Hi,

I have an interface with a selection grid in which multiple rows can be selected, these selected rows are saved into a ri of the CDT type. I have the requirement of capturing and storing all the unselected rows (the rows which were not selected) into a ri.

Any ways to do this?

TIA!!

The difference() function should help here. It can not only take strings or numbers, but CDTs as well. Give it a try

docs.appian.com/.../fnc_set_difference.html

Maybe you can use difference(array1,array2), where array1 is all the rows, array2 is selected rows.
difference gives unselected rows

Thank you for your replies. I had tried difference() earlier but there was an error because the type of both arrays were different.

I tried using remove() using the original array and the selected indices and was able to get the unselected rows.

If the types do not match, the cast() function should help. To cast to a list, just add "?list" to the CDT type. There is no need to do

typeof({type!YOUR_CDT_TYPE()})

thanks for the awesome information.
