How can i prevent checkboxes from resetting when shutting down the app?

Question

Hi, i'm trying to make an app for a coin database.
Below a photo of the coin i put a checkbox or a switch to indicate what i have.
When closing and reopening the app, all the checkboxes or switches are unchecked.
Is there any way to let the app remember what was checked or unchecked.
Thnx.

Answer 1

Are you using a gallery to display your coins?  If so, this is what you'll need to do:
Part 1
1. Use a Collect function when the Checkbox is checked (and a RemoveIf function when the checkbox is unchecked.)
2. SaveData function to save the data.  This can be done when the checkbox is checked.  Use a semi-colon to string functions together.
Example (in the OnChecked):
Collect (myCoins, {ID: CountRows(myCoins) +1, CoinName: txtMyCoin!Text, IsChecked: "true"}); SaveData(myCoins, "MyCoins")
--> This code may not be 100% correct as I'm not on a computer with Siena while I'm writing this but it should be enough to get you started I hope.
Part 2
1. Use the LoadData function when you need the information to be loaded - usually in the OnVisible of a page.
2. In the Default of the checkbox (in your Gallery) add this code: If(ThisItem!IsChecked = "true", true)
--> Again, I'm not in front of my computer with Siena so I may be off here.  I'll edit this post if I'm way off.
I hope this gives you a good start.  I can provide better examples if this isn't working for you.
FYI - The code will look different if you're not using a gallery.  Hopefully you are as it sounds like the way to go in what you have in your example.
