I have a template that has a field in the sheet name. This field works fine when placed in one of the cells. However, when it’s placed in the sheet name, it gives an error indicating that it does not exist in the table.

Hello,
We do not face the issue at our end in applying the sheet binding. Please find the attached sample implementing the same and let us know if you are doing anything different.
If you still face any issues then please modify the attached sample accordingly to replicate your scenario.

If the field has no value, error. What should happen is to set a default value when the field is empty.

I send the following code and I send the template.
I’ve been running some tests and found that if I remove the reference to datasource p in the template, it doesn’t throw an error. If I keep the datasource p, it throws the error: System.ArgumentException: ‘The ‘CodEstado’ column doesn’t belong to the table.’

Hello Joao,
Apologies for the misunderstanding of the case.
>>If the field has no value, error. What should happen is to set a default value when the field is empty.
The Default value is used when a particular field is empty or missing from the data source. Please see the following attached sample demonstrating the same.
>>I send the following code and I send the template.
Thanks for the code but we do not see any template file attached. Please find the attached sample and modify it accordingly as per use-case so that we can assist you further.
Regards,
Prabhat Sharma.

Hello Joao,
>>I remove the reference to datasource p in the template, it doesn’t throw an error.
What do you mean by removing reference to data source p in the template? Are you doing some updation in the template Excel or in code?
>>If I keep the datasource p, it throws the error: System.ArgumentException: ‘The ‘CodEstado’ column doesn’t belong to the table.’
We did not face such an issue so we would request you to update the last given sample and template accordingly to replicate the same behavior so that we can assist you further accordingly.

If you open the template, you will see that it has two datasources p and d. If you run the code with the template, you get the error that the field placed in the name of the sheet is not found. Removing the datasource p does not give an error. The field that is on the sheet belongs to datasource d.
To simulate this error just create a model with two datasources. The first one (p) with a line of data to fill in the header and the second one for the detail (d). If you put a field of datasource d gives error. Removing the reference to datasource p from the excel model does not give an error.

Hello Joao,
>If you open the template, you will see that it has two data sources p and d.
We have checked this post and your support post but there is no such template file attached from your end and the template file that we have attached contains only a single data source.
However, based on your latest comments, we have replicated the issue at our end and reported this to the development team to look into this matter.
Please check the attached sample and confirm if you are having a similar use case.

Hello Joao,
As per the developers, we do not support such usage for multiple data sources. The template cell must be constrained by its sheet name if the sheet name is a template.
https://www.grapecity.com/documents-api-excel/docs/online/template-fields.html
Please see the attached screenshot for the same.
As a workaround, you need to merge two data sources into one and change the sheet name of the template file.

Thanks.
I got around the situation passing an object as datasource header.
