Highlight new items in gallery depending on last login of user - show new item icon

Hi Community,

I'm looking for some bright minds to solve the following problem.

I´m looking for a soluction to check if new items where uploaded to the app since last user login to highlight them. After next login the "highlight" icon, for example "new" should be invisible for this user.

What is the starting point:

I have created the follwoing formula for the OnStart field of the App:

Set(lookupRecord; LookUp('App Logins'; Title = User().Email));; If(IsBlank(lookupRecord.Title); Patch('App Logins'; {Title: User().Email});Patch('App Logins';First(Filter('App Logins'; Title = User().Email)); {'Last Login': Now()}))

App Logins is a separated sharepoint list which is connected to the App and stores the logged in users without producing duplicates. When the user opens the app for the first time, then it is saved in the list. If the user already exist in the list, the "Last Login" field will be updated with the actual date and time.

In my gallery i have inserted a icon with the following "visible" code:

If(LookUp('App Logins'; Title = User().Email).'Last Login' >= ThisItem.Modified;false;true)

So far so good. My problem is that the icon is only visible for a short time (time between the update of the "Last Login" field which automatially changes the Modified field in this list.

That´s why I´m looking for ideas to solve the problem. One solution could be, to wait with the patch function for the App logins until user leaves the App.

Do you have an idea how to?

Hi @PowerApp14,

You will have to temporarily save the previous login record state before updating it in the OnStart. This is something you are actually already doing. This variable can then be referenced within your Visible code. I made some adjustments to your OnStart code and added inline comments to further explain the changes.

Set( //Renamed variable - here we save the last login record if it exists gblLastLogin; LookUp('App Logins'; Title = User().Email) );; If( IsBlank(gblLastLogin.Title); Patch( 'App Logins'; //Added Defaults Defaults('App Logins'); { Title: User().Email } ); Patch( 'App Logins'; //Use variable as record reference instead of First Filter gblLastLogin; {'Last Login': Now()} ) )

Your Visible property will look as follows:

//Only display when the user logs in for the first time or hasn't logged in since the record was modified IsBlank(gblLastLogin.'Last Login') || gblLastLogin.'Last Login' < ThisItem.Modified

If this solves your question, would you be so kind as to accept it as a solution & give it a thumbs up.

Thanks!
