I've a list of actions in ListView each containing RangeSlider for marking progress by user. But the Ticks & Labels are not displayed (in UWP & iOS. I've not tested on Android). Tick & Label is displayed if its used outside ListView. Here is the code:
<ListView ItemsSource="{Binding ActionSteps}" SelectedItem="{Binding SelectedActionStep, Mode=OneWayToSource}"
HasUnevenRows="True">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<Grid Padding="0,15,0,0">
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<StackLayout>
<Label Text="{Binding Action}"/>
<rangeSlider:SfRangeSlider ShowValueLabel="True" ValuePlacement="TopLeft" TickPlacement="TopLeft" SnapsTo="Ticks" TickFrequency="1"
Minimum="0" Maximum="{Binding Repetitions}"
ShowRange="False" Value="{Binding CompletedRepetitions, Mode=TwoWay}"
HeightRequest="20" Margin="0,0,200,0" Orientation="Horizontal"/>
</StackLayout>
<Label Grid.Row="1" Text="{Binding Quote.Statement}" TextColor="Gray" FontSize="10"/>
</Grid>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
