Grid multi-select, initialize with multiple selected

[KEVIN KELLY]

I'm trying to use the enableSimpleMultiRowSelection of the GridComponent, and want to select rows initially for my component when it renders. 

There is a selectedRowIndex which only selects 1 row according to the docs. How do I select multiple, do I have to use the underlying Javascript functionality with a databound callback?

Hi KEVIN, 

Greetings from Syncfusion support. 

Based on your query we suspect that you want to select multiple record in Grid when load the Grid initially. So, we suggest you to use the below code example to achieve your requirement. 

[index.js] 

import { render } from 'react-dom'; 

import './index.css'; 

import * as React from 'react'; 

import { GridComponent, Grid, ColumnsDirective, ColumnDirective, Toolbar, ColumnChooser, Inject, Page  } from '@syncfusion/ej2-react-grids'; 

import { data } from './data'; 

import { SampleBase } from './sample-base'; 

export class ColChooser extends SampleBase { 

 

    dataBound(){ 

      this.selectedRowIndices = [1,2,4]; 

      this.gridInstance.selectRows(this.selectedRowIndices); 

    } 

    constructor() { 

        super(...arguments); 

 

        this.settings = { mode: 'Row', type: 'Multiple'}; 

     

 

    } 

 

    render() { 

        return (<div className='control-pane'> 

    <div className='control-section'> 

        <GridComponent dataSource={data} ref={grid => 

            this.gridInstance = grid} dataBound={this.dataBound.bind(this)}  allowPaging={true} selectionSettings={this.settings} > 

            <ColumnsDirective> 

 

                  ----- 

 

            </ColumnsDirective> 

            <Inject services={[Page]} /> 

        </GridComponent> 

    </div> 

</div>); 

    } 

} 

  

We have prepared a simple sample in the following stackblitz link.
