Hello @Paulo Torres
Could you please provide some additional information to allow us to try to help you:
- Data Grid version
- Sample module with the use case you mentioned, so that we can try to replicate
In order to have more control and customizations on the columns, you need to add them one by one since columns are OutSystems blocks like the ones you can do on any project. You can also have auto-generated columns but in that case, you'll lose several functionalities, so we truly advise using the blocks.
Best Regards,
GM
