In the app OnStart i have:

LoadData(Colitemtokeep, "Saveditemstokeep", true); If(!IsEmpty(Colitemtokeep), [Notify("You still have unsent Data. Remember to send then once you have an internet connection"), NotificationType.Error, 4000])

This pulls saved data into the collection and shows a warning if data was available that the user should have submitted this last go...

In the 'onvisible' i have:

If(!IsEmpty(Colitemtokeep), UpdateContext({popup: true}))

This does the same above but with a nice popup (visible).

If the user starts the app the onvisible dosn't work but if they go back to the home screen it works a treat 🙂

Any ideas how to get it to work on the first go?

I guess the Onvisible is on the Home screen. That is how Onvisible works. It works on whenever you go to that particular screen. If you want it work across many screens, use Set instead of Onvisible or replicate the Onvisible on that screen also.

Hi, i just want it to work on that screen.

It's fine when i return to that screen, i wonder if it's getting to homescreen before the data is loaded and visible?

No. The Data is loaded at the start of the app.
The Onvisible only check if there are records on what was loaded OnStart. Hope it's clear.

Instead of messing with a variable just set the visible of the pop up to be !isempty(collection) this should only show when it’s not empty and instantly go away when it is.

Well never mind. I’m assuming your wanting to be able to dismiss the pop up.

Sooo close!

I've trimmed the warning and IF and added !IsEmpty(Colitemtokeep) to the visible (that hadn't even occurred to me!)

New issue:-

The popup has 2 buttons, I've fix this later and let's fix this now..

The 'fix this later' button updated the context of visible to false and the popup went. How do i do that now?

You can’t without a variable. Instead of update context try to do a set like suggested. So If(!isempty(col),set(show popup,true))

If that doesn’t work. Add the same line of code to your on start.

Ok

App
Onstart: LoadData(Colitemtokeep, "Saveditemstokeep", true); If(!IsEmpty(Colitemtokeep),Set(popup,true))

Homescreen
Onvisible: If(!IsEmpty(Colitemtokeep),Set(popup,true))

Popup group
Visible: popup

Popup button
Onselect: Set(popup,false)

Still no luck

So the popup isn't coming up on start? Until you nav off? I know there is a preview feature in the app settings for loading controls before data, not sure that's on by default or the cause but something to look for possibly.

Also, I can't remember if isBlank() would work better or if it works on a collection at all, but it might be an alternitive.
