Compiled bindings in .NET MAUI require setting x:DataType on the root XAML element to enable type-safe ViewModel property binding. This improves performance by validating binding paths at compile time, reducing runtime errors across Pages and DataTemplates.

Transform bound data in a MAUI UI by implementing IValueConverter classes for custom data transformations. You can also apply StringFormat directly in XAML to format display values without modifying the underlying ViewModel properties.

Relative bindings in MAUI allow a control to bind to properties on a different object than its direct BindingContext, such as a parent element. This is essential for complex data compositions and templating scenarios where nested data relationships exist.

MultiBinding allows you to bind multiple ViewModel properties to a single MAUI control by combining values. Use a ValueConverter to define how these multiple input values should be composed into the final target property value.

MAUI supports OneWay, TwoWay, OneTime, and OneWayToSource binding modes for ViewModel synchronization. OneTime reads data once for performance, while FallbackValue and TargetNullValue properties define UI behavior when bound data is missing or null.
