Hi Rajiv,
Thank you for contacting Syncfusion support.
We were unable to reproduce the reported issue “Export is not working” at our end and for the same we have prepared a sample with the provided code example for your reference.
Kindly try the above sample and if the issue persists, try to reproduce the error in a sample and revert it back to us. Or else you can share a video demo/code example/sample (if possible) to proceed further.
Regards,
