RadListView not fitting on iOS

[Namek]

I'm using RadListView for my Xamarin.Forms project, which is targetted to iOS and Android.
The problem is, that on some views, I'm not able to enforce *RadListView* looks "UI fit" on iOS, even using *FillAndExpand* VerticalOptions, packing list to StackLayouts/Grids (also with *FillAndExpand*).

I haven't met anything like that on Android, the problem is only iOS.

When I'm jumping to "standard" Xamarin.Forms *ListView*, list is fitting to the screen on both - iOS and Android.

I'm using latest release of Telerik for Xamarin.Forms - 2016.3.914.

In short, how the UI is build:

At *app.xaml* side, I've feature called *ContentPresenter* in order to have custom toolbar on top of the screen:

<ControlTemplate x:Key="PageHeaderMenuTemplate">
    <Grid RowSpacing="0">
        <Grid.RowDefinitions>
            <RowDefinition Height="50"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>
        <!-- ###### -->
        <!-- Header -->
        <!-- ###### -->
        <StackLayout Grid.Row="0" HeightRequest="50" HorizontalOptions="FillAndExpand" VerticalOptions="Start" Orientation="Horizontal" BackgroundColor="Blue">
            <!-- Header components here -->
        </StackLayout>
        <!-- ########### -->
        <!-- Custom View -->
        <!-- ########### -->
        <StackLayout Grid.Row="1">
            <ContentPresenter HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand"/>
        </StackLayout>
    </Grid>
</ControlTemplate>

Then, I'm using ContentPresenter - *PageHeaderMenuTemplate* on all views, like:

<ContentView ControlTemplate="{StaticResource PageHeaderMenuTemplate}">
  <Grid RowSpacing="0">
    <Grid.RowDefinitions>
      <RowDefinition Height="*"/>
      <RowDefinition Height="50"/>
      <RowDefinition Height="50"/>
    </Grid.RowDefinitions>

    <!-- ######################### -->
    <!-- Page Details View Content -->
    <!-- ######################### -->
    <StackLayout Grid.Row="0" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand" Orientation="Vertical" x:Name="PageDetailsViewContent"/>

    <!-- ################### -->
    <!-- Details Footer -->
    <!-- ################### -->
    <Grid Grid.Row="1" HeightRequest="50" HorizontalOptions="FillAndExpand" VerticalOptions="End" ColumnSpacing="0" BackgroundColor="Aqua">
      <!-- Details Footer components here -->
    </Grid>

    <!-- ###### -->
    <!-- Footer -->
    <!-- ###### -->
    <StackLayout Grid.Row="2" HeightRequest="50" HorizontalOptions="FillAndExpand" VerticalOptions="End" Orientation="Horizontal" BackgroundColor="Blue">
      <!-- Footer components here -->
  </Grid>
</ContentView>

Then in code behind, I'm replacing *PageDetailsViewContent* component, like:

PageDetailsViewContent.Children.Clear();
PageDetailsViewContent.Children.Add(content);

And the content, is build based on below view:

<ContentView
    xmlns="http://xamarin.com/schemas/2014/forms"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:myapp="clr-namespace:Myapp;assembly=Myapp"
    xmlns:dataControls="clr-namespace:Telerik.XamarinForms.DataControls;assembly=Telerik.XamarinForms.DataControls"
    xmlns:listView="clr-namespace:Telerik.XamarinForms.DataControls.ListView;assembly=Telerik.XamarinForms.DataControls"
             x:Class="Myapp.Views.PageDetailsTab.PageDetailsTabAttachmentsView"
             x:Name="PageDetailsTabAttachmentsPage">
    <Grid RowSpacing="0">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>
        <!-- Given Page Additional Header Tab -->
        <StackLayout Grid.Row="0" HorizontalOptions="FillAndExpand" VerticalOptions="StartAndExpand" Orientation="Vertical">
            <!-- Given Page Additional Header Tab components here -->
        </StackLayout>
        <!-- ########### -->
        <!-- RadListView -->
        <!-- ########### -->
        <dataControls:RadListView x:Name="List" Grid.Row="1" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand" ItemsSource="{Binding MyItemsCollection}" BackgroundColor="#ffffff">
            <dataControls:RadListView.ItemTemplate>
                <DataTemplate>
                    <listView:ListViewTemplateCell>
                        <listView:ListViewTemplateCell.View>
                            <Grid HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand" Padding="10,10,10,10">
                                <!-- List Item View Cell components here -->
                            </Grid>
                        </listView:ListViewTemplateCell.View>
                    </listView:ListViewTemplateCell>
                </DataTemplate>
            </dataControls:RadListView.ItemTemplate>
        </dataControls:RadListView>
    </Grid>
</ContentView>

Indeed for this is an issue at iOS, but any workaround for now?

Thanks a lot.

I've found some really ugly/crappy/shitty workaround, to set **HeightRequest** to any "big" number, like:

Device.OnPlatform(iOS: () => List.HeightRequest = 10000);

Any more beauty solution?

Thanks

Hello Namek,

I tried to reproduce the reported behavior on our side with our latest official release and the code seems to be working as expected. I tried the attached project and the results on iOS are the same as the results on Android. Could you please take a look at it and let us know if the results are the same on your side? We would appreciate if you can change the code in a way the issue is reproduced and send it over. This will help us to investigate the reasons behind.
