Hey,

I'm new to PowerApps and am trying a few different things. and currently I'm trying to fill a gallery with items from SharePoint. The SharePoint List is quite short and simple, it has 3 titles and 3 screen names. What I want to do is that I'd like to set the gallery buttons OnClick = Navigate(ThisItem.Screen), except that ThisItem.Screen is a text, and not an object to navigate to. What I wonder about is if it's at all possible to find the screen whos Screen.name = ThisItem.Screen

This is probably not the best way to navigate to a new screen based on SharePoint information

Hi @Mats_1997 !

One way to solve this is to have a collection where you map the Screen name (text) in SP to the screen objects in Power apps. Like:
ClearCollect(ScreenNames;{Name: "Screen2";ScreenName:Screen2};{Name: "Screen3";ScreenName:Screen3};{Name: "Screen4";ScreenName:Screen4})

On the OnSelect of the buttons in the Gallery, use this formula and you will be directed to the correct screen:
Navigate(LookUp(ScreenNames;Name = ThisItem.Screen;ScreenName);ScreenTransition.Cover)

Hi @Mats_1997 ,

Do you want to navigate to different screens based on selected item's field value?

Please notice one thing: Navigate function's syntax:
Navigate(screenname)

The screenname in this function should be constant value. Using "ThisItem.Screen" in it is not supported.

How to solve this? I suggest you use If statement to justify navigate to which screen.

Try this:
set the gallery buttons OnSelect:

If(ThisItem.Screen="Screen1",Navigate(Screen1), ThisItem.Screen="Screen2",Navigate(Screen2), ThisItem.Screen="Screen3",Navigate(Screen3) )

Best regards,
