Apply to Each (Loop) for ListBox items in Power App

Posted on by claytonsmithnz 4

Hi,

 

I'm in the process of building a power app that will Print labels via a REST API (Brother printer installed on Print Server).
I am able to print successfully when I statically set the fields for a single label (so printing/api is working).

 

I have a Listbox that displays a list Names (to be printed), I am not able to select multiple listitems (Names) and print the different names selected.

 

I have tried ForAll, it will print the right amount of labels selected, but prints the same persons name and details.

Any ideas how I could send a PRINT Api command for each selected item?

Thanks

Clayton

    @claytonsmithnz ,

    Inside the PRINT.POSTPRINT function you are referencing to UI controls, so it will only return you the selected Control values each time.

    You need to reference the Selected items by using ThisRecord.
