Code :
Step 1: Here we will create an Apex Class for fetching account records. Create an Auraenabled static method that is invoked from the LWC component.
DataController.cls :
public with sharing class DataController {
@AuraEnabled (cacheable=true)
public static List<Account> retrieveAccounts(){
return [SELECT Id, Name, Type, BillingCountry
FROM Account
LIMIT 2000];
}
}
Step 2: in this step, We will create an LWC component in which we create Lightning Datatable with checkboxes.
SelectedRowsLWC.Html :
<template>
<lightning-Card title="Account List" icon-name="standard:account">
<lightning-button variant="Neutral"
label="Selected Records"
title="Selected Records"
onclick={getSelectedRec}
slot="actions"
icon-name="utility:check">
</lightning-button>
<div style="border-top: 1px solid rgb(221 219 218);">
<!-- datatable -->
<lightning-datatable
key-field="id"
data={data}
columns={columns}
column-widths-mode="fixed">
</lightning-datatable>
<!-- /datatable -->
</div>
</lightning-Card>
</template>
SelectedRowsLWC.Js :
import { LightningElement, track, wire } from 'lwc';
import retrieveAccounts from '@salesforce/apex/DataController.retrieveAccounts';
const columns = [
{ label: 'Name', fieldName: 'Name' },
{ label: 'Type', fieldName: 'Type' },
{ label: 'BillingCountry', fieldName: 'BillingCountry'},
];
export default class SelectedRowsLWC extends LightningElement {
@track data;
@track columns = columns;
@track error;
@wire(retrieveAccounts)
wiredAccounts({ error, data }) {
if (data) {
this.data = data;
this.error = undefined;
} else if (error) {
this.error = error;
this.data = undefined;
}
}
getSelectedRec() {
var selectedRecords = this.template.querySelector("lightning-datatable").getSelectedRows();
if(selectedRecords.length > 0){
console.log('selectedRecords are ', selectedRecords);
let ids = '';
selectedRecords.forEach(currentItem => {
ids = ids + ',' + currentItem.Id;
});
this.selectedIds = ids.replace(/^,/, '');
this.lstSelectedRecords = selectedRecords;
alert(this.selectedIds);
}
}
}
