Remote data, Expanded rows doesnt appear under corrent parent

[Mindaugas Ežerskas]

Hello,

After clicking expand button, childs are not added to correct parent

while debugging found out that in ej2-treegrid.es5.js, "currentViewData" is correctly before sort on ::2600.

Or this https://www.npmjs.com/package/@syncfusion/ej2-treegrid line ::568 @syncfusion/ej2-treegrid / src / treegrid / base / data.js.

After sort happens it ruins how rows are displayed

Versions we use:

"@angular/core": "^19.2.0"

"@syncfusion/ej2-angular-treegrid": "^30.2.4",

This is demo of how data looked before and after sort happens https://stackblitz.com/edit/angular-8ma4dvpo?file=src%2Fapp.component.ts,src%2Fapp.component.html

Best regards

Hi Mindaugas,

We appreciate your patience and understanding.

We have fixed the bug “Appending children is not working correctly below parent in ej2 remote data treegrid component.” and the fix has been rolled out in our latest weekly release (v 31.1.22). So, upgrade to our latest version to resolve the problem.

Root cause for the issue:

On expanding, the records get sorted before appending. Due to sorting the records based on the idMapping, the child records were sorted and moved to last indexes.

Package : https://www.npmjs.com/package/@syncfusion/ej2-react-treegrid

Sample: https://stackblitz.com/edit/react-w7s75vr5-qzgh8uha?file=package.json,index.js

Please get back to us if you need any further assistance.

Regards,

Shek
