.NET MAUI - UI Data binding Part - 1 | .NET Multi-platform App | XAMAL | Tutorial For Beginners

Data binding links a pair of properties between two objects, at least one of which is usually a user-interface object. These two objects are called the target and the source.

In the simplest case, data flows from the source to the target.
Bindings with a binding context
Without data bindings, you will have to write event handlers.
The BindingContext property specifies the source object.
The x:Reference markup extension is required to reference the source object,

Binding context inheritance

You can specify the source object using the BindingContext property or the Source property of the Binding object. If both are set, the Source property of the Binding takes precedence over the BindingContext.

The BindingContext property value is inherited through the visual tree.
