I would make a custom sharepoint form for a library that has a lookup column with additional fields.
I would like the powerapps form to display the values of the additional fields as soon as the main field is selected.
I do not find how to solve this problem.
I need a help.
Hi @StephaneVedren ,
Sorry but I think you might need to provide more details about your issue for further analysis.
By "a lookup column with additional fields", did you mean that you have created a lookup column for Library and have checked some additional fields in below checkboxes?
If so, then just add both data cards to the Form control:
You could see that only Lookup field can be edited. In edit mode, after you select the value for Lookup field, it's true that the value won't show for additional field. But once you click on save button, additional fields would be updated automantically with the corresponding value:
This is the expected behavior, and I think you cannot change it from PowerApps side. This is because even in SharePoint list Quick edit mode, after you selecting the value for Lookup field, additional fields would be empty until you Exist quick edit.
