I have a editable grid with 3 columns: a id, question, grade. I need the id col

You can hide this column. When a user selects a certain row, it should save that row's identifier (set this to your id) into the variable supplied in the selectionSaveInto attribute. forum.appian.com/.../SAIL_Components.html

Thanks guys. Jackm829 the issue here is that a user is not selecting a row per se but answering a question via selecting a grade from a dropdown field.

If your use case is you have value in id and question column and user select grade from dropdown so for which row user selected grade you want to save id of that particular row then you don't have to show id to users, you can use this code in saveInto of dropdown field.

a!save(ri!SelectedIds,tointeger(index(index(local!Items,where(not(apply(isnull(_),local!Items.grade))),{}),"id",{})))

here SelectedIds is the variable of type list of number(integer) where you want to save selected ids.
Items is the type of cdt where you have these three columns.

Hi
You can save this id using another field which is required like grade.

you have to use this code into the saveInto parameter of grade dropdown

In apply Components:
saveInto:{
a!save(ri!selectedIds[ri!index],ri!item[ri!index].id)
}

In foreach loop
saveInto:{
a!save(ri!selectedIds[fv!index],ri!item[fv!index].id)
}

Where ri!items is complete which have 3 fields id, question and grade
ri!index is the index of row for editable grid
ri!selectedId is the field in which we want to store id.

Thanks
