Retain Exit Settings for Next OnStart

[Phineas]

I have a main screen that has a series of buttons that allow for users to navigate through the app.

I have a toggle (Toggle1). I use the toggle to shutdown access to the site through the buttons referenced above.

The default setting of Toggle1 is 'true'. If for some reason the owner wants to limit access to the site for a period of time the owner can set Toggle1 to 'true' and all of the site buttons will default to 'Disabled'.

My issue, if the owner sets Toggle1 to off and then exits the site, when the owner returns the Toggle has reset to 'false' and all the button are back to 'Edit'.

How do I set it up so that the setting of Toggle1 is how the site open during the next viewing?

I didn't mean to confuse things.

I have visual concept clarity issues.

It takes my time to see some things.

The table I referenced was created in a flow, for another pupose - you are correct I apologize.

Set(varVisible, LookUp(UserSettings, AppUserName = User().Email).varVisible);
Set(dispToggle, LookUp(UserSettings, AppUserName = User().Email).dispToggle);
Set(defaultLocation, LookUp(UserSettings, AppUserName = User().Email).defaultLocation);

Merely placing the above n the OnStart is going to force Toggle1 to default to the closed position when the app was last saved, yes? There is nothing else I need to do?

I've made a few edits to match my fields. Should the below deliver the outcome I desire?

Set(varVisible, LookUp(UserSettings, AppUserName = User().FullName).varVisible);

Set(Toggle1, LookUp(UserSettings, AppUserName = User().FullName).Toggle1);

Set(defaultLocation, LookUp(UserSettings, AppUserName = User().FullName).defaultLocation)

The code I posted above will read three values from a list called UserSettings (that already exists and has data in it) and put those into three variables I use in that particular app. Copying the code and changing the names to match some of your control names is only part of making it work. Do you also have a list called UserSettings connected to your app and does it have the exact same columns as my list? If not, you'll need to adjust this code further.

The other part is, and you recognized this in an earlier post, any changed variable data needs to get saved back to the list if you want to use it in the future. You correctly recognized that the Patch() function works for this. If there is no data for the LookUp() function to read in the first place, the app won't set proper values to the variables.

Ok, I've changed the condition to include only fields/columns in my lists.

Set(varVisible, LookUp(ComplianceList, FullName = User().FullName).varVisible); 

     - This looks for the default setting on the list, yes?

Set(Toggle1, LookUp(ComplianceList, FullName = User().FullName).Toggle1);

     - This sets the default setting of Toggle1 based on the content of the field at OnStart, yes?

Set(defaultLocation, LookUp(ComplianceList, FullName = User().FullName).defaultLocation)

     - What does this do?

Consequently, how should the Patch look, where should I place the Patch command for Toggle1 (I know there is a difference between OnCheck, OnUncheck, OnChange)  go, and where is the Patch sending the information?

I don't have a Patch and I don't have a list or table that is currently collecting the default status of Toggle1.

Patch(...

I'll describe what Set(varVisible, LookUp(ComplianceList, FullName = User().FullName).varVisible) does to help you understand what's going on here: This lookup searches for the first record in ComplianceList that the current user's name matches a value in the FullName column. When this lookup finds that first match, it will return the value stored in the varVisible field of that same record. Set() will point the global variable varVisible to this return value from the lookup.

Your app may not need all of these lookups - they are simply ones I used in one of my apps. dispToggle and defaultLocation are additional columns & variables I used in my app and your app may not require these.

To Patch() a value back to the list (in a behavior formula, usually right after the variable was changed by Set), use code like this:

Patch(ComplianceList,
    LookUp(ComplianceList, FullName = User().FullName),
    {
    varVisible: varVisible
    }
)

Okay, its starting make a little sense. 😂

So, I need to create a List that has a column that stores the default/Patch setting of Toggle1, yes?

I should place the Patch command in the 'OnChange' property of Toggle1, yes?

I should place a condition in the 'OnStart' of the app, yes? The list I will create for this won't have anyone name in it to match. Whatelse should/can I use in the condition. The list will have one row with one column 'ToggleStatus', set to default in SharePoint to 'true', with the Patch changing it back and forth between 'true/false'.

     Set(Toggle1, LookUp(ComplianceList, FullName = User().FullName).Toggle1);

Yes, that's correct.

Yes, that would be a good place to put it.

You have a couple of choices here:

1. You can pre-populate your list with values, or
2. You can modify your OnStart code to check to see if a LookUp for that user returns a valid value, and if not you set the variable to a preselected default value

[Phineas]

Right now the Toggle1 default property is 'true'.

How do I write the Lookup in the 'OnStart' to make it pull in the current content of the column in the List? The only column in the List is 'SiteStatus', with the content of 'true' (by default).

     Set(Toggle1Default, Lookup('Site Start Up List',...)

I'm not quite sure I understand where you are going with this question: You should ensure all necessary columns are present in your list and make sure there are values present (or your app knows how to handle the case with no values). A LookUp will return blank if it finds no matching record.

If you want to pull any value from this list, one way is with First():

First('Site Startup List').SiteStatus

This pulls up the value in the SiteStatus column from the first record in the list.
