When the "star" is clicked - make it yellow

Posted on by stayclassy

Hello,

In my Power App, there is a "Star" icon (which doesn't have all the events like other icons). When I click on the Star, it should turn gold (the function is already provided - clicking adds the selected item to the Favorites list for the current user). Also, the user must be able to remove the selected item from the Favorites list by clicking on the "X," and the star should return to its colorless state. Thank you for your help!

Hi stayclassy,

You need a field in your Data Source (I will call it Favourite here) - Text is easiest, Then OnSelect of the Star icon (this allows unselecting as you have specified)
Patch( DataSource, ThisItem, { Favourite: If( ThisItem.Favourite = "Yes", "No", "Yes" ) } )

Then the Fill of the Icon (I am assuming it is currently White)
If( ThisItem.Favourite = "Yes", Color.Yellow, Color.White )

Please click Does this answer your question if my post helped you solve your issue. This will help others find it more readily. It also closes the item. If the content was useful in other ways, please consider giving it a Like.

HI,

You have posted in the Pro Dev & ISV so the expectation is your are a pro and stuck on something.

I am not sure if you are using a Canvas App or Model driven. You have provided no details at all about names of controls, or pictures of your app.

Are you trying to ask for help with the help or building a PACF Component? I am not sure at all.

Also, you should have an app with basic functionality and please post this in the Power Apps, Building Apps Section

Hi @stayclassy

I have been able to do this by creating two collections "Documents" and "User Favorites". Please see below.

Documents

ClearCollect( Documents, { Doc: "Doc1.docx", ID: 1 }, { Doc: "Doc2.docx", ID: 2 }, { Doc: "Doc3.docx", ID: 3 }, { Doc: "Doc4.docx", ID: 4 } );

User Favorites (Replace placeholder email addresses)

ClearCollect( User_Favorites, { Email: "----E-Mail Address---", Favorites: "1,2" }, { Email: "----E-Mail Address---", Favorites: "3,2" }, { Email: "----E-Mail Address---", Favorites: "1,3" }, { Email: "----E-Mail Address---", Favorites: "4,2" } );

Documents Gallery

Gallery Items: Documents (Collection)

Star Icon Fill

If( ThisItem.ID in Split( LookUp( User_Favorites, Email = User().Email ).Favorites, "," ), Color.Gold, Color.White )

Star Icon OnSelect (If user does not exist in collection, patch new record otherwise update the existing record)

Patch( User_Favorites, If( IsBlank( LookUp( User_Favorites, Email = User().Email ) ), Defaults(User_Favorites), LookUp( User_Favorites, Email = User().Email ) ), { Favorites: If( ThisItem.ID in Split( LookUp( User_Favorites, Email = User().Email ).Favorites, "," ), Concat( Filter( Gallery1.AllItems, Star1.Fill = Color.Gold && !(ID = ThisItem.ID) ), ID, "," ), Concatenate( Concat( Filter( Gallery1.AllItems, Star1.Fill = Color.Gold && !(ID = ThisItem.ID) ), ID, "," ), ",", ThisItem.ID ) ) } );

User Favorites Label (Just to see the favorites of current user)

LookUp(User_Favorites, Email = User().Email).Favorites
