Hi @MAYLIWK ,
Do you want to set person combo box's defaultselecteditems by using the data of a collection?
Could you tell me the data in the collection in details?
You could use this formula to set person combo box's defaultselecteditems:
DefaultSelectedItems for the combo box control, you can use this expression:
Table({
DisplayName:User().FullName,
Claims: "i:0#.f|membership|" & User().Email
})
For example,if your collection has the data of Email and full name, you could try:
Table({
DisplayName:First(collection).fullname,
Claims: "i:0#.f|membership|" & First(collection).Email
})
About updating, you could set this person data card's Update:
Combo box.SelectedItems
Best regards,
