How can I specify the order in which groups are displayed in the RadListView? The control is automatically sorting my groups alphabetically (regardless of the order in which my items of a specific group are added to my collection), which I really don't want. In fact, my goal is to always have the groups in a specific order that cannot be re-ordered, and I want to specify this order explicitly. That is, it's not an ascending or descending order, but an arbitrary one that I specify.
Here's my XAML:
I'm using Telerik UI for Xamarin 2020.1.218.1, Xamarin Forms 188.8.131.520.
