save user settings

[Anonymous]

You will see I have a tablet application in which I have 2 icons:

one of a moon

(dark mode)

one of a sun
(Clear mode)

I want to save the user configuration since the light mode will be by default but if you choose the dark mode I want that when you re-enter the application continue with the dark mode.

It would be great to be able to do it with a formula that I have read from the SaveData formula, but it doesn't work when I apply it maybe I don't apply it well.

If the solution is in a Sharepoint list, I prefer not to apply this.

Create a Table OnStart of Your App (You can also use your Existing Table):

Set( UserTable7,

Table({ EmailAddress: "sss@aa.com", Name: "RR", PreferedColor: "ColorBlack"},

{ EmailAddress: "kss@aa.com", Name: "PP", PreferedColor: "ColorBlue" },

{EmailAddress: "uu@aa.com", Name: "LL7", PreferedColor: "ColorWhite"}

))

Then do a Variable OnVisible or Also OnStart of the App to lookup the User

prefered Color:in:

Set(VarMyColor,LookUp(UserTable7,EmailAddress=User().Email,PreferedColor))

Finally, in the Fill of the Form or Screen put:
VarMyColor

My method will save the DarkMode settings to the device.

Put this code in the OnSelect property of your Moon icon 

ClearCollect(colUserSettings, {DarkMode: true});
SaveData(colUserSettings, "UserSettings");

Then, put this code in the OnSelect property of your Sun icon.

ClearCollect(colUserSettings, {DarkMode: false});
SaveData(colUserSettings, "UserSettings");

Finally, use this code in the app OnStart property.

LoadData(colUserSettings, "UserSettings");
Set(isDarkMode, LookUp(colUserSettings, First(colUserSettings).DarkMode);

Now you can check for DarkMode at any time by using the variable

isDarkMode

hi @mdevaney 

it gives me the following error telling me that it cannot save data in the web browser

You can't save data in a web-browser.  SaveData and LoadData only work on a mobile device like a tablet.  I assumed this was OK because your question said you were making a tablet app.

There is no work-around for a PC/Laptop.  You must save this info to a datasource like SharePoint.

I followed you entire solution, but it didn't work. Don't have a clue why.

On the web interface I got errors saying that "Name isn't valid. This identifier isn't recognized".

Perhaps it's because the web interface can't save files (know this), so it can't run the app, and thus - don't recognize the variables?

And perhaps I'm not checking isDarkMode correctly, either of these work:

If( isDarkMode:True, "Darkmode!", "WhiteMode")

If( isDarkMode=True, "Darkmode!", "WhiteMode")

If( isDarkMode = "True", "Darkmode!", "WhiteMode")

BTW, I'm trying to save user's preferences about language and interface.

Stumble upon this old post, great solution @mdevaney 

Can use this example if i have multiple toogles?
Lets say i have one for Dark Mode and one for Compact mode.
I cannot use clearcollect as it will erase the other setting, i tried to use patch to update the table but not successfully.

I have two toggle switches as i described how do i update the collection value when i toggle?

[JimmyWork]

Did it like this:

Set(var3, true);
ClearCollect(colUserSettings,
{TicketID: var1},
{DarkMode: var2},
{CompactMode: var3}
);
SaveData(colUserSettings, "UserSettings");
