Class NavBarBindingExtension

Namespace

Nalu

Assembly

Nalu.Maui.Scaffold.dll

Binds to the ambient ScaffoldNavBarContext from anywhere inside the scaffold's element tree — custom bars, and page-parented content hosted in the bar (e.g. a TitleViewProperty view, whose own binding context is the page model): IsVisible="{nalu:NavBarBinding CanNavigateBack}".

Remarks

Resolves the context of the page the target belongs to — page content through its page, bar content (and a hosted title view) through the bar it is mounted in — so during a transition each of the two live pages reads its OWN state. Resolution happens when the target is parented, so declaring the binding before the element is in the tree is fine. Paths naming a ScaffoldNavBarContext property compile to a typed binding; deeper paths (e.g. CurrentPage.BindingContext.SomeCommand) are evaluated by reflection, with the reflected surface preserved under trimming.
