yyyy-MM-dd')), ToDate: new Date(kendo.toString(kendo.parseDate("11-11-2016", 'dd-MM-yyyy'), 'yyyy-MM-dd')) },
{ ProductName: "TV", UnitPrice: 1000, UnitsInStock: 5, Discontinued: false, FromDate: new Date(kendo.toString(kendo.parseDate("20-10-2016", 'dd-MM-yyyy'), 'yyyy-MM-dd')), ToDate: new Date(kendo.toString(kendo.parseDate("22-10-2016", 'dd-MM-yyyy'), 'yyyy-MM-dd')) },
],
schema: {
model: {
fields: {
ProductName: { type: "string" },
UnitPrice: { type: "number" },
UnitsInStock: { type: "number" },
Discontinued: { type: "boolean" },
FromDate: { type: "date" },
ToDate: { type: "date" }
}
}
},
});
var grid = $("#grid").kendoGrid({
dataSource: relationDataSource,
scrollable: true,
sortable: true,
//editable: true,
filterable: true,
columns: [
{ field: "ProductName", title: "Product Name" },
{ field: "UnitPrice", title: "Unit Price", format: "{0:c}" },
{ field: "UnitsInStock", title: "Units In Stock" },
{ field: "Discontinued", title: "Discontinued" },
{
field: "FromDate", title: "From Date", editor: FromDatePicker, width: 200, format: "{0:dd-MM-yyyy}", filterable: {
ui: dateFilter
}
},
{
field: "ToDate", title: "To Date", editor: ToDatePicker, width: 200, format: "{0:dd-MM-yyyy}", filterable: {
ui: dateFilter
}
}
],
edit: function (e) {
var grid = this;
var fieldName = grid.columns[e.container.index()].field;
// alert(fieldName)
},
save: function (e) {
var grid = this;
var fieldName = grid.columns[e.container.index()].field;
// alert(e.container.index());
// alert(fieldName)
var productName = e.values.ProductName || e.model.ProductName;
var relation = e.values.Relation || e.model.Relation;
var dataItem = this.dataSource.getByUid(e.model.uid);
dataItem.set("ProductName", productName);
dataItem.set("UnitPrice", 9000);
dataItem.set("UnitsInStock", 99);
dataItem.set("Discontinued", true);
},
update: function (e) {
alert("Update")
}
}).data("kendoGrid");
function FromDatePicker(container, options) {
alert(options.field);
$('<input id="BrugergyldigFradato" name="FromDate" dynamicfield="71" data-bind="value:' + options.field + '"/>')
.appendTo(container)
.kendoDatePicker({
format: "dd-MM-yyyy",
parseFormats: PraksysDateFormats,
culture: "da-DK"
});
$('<span class="k-invalid-msg" data-for="FromDate"></span>').appendTo(container);
};
function ToDatePicker(container, options) {
alert(options.field);
$('<input id="BrugergyldigTildato" name="ToDate" dynamicfield="71" data-bind="value:' + options.field + '"/>')
.appendTo(container)
.kendoDatePicker({
format: "dd-MM-yyyy",
parseFormats: PraksysDateFormats,
culture: "da-DK"
});
$('<span class="k-invalid-msg" data-for="ToDate"></span>').appendTo(container);
};
function dateFilter(element) {
element.kendoDatePicker({
format: "dd-MM-yyyy",
culture: "da-DK"
});
};
});
I am able to filter all columns, except last 2 date fields. On entering a date field filter value, it's making the grid blank. My date format is "dd-MM-yyyy". Any clue here would be appreciated.

Answer 1

Don't use new Date in your datasource.
On my browser(chrome):
new Date("2016-11-11")
Fri Nov 11 2016 02:00:00 GMT+0200
As you see date is converted to local time here. But when you filter with 11-11-2016 your filter will not be converted. In that case your filter value will be
Fri Nov 11 2016 00:00:00 GMT+0200
Therefore equality check fails.
Instead you can use only kendo.parseDate to assign your date values and it will work.
data: [
{ ProductName: "Computer", UnitPrice: 100, UnitsInStock: 5, Discontinued: false, FromDate: kendo.parseDate("10-11-2016", 'dd-MM-yyyy'), ToDate: kendo.parseDate("11-11-2016", 'dd-MM-yyyy') },
{ ProductName: "TV", UnitPrice: 1000, UnitsInStock: 5, Discontinued: false, FromDate: kendo.parseDate("20-10-2016", 'dd-MM-yyyy'), ToDate: kendo.parseDate("22-10-2016", 'dd-MM-yyyy') },
],

This turnout to be a formatting issue and now working as expected
