SFListivew in ScrollView disappears items

[David]

Good afternoon, I have a problem with the SFListView, in the code that I show, everything worked correctly, when the search button is pressed, the client data is shown in the listview, if I press search again, the new data is displayed in the list view.

The problem is when I try to add a ScrollView after the buttons, the first search is displayed without problems in the listview, but I press the search button again, the listview seems to load but the items are not shown.

I already tried adding : HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand"

and : VerticalOptions="EndAndExpand".
