gum-runtime-binding

Configure Gum runtime data binding by setting a BindingContext on GraphicalUiElement visuals or FrameworkElement form controls. The context automatically cascades to descendants, enabling string, object, and lambda bindings for two-way UI synchronization without external dependencies.

GraphicalUiElement supports simple string bindings for visuals, while FrameworkElement offers richer form control bindings using strings, Binding objects, and lambda expressions. FrameworkElement provides advanced features like configurable binding modes and converters.

Bind a TextBox property using a lambda expression by passing the expression to the FrameworkElement binding setup. Gum extracts the static property path from the lambda to establish two-way synchronization between the form control and the view model.

Gum runtime binding supports indexed path syntax and reacts to collection change notifications. This allows UI elements to dynamically update when underlying collections change, including handling out-of-bounds indexes during data synchronization.

Gum manages memory in deep property path bindings using weak listener management. This prevents memory leaks when tracking property changes across nested objects within the binding context cascade.

BindableGue is deprecated in Gum's binding system because FrameworkElement and GraphicalUiElement now provide native runtime binding capabilities. This shift allows direct binding context setup and lambda support without requiring a separate bindable wrapper component.
