Nikolay's code snippet shows how to change the scrolling direction of the calendar. Since you're using Xamarin.Forms and the TransitionIsVertical
property is on the native iOS TKCalendar control, you'll need to set it using a Xamarin Custom Renderer or Xamarin Effect
You can see an example in the RadCalendar's iOS Custom Renderer article
Note that because Customer Renderers are a general Xamarin.Forms topic and not directly related to the UI for Xamarin feature, we do not have documentation for it. However, you can find a in-depth tutorials and walk-throughs in the Xamarin Custom Renderer documentation
You could also use a Xamarin Effect to access the native control's properties, see the Creating an Effect
Xamarin.Forms documentation for more information and how to get started.
Once you've set up your Effect classes, you could use the OnAttached
method of the Effect to set the value:
ScrollDirectionEffect : PlatformEffect
var tkCalendar = Control
"Cannot set property on attached control. Error: "
// not used
and eventually in the Xamarin.Forms app, you can use the effect:
