version Xamarin.Forms.3.1.0.637273 and Xamarin.Forms 3.1.0.583944
I want to use the DataTemplateSelector for the GroupHeaderTemplate.
<ListView Grid.Row="1" ItemsSource="{Binding PickerGroups}" IsGroupingEnabled="True" ItemTemplate="{StaticResource PickerDataTemplateSelector}"
GroupHeaderTemplate="{StaticResource PickerDataTemplateSelector}" CachingStrategy="RecycleElementAndDataTemplate">
</ListView>
I get here such a crash:
ListProxy.get_Item (System.Int32 index)
D:\a\1\s\Xamarin.Forms.Core\ListProxy.cs - line 127
