I found the solution to the Error: Cannot read property ‘val’ of undefined, you have to change this line:

nestedGrid.addEventHandler(‘rowclick’, function (event) {

for this:

nestedGrid.addEventHandler(‘rowclick’, (event) => {

Help, I want to load the value of city variable in jqxinput but it fails in

nestedGrid.addEventHandler(‘rowclick’, function (event) {
console.log(ordersbyid[event.args.rowindex].ShipCity );
this.city=ordersbyid[event.args.rowindex].ShipCity;
this.myInput.val(this.city)
});

thanks for you collaboration Toodor, see you later

[adrianBalonParticipant]

Thanks, exactly what you were looking for, adapt the code to obtain the data of a specific cell of the selected record

if (nestedGridContainer != null) {

let settings = {
theme: ‘material’,
width: 780,
height: 200,
source: nestedGridAdapter,
columns: [
{ text: ‘Ship Name’, datafield: ‘ShipName’, width: 200 },
{ text: ‘Ship Address’, datafield: ‘ShipAddress’, width: 200 },
{ text: ‘Ship City’, datafield: ‘ShipCity’, width: 150 },
{ text: ‘Ship Country’, datafield: ‘ShipCountry’, width: 150 },
{ text: ‘Shipped Date’, datafield: ‘ShippedDate’, width: 200 }
]
};

const nestedGrid = jqwidgets.createInstance(#${nestedGridContainer.id}, ‘jqxGrid’, settings);

nestedGrid.addEventHandler(‘rowclick’, function (event) {
console.log(ordersbyid[event.args.rowindex].ShipCity );
});
}
