Gallery content not clearing data

Good day.

I have an app the populates its content based on based on a selection in another gallery which lives in a different screen.

The user starts navigation in Screen 1 and selects an item in glr_Ideas

Then Navigates to Screen 2

Where glr_comments populates its item using this formula

Filter('DataSource',CommentID=glr_Ideas.Selected.ID)

If the user navigates to screen 1 and makes another selection, upon navigating to screen 2, they will see the items from the previously selected item for about 1 second until the query is updated.

Is there a way to avoid this?

Hi @GreenJaguar ,

Can you try passing as arguments as context to Screen 2?
So for your OnSelect property in 'glr_Ideas'
Navigate(Screen2, <some - transition>, {GalSelectedRecord: ThisItem})
On next screen you will have GalSelectedRecord variable which you can use as source of data.

OR

you can Set a Variable then you can Navigate and later use the variable

Hope this helps

Thanks @Ethan_R
Could not quite get it to work, but I did find a workable solution.
When a user loads the Home Screen I set the On-Visible=Clear(col_Comments) [a comments collection]
When user interacts with the comments icon in the Gallery, I set the OnSelect to
Collect(col_Comments,Filter('Idea Comments',CommentID=glr_Ideas.Selected.ID)); Navigate(Screen 2)
The Items in the Comments gallery are set to Items=col_Comments

As the user navigates back to the home screen the collection is cleared
