I have a canvas app running off a sharepoint list, on start the app creates a collection from the list and displays it in a gallery.

Users can update items from the list and that is a patch to the list item and also a patch to update the item in the collection.

The problem I am having is when the screen goes back to the gallery screen, it is not showing the updated values for the collection item that was just updated.

What is the best way to update the collection item that has been edited and then refresh the data in the collection before the gallery displays for the user, thanks

@senna,

This is a classic issue when you patch SharePoint and then return to a gallery backed by a cached collection.

Once you patched the data like this its just example patch statement

Patch('Your SharePoint List',Default(),{})

Before you navigating to the gallery screen update the formula.

Refresh('Your SharePoint List');

ClearCollect(yourcollectionname used in item property of gallery, 'Your SharePoint List');

Navigate(GalleryScreen, ScreenTransition.None);

This will resolve your issue.

Thanks @MS.Ragavendar, i was hoping not to have to build my whole collection again, is it not possible to just patch the updated item to the collection and then have the gallery display the updated collection?

@senna,

SharePoint is your datasource -right ?

In PowerApps you creating a collection based on the SharePoint list and you bind the collection to the gallery.

From gallery you are editing the item and updating the data in to the collection and saving back to rendering to the screen.

But the data will be available online offline, what i mean is collection are not persistent storage of table when you close the app the data will not reflected in the backend.

From Gallery - > Edit - > Save the data back to SharePoint list.

Refresh the dataSource using Refresh('your data source')

Try clear collect after refresh and Navigate() or in the gallery screen on visible - ClearCollect()

This would be best practice.

Hi @senna,

You can directly update the collection using the UpdateIf function ,that way you don’t need to rebuild the collection each time.

My general pattern looks like this:

If( !IsBlankOrError( Patch(list, ... ) ), UpdateIf( collection, id = rowidentifier, { ... } ), false )

This ensures the collection is only updated when the item is successfully patched, which helps avoid unnecessary recreation of the collection. It’s a lightweight approach that keeps things efficient.

Hope that helps!
