Hi all,

I am working on a navigation app. On a tab screen, the user can select a route. Each route can be travelled in 2 directions. I’d like to populate 2 buttons on the screen based on the route selected. Some go N-S, some go E-W, etc. It will allow the user to indicate which way their traversing the route.

all help appreciated

JJ

Sounds like you want either a choice component/action row/button block that writes to a user specific column, then use the value written in whatever table logic is required.

When does the data get written? If the choices are in a form, it’s on submit. If not in a form, when does the data get written?

I’d been struggling because the value I need to lookup isn’t in the table until after submit.

Yes, when using a form the values aren’t written until after submit.

But based on your earlier description, should you be actually using a form? A form will add a new row - is that what you want?

Perhaps I’m not understanding your goal. A screen shot or two might help provide a better visual.

So are non-form components committed or written when they’re filled out?

Yes, if you are not in a native form, then changes are updated almost instantly in the table as soon as you change the value.
