JavaScript/jQuery FilterBuilder API
The FilterBuilder widget allows a user to build complex filter expressions with an unlimited number of filter conditions, combined by logical operations using the UI.
DevExtreme widgets are integrated with many popular libraries and frameworks. See the Installation section (for JavaScript libraries) or the Prerequisites and Installation section (for ASP.NET MVC framework) to find details on setting up DevExtreme with a particular library or framework.
The following code shows how to create the FilterBuilder widget using every supported library and framework. For more details on working with widgets in these libraries and frameworks, see the Widget Basics topic for jQuery, Angular, AngularJS, Knockout or ASP.NET MVC.
jQuery
$(function () { $("#filterBuilder").dxFilterBuilder({ value: ["Category", "contains", "Tel"], fields: [{ dataField: "Category" }, { dataField: "Shipped", caption: "Shipment Date", dataType: "date" }, { dataField: "UnitPrice", dataType: "number" }] }); });
<div id="filterBuilder"></div>
Angular
<dx-filter-builder [value]='["Category", "contains", "Tel"]'> <dxi-field dataField="Category"> </dxi-field> <dxi-field dataField="Shipped" caption="Shipment Date" dataType="date"> </dxi-field> <dxi-field dataField="UnitPrice" dataType="number"> </dxi-field> </dx-filter-builder>
import { DxFilterBuilderModule } from "devextreme-angular"; // ... export class AppComponent { // ... } @NgModule({ imports: [ // ... DxFilterBuilderModule ], // ... })
AngularJS
<div ng-controller="DemoController"> <div dx-filter-builder="{ value: ['Category', 'contains', 'Tel'], fields: [{ dataField: 'Category' }, { dataField: 'Shipped', caption: 'Shipment Date', dataType: 'date' }, { dataField: 'UnitPrice', dataType: 'number' }] }"></div> </div>
Knockout
<div data-bind="dxFilterBuilder: { value: ['Category', 'contains', 'Tel'], fields: [{ dataField: 'Category' }, { dataField: 'Shipped', caption: 'Shipment Date', dataType: 'date' }, { dataField: 'UnitPrice', dataType: 'number' }] }"></div>
ASP.NET MVC Controls
@(Html.DevExtreme().FilterBuilder() .ID("filterBuilder") .Value(new object[] { "CompanyName", "contains", "Tel" }) .Fields(fields => { fields.Add().DataField("CompanyName"); fields.Add().DataField("City") .Caption("Shipment Date") .DataType(FilterBuilderFieldDataType.Date); fields.Add().DataField("State") .DataType(FilterBuilderFieldDataType.Number); }) )
@(Html.DevExtreme().FilterBuilder() _ .ID("filterBuilder") _ .Value(New String() {"CompanyName", "contains", "Tel"}) _ .Fields(Sub(fields) fields.Add().DataField("CompanyName") fields.Add().DataField("City") _ .Caption("Shipment Date") _ .DataType(FilterBuilderFieldDataType.Date) fields.Add().DataField("State") _ .DataType(FilterBuilderFieldDataType.Number) End Sub) )
