Property CanBePinned

Gets a value indicating whether the view model and its associated view can be retained by a RoutePin (see PinCurrentRoute()). Defaults to the value of CanBeCached.

Declaration
bool CanBePinned { get; }
Property Value
Type Description
bool

A pinned view model is navigated to again with its state intact when its route is returned to, so it must handle repeated calls to OnNavigatedToAsync(NavigationArgs) on the same instance in the same way a cached view model does. View models that opt out of caching therefore cannot be pinned unless they explicitly override this property to return true.

When a route is pinned, the leaf view model must be pinnable and each of its ancestors is pinned as well up to the first ancestor that is not pinnable. Ancestors from that point up follow the normal caching rules.
