Save & Load variable

[Anonymous]

Hi!  
I need my app to save a value (false) when it's offline. The app will close. Once opened again the app this value must be loaded and change the "visible" property of the buttons to "false". (visible = varGespeichert)

I save the variable using..

I initialize the variable so that, in case there are no saved data, the buttons are visible 

and to load the data and change the "visible" property I have used several formulas, for example:
      If(!IsBlank(VAsavedData); LoadData(VAsavedData; "isGespeichertFile"; true);;
      If(!IsBlank(VAsavedData); UpdateContext({varGespeichert: First(VAsavedData).varGespeichert});;

I can't get it to work. I would be very grateful for your help.

Hi @Anonymous ,

Do you want to save the global variable as a cached data within your PowerApps Mobile App?

Based on the formula that you mentioned, I think there is something wrong with it. I have made a test on my side, please take a try with the following workaround:

When your app is offline, save your global variable as cache data using following formula:

Set(varGespeichert; false);;
ClearCollect(
                    VAsavedData;
                    varGespeichert
);;
SaveData(VAsavedData; "isGespeichertFile")

When you load the cached data into your app, please take a try with the following formula (Set the OnVisible property of the first screen of your app to following😞

LoadData(VAsavedData; "isGespeichertFile"; true);;
Set(varGespeichert; First(VAsavedData).Value)

then you could use the global varGespeichert variable within your app.

Best regards,

Thank you very much for your answer @v-xida-msft!!

So I finally got it to work with the following code:

LoadData(VAsavedData; "isGespeichertFile"; true);;

If(!IsEmpty(VAsavedData) && !IsBlank(VAsavedData); Set(varGespeichert;First(VAsavedData).varGespeichert))

Best regards,
