Hi Zhaojian,
Thank you very much for using Syncfusion products.
In your previous post we could see you are using the UltraGrid Control to export in in to the excel document. We have tried to download the prodcut at our side and we are unable use it at our side. We could not find the download link for the same.
So we have created the XlsIO sample at our side for the above requirement and updated here for your reference. We are using 9.3.0.61 version and let us know the essential studio version you are using at your side.
Please try the sample at your side and let us know if these helps you. If you still face the issue, Please get back to us with the sample to proceed further.
Please let us know if you require any further clarifications.
Thanks,
Sridhar.S
