Filtering in React TreeGrid component

24 Jun 2022 / 12 minutes to read

Filtering allows you to view specific or related records based on filter criteria. To enable filtering in the TreeGrid, set the allowFiltering to true. Filtering options can be configured through filterSettings.

To use filter, inject the Filter module in the treegrid.

To get start quickly with filtering functionalities, you can check on this video:

import { ColumnDirective, ColumnsDirective, Filter, Inject, TreeGridComponent } from '@syncfusion/ej2-react-treegrid';
import * as React from 'react';
import './App.css';
import { sampleData } from './datasource';
export default class App extends React.Component {
    render() {
        return <TreeGridComponent dataSource={sampleData} treeColumnIndex={1} childMapping='subtasks' height='275' allowFiltering={true}>
            <ColumnsDirective>
              <ColumnDirective field='taskID' headerText='Task ID' width='75' textAlign='Right'/>
              <ColumnDirective field='taskName' headerText='Task Name' width='180'/>
              <ColumnDirective field='startDate' headerText='Start Date' width='90' format='yMd' textAlign='Right' type='date'/>
              <ColumnDirective field='duration' headerText='Duration' width='80' textAlign='Right'/>
            </ColumnsDirective>
            <Inject services={[Filter]}/>
        </TreeGridComponent>;
    }
}

import { ColumnDirective, ColumnsDirective, Filter, Inject, TreeGridComponent } from '@syncfusion/ej2-react-treegrid';
import * as React from 'react';
import './App.css';
import { sampleData } from './datasource';

export default class App extends React.Component<{}, {}>{
    public render() {
        return <TreeGridComponent dataSource={sampleData} treeColumnIndex={1} childMapping='subtasks' height='275' allowFiltering={true}>
            <ColumnsDirective>
              <ColumnDirective field='taskID' headerText='Task ID' width='75' textAlign='Right'/>
              <ColumnDirective field='taskName' headerText='Task Name' width='180'/>
              <ColumnDirective field='startDate' headerText='Start Date' width='90' format='yMd' textAlign='Right' type='date' />
              <ColumnDirective field='duration' headerText='Duration' width='80' textAlign='Right' />
            </ColumnsDirective>
            <Inject services={[Filter]}/>
        </TreeGridComponent>
    }
}

You can apply and clear filtering by using filterByColumn and clearFiltering methods.

To disable filtering for a particular column, set columns.allowFiltering to false.

Filter Hierarchy Modes

TreeGrid provides support for a set of filtering modes with filterSettings.filterHierarchyMode property. The below are the type of filter mode available in TreeGrid.

Parent : This is the default filter hierarchy mode in TreeGrid. The filtered records are displayed with its parent records, if the filtered records not have any parent record then the filtered records only displayed.
Child : The filtered records are displayed with its child record, if the filtered records not have any child record then the filtered records only displayed.
Both : The filtered records are displayed with its both parent and child record, if the filtered records not have any parent and child record then the filtered records only displayed.
None : The filtered records are only displayed.

Initial filter

To apply the filter at initial rendering, set the filter predicate object in filterSettings.columns.

Filter operators

The filter operator for a column can be defined in the operator property of filterSettings.columns.

The available operators and its supported data types are:

Operator	Description	Supported Types
startswith	Checks whether the value begins with the specified value.	String
endswith	Checks whether the value ends with the specified value.	String
contains	Checks whether the value contains the specified value.	String
equal	Checks whether the value is equal to the specified value.	String \| Number \| Boolean \| Date
notequal	Checks for values not equal to the specified value.	String \| Number \| Boolean \| Date
greaterthan	Checks whether the value is greater than the specified value.	Number \| Date
greaterthanorequal	Checks whether a value is greater than or equal to the specified value.	Number \| Date
lessthan	Checks whether the value is less than the specified value.	Number \| Date
lessthanorequal	Checks whether the value is less than or equal to the specified value.	Number \| Date

By default, the filterSettings.columns.operator value is equal.

Filter bar

By setting the allowFiltering to true, the filter bar row will render next to the header, which allows you to filter data. You can filter the records with different expressions depending upon the column type.

Filter bar expressions:

You can enter the following filter expressions (operators) manually in the filter bar.

Expression	Example	Description	Column Type
=	=value	equal	Number
!=	!=value	notequal	Number
>	>value	greaterthan	Number
<	<value	lessthan	Number
>=	>=value	greaterthanorequal	Number
<=	<=value	lessthanorequal	Number
*	*value	startswith	String
%	%value	endswith	String
N/A	N/A	Equal operator will always be used for date filter.	Date
N/A	N/A	Equal operator will always be used for Boolean filter.	Boolean

Filterbar template with custom component

You can customize default filter bar component of a column by custom component using filter template.

The following example demonstrates the way to use filter template for a column when using filter bar. In the following example, the DropdownList component is used to filter duration column using filter template.

Change default filter bar operator

You can change the default filter operator by extending filterModule.filterOperators property in dataBound event.

In the following sample, we have changed the default operator for string typed columns as contains from startsWith.

You can enable filter menu by setting the filterSettings.type as Menu. The filter menu UI will be rendered based on its column type, which allows you to filter data. You can filter the records with different operators.

allowFiltering must be set as true to enable filter menu.

Setting columns.allowFiltering as false will prevent filter menu rendering for a particular column.

You can customize default filter menu component of a column by custom component using filterTemplate.

The following example demonstrates the way to use filter template for a column when using filter menu. In the following example, the DropdownList component is used to filter duration column using filterTemplate.

import { Inject, TreeGrid, TreeGridComponent } from '@syncfusion/ej2-react-treegrid';
import * as React from 'react';
import './App.css';
import { sampleData } from './datasource';

export default class App extends React.Component<{}, {}>{
public treegrid: TreeGrid | null;
public FilterOptions: FilterSettingsModel = {
    type: 'Menu'
};
public templateOptions(props:any): any {
    const dataSource: number[] = [1,3,4,5,6,8,9];
    return (<DropDownListComponent id={props.column.field} popupHeight='250px' dataSource={dataSource} /> );
}

public render() {
    this.templateOptions = this.templateOptions.bind(this);
    return <TreeGridComponent dataSource={sampleData} treeColumnIndex={1} filterSettings={this.FilterOptions} childMapping='subtasks' height='275' allowFiltering='true' ref={treegrid => this.treegrid = treegrid}>
        <ColumnsDirective>
          <ColumnDirective field='taskID' headerText='Task ID' width='75' textAlign='Right'/>
          <ColumnDirective field='taskName' headerText='Task Name' width='180'/>

You can use both Menu and Excel filter in a same TreeGrid. To do so, set the column.filter.type as Menu or Excel.

In the following sample menu filter is enabled by default and excel filter is enabled for the Task Name column using the column.filter.type.

Change default filter operator

You can change the default excel-filter operator by changing the column operator as contains from startsWith in the actionBegin event

Diacritics

By default, treegrid ignores diacritic characters while filtering. To include diacritic characters, set the filterSettings.ignoreAccent as true.

In the following sample, type aero in Name column to filter diacritic characters.
