multiple galleries one text input for result

[Guts]

hello, I have multiple galleries in my application which once I click on an item in gallery one its ID is shown in this particular text input that has by default the code "Gallery1.selected.ID" the problem is if I click on an item in gallery 2 obviously it wont show the new ID is there an OR function i could use or something here in this situation ?

I tried doing Gallery1.selected.ID || Gallery2.selected.ID and it now returns false in the text input.

Hi @Guts ,

I feel you are trying to achieve the selected ID as result but it depends on the last gallery record you selected.

If I'm correct then you can do the following:

Step 1: For any gallery that you have, mention this formula

UpdateContext({varSelectedID: Self.Selected.ID});

Step 2: Use this variable 'varSelectedID' in the Textbox in Default property

But, if you have different unique ID column name then try the following:

Then use proper 'Self.Selected.<column name>' then for respective galleries.

NOTE: Self keyword is I'm assuming you are selecting Gallery, else you can Hard-code your Gallery name in OnSelect Property

Hope this helps

yes you got the idea right I tried typing your code in my gallery but it returned this error "Behavior function is a non-behavior property. You can't use this property to change values elsewhere in the app".

Hi @Guts ,

Looks like you are using these galleries on mulitple screens.

Since UpdateContext only works on Active screen.

Try setting variable globaly in App by using Set() function

Below is the syntax

Set(varSelectedID, Gallery.Selected.ID);

Hope this helps

I think I need to explain it more then I have multiple galleries in multiple screens each but they will all take me to the same screen all these galleries have a field called "No" or ID lets just say , If I click on an item in Gallery1 the text input shows its ID perfectly cause by default I have it set on "Gallery1.selected.No" but if now I click on an item in another gallery it will take me the screen but it will still have the ID from Gallery1 I tried using your last solution :

but its the same as typing Gallery1.selected.No . I am sorry if I misunderstood your steps

Yea @Guts ,

So let's say you have 3 galleries on 3 screen that when you select on any of them it takes you to a screen that should show last selected ID.

So,

//For OnSelect property of Gallery1 on Screen 1
Set(varSelectedID, Gallery1.Selected.ID);

//For OnSelect property of Gallery2 on Screen 2
Set(varSelectedID, Gallery2.Selected.ID);

//For OnSelect property of Gallery3 on Screen 3
Set(varSelectedID, Gallery3.Selected.ID);

//....and so on

By doing this, you global variable will contain your last selected output.

Hope this helps
