Hi Goutham,
Greetings from Syncfusion support.
We have validated your reported behavior at our end and would like to inform you that currently the EJ2 Grid does not have support for checkbox selection with virtualization and grouping features. However we have already logged a feature task “Provide support to perform checkbox selection in virtualization with Grouping feature” for this and added it to our feature request database. We do not have any immediate plans to implement these features and we will implement this support in any of our upcoming releases. We usually have an interval of at least three months between releases, at the planning stage for every release cycle, we review all open features. We will let you know when this feature is implemented.
You can track the current status of this request, review the proposed resolution timeline, and contact us for any further inquiries through the below feedback link,
Let us know if you have any concerns.
Regards,
Sujith R
