Sort Multiple Checkbox Filter
The following example demonstrates how to sort the Kendo UI multiple checkbox filter while using the Grid.
<div id="client"></div>
<script>
$(document).ready(function() {
var telerikWebServiceBase = "https://demos.telerik.com/kendo-ui/service/";
$("#client").kendoGrid({
dataSource: {
transport: {
read: {
url: telerikWebServiceBase + "/Products",
dataType: "jsonp"
},
update: {
url: telerikWebServiceBase + "/Products/Update",
dataType: "jsonp"
},
destroy: {
url: telerikWebServiceBase + "/Products/Destroy",
dataType: "jsonp"
},
create: {
url: telerikWebServiceBase + "/Products/Create",
dataType: "jsonp"
},
parameterMap: function(options, operation) {
if (operation !== "read" && options.models) {
return {models: kendo.stringify(options.models)};
}
}
},
batch: true,
pageSize: 20,
schema: {
model: {
id: "ProductID",
fields: {
ProductID: { editable: false, nullable: true },
ProductName: { validation: { required: true } },
UnitPrice: { type: "number", validation: { required: true, min: 1} },
Discontinued: { type: "boolean" },
UnitsInStock: { type: "number", validation: { min: 0, required: true } }
}
}
}
},
filterMenuInit: function(e) {
if (e.field === "UnitPrice" || e.field === "UnitsInStock") {
var filterMultiCheck = this.thead.find("[data-field=" + e.field + "]").data("kendoFilterMultiCheck")
filterMultiCheck.container.empty();
filterMultiCheck.checkSource.sort({field: e.field, dir: "asc"});
// uncomment the following line to handle any grouping from the original dataSource:
// filterMultiCheck.checkSource.group(null);
filterMultiCheck.checkSource.data(filterMultiCheck.checkSource.view().toJSON());
filterMultiCheck.createCheckBoxes();
}
},
filterable: true,
pageable: true,
height: 550,
toolbar: ["create", "save", "cancel"],
columns: [
{ field: "ProductName", filterable: { multi: true } },
{ field: "UnitPrice", title: "Unit Price", format: "{0:c}", width: 120, filterable: { multi: true } },
{ field: "UnitsInStock", title: "Units In Stock", width: 120, filterable: { multi: true } },
{ field: "Discontinued", width: 120, filterable: { multi: true, dataSource: [{ Discontinued: true }, { Discontinued: false }]} },

});
