I have an app where there is a text field on the detailscreen. I want it to be a dropdown on the editform. However, I can't get the dropdown to default to the content of the text field on the detailscreen.
LookUp('Alarm locations',Building=DataCardValue4.Text, Facility)
LookUp returns a Record, when Items expects Table.
Try this instead to quickly check it and see if this version works:
Table( LookUp('Alarm locations',Building=DataCardValue4.Text, Facility) )
If you want the dropdown to replace the Text box and only has one option which is the default text.
please try to set Items property of dropdown control as below:
Except that, you need to modify the Update property of data card: Dropdown1.Selected.Value, and Y property of ErrorMessage: Dropdown1.Y + Dropdown1.Height
