Selecting data master record literally, or data grid Row_1 syntax
I have a data master with a few records (ex: Countries: US, Canada). I want to call the "edit" screen for a record (Canada) but instead of doing so from a row in a data grid, I want to do it from a literal link (because I'm faking a 2-level grid). I got a workaround working by first making a hidden data grid; then filtering it to the desired record; then passing "Row_n" to a variable, like the boilerplate 'Generate>Data Grid' page. Isn't there a cleaner way of 'selecting' and passing a record? It looks like I need to know the syntax of what is sent in for example 'Row_1" in some tutorials... or some Filter/Select syntax that I'm not guessing right at.
