Hi Parth,
Greetings from Syncfusion support.
Query: setCellValue not working when column is Frozen
We have validated your query and we are able to reproduce the same problem at our end. So, we have considered this as a feature improvement and logged a feature improvement task “SetCellValue does not work when column.isFrozen Property is set to true” for this requirement. We have planned to include this feature improvement in any of our upcoming releases. We appreciate your patience until then.
You can now track the status of your request, review the proposed resolution timeline, and contact us for any further inquiries through this link.
