    I have written below onFilter function and the results in the console are correct. However, when setting the value for setRecordNum, the jqxGrid filtering stops working. If I comment out this (setRecordNum(myGrid.current!.getdisplayrows().length)), then the filtering works fine. So, how do I set a value based on results returned from jqxGrid and have it filter the results in the grid?

    code snippets:

    const onFilter = (): void => {

    if (myGrid.current?.getrows().length != undefined) {
    console.log(myGrid.current?.getrows().length);
    console.log(myGrid.current!.getdisplayrows().length);

    setRecordNum(myGrid.current!.getdisplayrows().length);
    }

    }

    <JqxGrid
    ref={myGrid}
    theme={‘bootstrap’}
    width={‘100%’}
    source={dataAdapter}
    columns={columns as any}
    filterable={true}
    showfilterrow={false}
    filtermode={‘excel’}
    enabletooltips={true}
    sortable={true}
    onFilter={onFilter}
    />

    Hi tdoll,

    I have create a complete code example that showcases how to use the functionality of the getdisplayrows method.
    Code example:

    
    import * as React from 'react';
    import 'jqwidgets-scripts/jqwidgets/styles/jqx.base.css';
    import JqxGrid, { IGridProps, jqx } from 'jqwidgets-scripts/jqwidgets-react-tsx/jqxgrid';
    class App extends React.PureComponent<{}, IGridProps> {
    
        private myGrid = React.createRef<JqxGrid>()
    
        constructor(props: {}) {
            super(props);
            
            const source: any =
            {
                datafields: [
                    { name: 'CompanyName', type: 'string', map: '0' },
                    { name: 'ContactName', type: 'string', map: '1' },
                    { name: 'Title', type: 'string', map: '2' },
                    { name: 'Address', type: 'string', map: '3' },
                    { name: 'City', type: 'string', map: '4' },
                    { name: 'Country', type: 'string', map: '5' }

    Thanks for the example script! Below is an updated script using a FC and a hook. When the onFilter is triggered the recordNum is set, but the grid no longer functions properly (the filtering does not work) when the value is set. If you comment out setRecordNum, the grid works fine. I am using jqwidgets-scripts 12.0.0.

    import * as React from ‘react’;
    import { useState } from ‘react’;
    import { Card, Col, Container, Row } from ‘react-bootstrap’;
    import JqxGrid, { jqx } from ‘jqwidgets-scripts/jqwidgets-react-tsx/jqxgrid’;

    const Automation: React.FC<{}> = () => {

    const myGrid = React.createRef<JqxGrid>();

    const [recordNum, setRecordNum] = useState(0);

    const onFilter = (): void => {

    if (myGrid?.current != undefined && myGrid?.current != null) {
    console.log(myGrid!.current.getrows().length);
    console.log(myGrid!.current.getdisplayrows().length);

    setRecordNum(myGrid!.current.getrows().length);

    }

    }

    const source: any =
    {
    datafields: [
    { name: ‘CompanyName’, type: ‘string’, map: ‘0’ },
    { name: ‘ContactName’, type: ‘string’, map: ‘1’ },
    { name: ‘Title’, type: ‘string’, map: ‘2’ },
    { name: ‘Address’, type: ‘string’, map: ‘3’ },
    { name: ‘City’, type: ‘string’, map: ‘4’ },
    { name: ‘Country’, type: ‘string’, map: ‘5’ }
    ],

    { text: ‘City’, datafield: ‘City’, width: 100 },
    { text: ‘Country’, datafield: ‘Country’ }];

    let dataAdapter = new jqx.dataAdapter(source);

    return (

    <Card>

    );

    }

    export default Automation;

    Hi tdoll,

    I have tested the jqxGrid with the settings from your reply and this is definitely a bug/issue and I will add a work item for this case and we will work on to fixing it as soon as we are able to.

    I’m using the v12.1.2 of jQWidgets and the problem is really coming from the state hook, because it clears the filter of the jqxGrid and I also would like to thank you for your cooperation as it helps us improve our products constantly!

    Please, do not hesitate to contact us if you have any additional questions.
