Dropdown on edit form not showing text from detail screen

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.

Did you try Default property of the Dropdown, and simply setting this property to TextField.Text?


yes. No error, but it's still blank. I have the items property set to LookUp('Alarm locations',Building=DataCardValue4.Text, Facility)

however, i get an error that says expected table value.



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) )


It doesn't work. Error message is 'Cannot use a non record value in this context.'

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
