I noticed a peculiar problem. NumericUpDown has lost both buttons after having been scrolled out of view.
I have not succeeded in making a screenshot so far. The buttons disappear, the underlined value remains, the line continuing on the former location of the buttons.
This is my simplified code.
<ScrollView VerticalOptions="Fill">
<ListView ItemsSource="{Binding Items}" HasUnevenRows="True" BackgroundColor="White">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<StackLayout Orientation="Vertical" Padding="5,0">
<StackLayout Orientation="Horizontal">
<NumericUpDown:SfNumericUpDown Value="{Binding Quantity, Mode=TwoWay}" VerticalOptions="Center" HorizontalOptions="Start" WidthRequest="130" FontSize="15" FontAttribute="Bold" TextColor="Black"/>
</StackLayout>
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</ScrollView>
