Offline Apps best practice Canvas or Form?

Hi,

 

Ive started a new project to build some apps and previously i used the collect function with a canvas background and text inputs and choice fields to send to sharepoint, however ive started using the forms and using the datacardvalues as the inputs?

 

Does it make any difference?

 

I.e do the users need to initially pull the data from the choice fields columns in sharepoint etc rather than the canvas dropdowns being preselected etc?

 

hope i make sense

HI @Anonymous ,

Could you please share a bit more about your scenario?

Do you want to create a Offline canvas app based on your SP List data source?

Further, do you use the DataCardValues within the Edit form as Inputs rather than use the standalone Text Input box, Dropdown control, ... etc?

 

Based on the needs that you mentioned, I think using standalone Text Input box, Dropdown box, ... etc as Inputs and using DataCardValues within a Edit form as Inputs do not make any difference.

If you want to create an Offline app using SaveData() function and LoadData() function, you must firstly initialize a Collection to store the data you want to cache in your app.

Regardless of whether you use standalone Text Input box, Dropdown boxes, ... etc as Inputs or use DataCardValues in a Edit form as Inputs, you need to save the data into a Collection firstly. Then use SaveData() function to store the collection into your local device. When you re-load your app, use the LoadData() function to load the cache data into the same name Collection.

 

In terms of svaing data into a Collection, using standalone Text Input box, Dropdown box, ... etc as Inputs and using DataCardValues within a Edit form as Inputs do not make any difference.

Previously to make the apps offline i used a canvas and prefilled all the choice columns etc, and used collect and a timer i.e 

If(Connection.Connected
	,Patch('Grader Log',
		Defaults('Grader Log'),
		{
            Asset: Can_Assetid.SelectedText,
            Department: Can_Department.SelectedText,

		}
	)
	,Collect(GRADERCOLLECTION,
		{
			Asset: Can_Assetid.SelectedText,
            Department: Can_Department.SelectedText,

		}
	)
);
UpdateContext({ResetVar: true}); 
UpdateContext({ResetVar:false});
Navigate(BrowseGallery1, ScreenTransition.None)

and a on timer end

 

If(Connection.Connected,
    ForAll(GRADERCOLLECTION,
        Patch('Grader Log',
            Defaults('Grader Log'),
            {
             Asset: Asset,
            Department: Department

           }

        )

    );
    Clear(GRADERCOLLECTION)
)

And i would have an editform and a browsegallery to edit old entries if they needed to change an entry (works great)

 

I did it this way as it was the only way i knew how (plus ALOT of help from people such as yourselves, TY) However i now know you can just use the datacards the same way as textinputs and dropdowns, 

 

Im fine with creating a canvas offline app, im just experimenting with using the DataCardValues within an editform (its a time saver when you create the apps and some of my choice columns are large)

 

 

 

 

 

Personal preference, but I don't use Forms. Takes a little longer to create Apps but I prefer the flexibility of using my own controls and Patch/Collect for writing data.

Similarly I avoid using SharePoint choice fields unless strictly necessary (i.e. data will be input directly in the SharePoint list as well as via PowerApps). For any App where the backend requires performance, capacity or security, I use Azure SQL DB.
