Remarks
Control templates provide reusable styling and functionality for common UI elements in an application. They do this by providing a common set of properties that bind to the parents of the View that owns the View to which the control template is bound.
Application developers can assign these properties through XAML, as in the following example:
<ControlTemplate x:Key="LoginTemplate">
<StackLayout VerticalOptions="CenterAndExpand" Spacing="20" Padding="20">
<Entry Text="{TemplateBinding Username}" Placeholder="Username" />
<Entry Text="{TemplateBinding Password}" Placeholder="Password" />
<Button Command="{TemplateBinding Command}" Text="Click Here To Log In" />
</StackLayout>
</ControlTemplate>
Additionally, application developers can use the SetBinding(DataTemplate, BindableProperty, String) static method to set template bindings in code.
