Add current row name field to an element using existing properties dialog

I selected ( green arrow )
from the existing properties dialog ( red arrow )
when it was showing “selected row” item in the dialog

now trying to drag to the text area…
and the “selected row” option is not available

what do I have to do to get it back?

does this have anything to do with it?

There must be a bug. How are you using the component? Is it a list item component or just a single component element in a screen?

This is a component used by a list

  List/Grid  (take item values from Data Sheet; that has 1 row)
       This component (text, textbox, save-button)

Is this the recommended way to edit a single row of a table?
