Class KeyboardBindings

Namespace

Nalu

Assembly

Nalu.Maui.Scaffold.dll

The code-behind counterpart of KeyboardBindingExtension: builds bindings to the ambient ScaffoldKeyboardState from anywhere inside the scaffold's element tree.

Remarks

// String path (same reflection semantics as {nalu:KeyboardBinding}):
banner.SetBinding(VisualElement.IsVisibleProperty, KeyboardBindings.Create("IsVisible", converter: new InvertedBoolConverter()));

// Fully typed and compiled (trimming/AOT-safe):
spacer.SetBinding(VisualElement.HeightRequestProperty,
    static (Scaffold s) => s.KeyboardState.Height,
    source: KeyboardBindings.ScaffoldAncestor);

Properties

ScaffoldAncestor

The relative source resolving the nearest ancestor Scaffold — combine it with the typed SetBinding(property, static (Scaffold s) => s.KeyboardState.…, source: KeyboardBindings.ScaffoldAncestor) for fully typed, compiled bindings.

public static RelativeBindingSource ScaffoldAncestor { get; }

Property Value

RelativeBindingSource

Remarks

The keyboard state is scaffold-level (one soft keyboard per window), so unlike the nav bar context there is nothing per-page to resolve here.

Methods

Create(string, BindingMode, IValueConverter?, object?, string?)

Builds a string-path binding into the ambient ScaffoldKeyboardState.
