saveData() not storing image files locally for offline use

Hi,

 

New to PowerApps development. 

 

I have an app that connects to a SQL Azzure DB.  The idea is that I want to connect to the DB once, cache the data and be able to use the app with all the data from the DB while offline.  I use SaveData() and LoadData() to do this.  Once cached and I go offline my app seems to store and access varChars(), Dates, etc correctly.  However, the images (saved as varBinary(MAX)), never show up in the app when offline.  

 

Thank you in advance for any help

Hi @samuelJ,

 

Can you share your formula that set for the offline mode app?

@v-monli-msft

 

Please find below the code I am using, it is in the OnStart of my app.  I do want to emphasize this seems to be working for Varchars, Date & Times.  Once I initially load the data, I go offline and see all that data, just not the pictures, which are VarBinary(MAX).

 

If(Connection.Connected, 
//if it is connected clearCollect the collections and save the data locally
ClearCollect(collectionOne, Filter('[dbo].[collectionOne]', conferenceId = varconferenceID));
ClearCollect(collectionTwo, Filter('[dbo].[collectionTwo]', conferenceId = varconferenceID, isDisabled = false ));
ClearCollect(collectionThree, Filter('[dbo].[collectionThree]', conferenceId = varconferenceID, isDisabled = false ));
ClearCollect(collectionFour, Filter('[dbo].[collectionFour]', conferenceId = varconferenceID, isDisabled = false));
ClearCollect(collectionFive, Filter('[dbo].[collectionFive]', conferenceId = varconferenceID, isDisabled = false));
ClearCollect(collectionSix, Filter('[dbo].[collectionSix]', conferenceId = varconferenceID, isDisabled = false));
ClearCollect(collectionSeven, Filter('[dbo].[collectionSeven]', conferenceId = varconferenceID));
ClearCollect(collectionEight, Filter('[dbo].[collectionEight]', conferenceId = varconferenceID));
ClearCollect(collectionNine, Filter('[dbo].[collectionNine]', conferenceId = varconferenceID));

SaveData(collectionOne, "collectionOne");
SaveData(collectionTwo, "collectionTwo");
SaveData(collectionThree, "collectionThree");
SaveData(collectionFour, "collectionFour");
SaveData(collectionFive, "collectionFive");
SaveData(collectionSix, "collectionSix");
SaveData(collectionSeven, "collectionSeven");
SaveData(collectionEight, "collectionEight"),

//if the app is not connected, load what ever data is stored locally in the app

Clear(collectionOne);
Clear(collectionTwo);
Clear(collectionThree);
Clear(collectionFour);
Clear(collectionFive);
Clear(collectionSix);
Clear(collectionSeven);
Clear(collectionEight);

LoadData(collectionOne, "collectionOne", true);
LoadData(collectionTwo, "collectionTwo", true);
LoadData(collectionThree, "collectionThree", true);
LoadData(collectionFour, "collectionFour", true);
LoadData(collectionFive, "collectionFive", true);
LoadData(collectionSix, "collectionSix", true);
LoadData(collectionSeven, "collectionSeven", true);
LoadData(collectionEight, "collectionEight", true));
