Hi Joseph,
Thanks for contacting Syncfusion support.
Based on your query we can able to reproduce the mentioned issue at our end. In this we found that the issue occurs when combining the Aggregate, Resize and Freeze feature and by calling the autoFitColumns() method in the dataBound event.
We have validated the problem and we have considered “when combining Aggregate, Resize and Freeze and calling autoFitColumns() on the same Grid throws script error” as a defect and logged a report for the same. We will include the defect fix in our upcoming March 011, 2020 patch release.
You can now track the current status of your request, review the proposed resolution timeline, and contact us for any further inquiries through this link.
Regards,
Prasanna Kumar N.S.V
