I have a field that shows task owner(s) and am trying to represent these within my Gallery. It works when I only have one task owner (Rob) but when I have two (Rob & Eric) then I can't figure out how to show it. Any ideas?
Normal process: ThisItem.Owner
Process with dropdown: ThisItem.Owner.Value
Process with multi-select: ???
Expected output: Rob, Eric
The controls will give you back a table of selected values, and then you want to use the Concat() function to convert a table column into a string.
Say you control is a list box. You can collect the values
Concat(ListBox1.SelectedItems, Value & ";")
If it's a gallery, it will be like:
Concat(Gallery2.AllItems, ThisRecord.Subtitle2.Text & ";")
