These properties are backed by BindableProperty objects, which means that they can be targets of data bindings, and styled. TouchCaptureView, of type View, which stores the view responsible for triggering the expansion/collapsing animation, by tap.This property uses the OneWayToSource binding mode. State, of type ExpandState, which represents the state of the Expander.This property uses the TwoWay binding mode, and has a default value of false. IsExpanded, of type bool, which determines if the Expander is expanded.Header, of type View, which defines the header content.ForceUpdateSizeCommand, of type ICommand, which defines the command that's executed when the size of the Expander is force updated.If this property is not set, then the AnimationLength value will be applied. ExpandAnimationLength, of type uint, which defines the duration of the animation when the Expander expands.
ExpandAnimationEasing, of type Easing, which represents the easing function to be applied to the Expander content during expansion.ContentTemplate, of type DataTemplate, which is the template used to dynamically inflate the content of the Expander.Content, of type View, which defines the content to be displayed when the Expander expands.CommandParameter, of type object, which is the parameter that's passed to the Command.Command, of type ICommand, which is executed when the Expander header is tapped.CollapseAnimationLength, of type uint, which defines the duration of the animation when the Expander is collapsing.CollapseAnimationEasing, of type Easing, which represents the easing function to be applied to the Expander content when it's collapsing.The default value of this property is 250ms. AnimationLength, of type uint, which defines the duration of the animation when the Expander is expanding/collapsing.AnimationEasing, of type Easing, which represents the easing function to be applied to the Expander content when it's expanding/collapsing if ExpandAnimationEasing/CollapseAnimationEasing is not set.The Expander control defines the following properties: Therefore, it's available on all platforms supported by Xamarin.Forms. The Expander control is fully implemented in cross-platform code.
