Hi Arbor,

Greetings from Syncfusion.

We suggest you to use `rowDataBound` event to achieve this requirement, please refer the below code snippets and sample.

[app.component.ts]

public rowDB(args){

if(args.data.EmployeeID < 6){

args.row.querySelector('tr').classList.add('bgcolor');

}

[app.component.html]

<ejs-grid #grid [dataSource]='data' (rowDataBound)='rowDB($event)' height=335 width='auto'>

Sample: https://stackblitz.com/edit/angular-9tucrb?file=app.component.ts

Regards,
Hariharan

sorry maybe my question was not very clear.

I want to set background color upon row click not pre-selected row. I should have used active-row instead of selected.

Can you provide me a solution to achieve this?

Thank you,

Hi Arbor,

From your query, we found that you want to change the row background color while clicking the particular row. You can achieve this requirement like as following way,

rowTemplate:

<ng-template # rowTemplate let-data>

...

</tr>

</ng-template>

Click event:

ngOnInit(): void {

this.grid.element.addEventListener('click', function(e){

let element = e.target;

let row = parentsUntil((element as Element), 'parenttr');

if(!isNullOrUndefined(row)) {

let prevSelectedRows = gridInstance.getContent().querySelectorAll('.bgcolor');

for( let i = 0; i < prevSelectedRows.length; i++){

prevSelectedRows[i].classList.remove('bgcolor');

}

row.classList.add('bgcolor');

}

})

}

We have modified our sample with this requirement and you can find that modified sample in the below link,

Sample: https://stackblitz.com/edit/angular-9tucrb-hp2zvs?file=app.component.ts

In this sample, we have added “parenttr” class to all the Grid rows. So we can easily find the Grid row while clicking any row template elements by using this class with Grid parentsUntil method.

Regards,

Hariharan
