How to retain selection in Gallery + Form on DB refresh

I am using CDS & have a screen with a Gallery & Form. The selected gallery item populates the form & the form can be edited.

My problem is however, that the gallery selection gets lost when I execute Refresh(Database).

Is there a way either to retain the gallery selection when a form is submitted, or to re-select the previous item after a form has been edited (and the database refreshed)?

Thanks!

Hi @Medoomi,

 

What you can do for the OnSelect() of your Refresh Button is something like this:

Set(varSelectedItemID, Gallery1.Selected.Id);
Refresh(Database)

 

Now on the Default() of you Gallery you can do something like this:

LookUp(Database, Id = varSelectedItemID)

 

Hope this helps.

Try these steps:
1. OnVisible of the screen put: 

UpdateContext({GallerySelected:!GallerySelected})
 
2. Insert another Gallery say Gallery4 and on its items put:
Form1.LastSubmit ....(Form1 to your actual form name)
 
3.Finally on the Item of the Form1 put:

If(GallerySelected,Gallery4.Selected,If(!GallerySelected,Gallery2.Selected))

Change Gallery2 to your existing Gallery connected to the form

Thanks so much for your answer. I'm trying to understand the process. Am I correct thinking that Gallery4 would become a kind of "holding place" for the previously submitted form... So in practice, once the form was submitted, while Gallery2 might become de-selected, the form selection would remain?

The idea is to be able to choose from either Gallery2  which holds the existing record and Gallery 4 which holds the latest submitted item. 

You have a choice of selection between the two at any point in time.
