Base generic class for generalized user-defined behaviors that can respond to arbitrary conditions and events.

public abstract class Behavior<T> : Xamarin.Forms.Behavior where T : BindableObject

type Behavior<'T (requires 'T :> BindableObject)> = class
    inherit Behavior

Type Parameters

T

The type of the objects with which this Behavior<T> can be associated.

Inheritance: Object

BindableObject

Behavior
Behavior<T>

Remarks

Application developers should specialize this generic class, instead of directly using Behavior.

Constructors

Behavior<T>()

Creates a new Behavior<T> instance.

Properties

AssociatedType	Gets the type of the objects with which this Behavior can be associated. (Inherited from Behavior)
BindingContext	Gets or sets object that contains the properties that will be targeted by the bound properties that belong to this BindableObject. (Inherited from BindableObject)
Dispatcher	(Inherited from BindableObject)

Methods

ApplyBindings()	Apply the bindings to BindingContext. (Inherited from BindableObject)
ClearValue(BindableProperty)	Clears any value set by SetValue for `property`. (Inherited from BindableObject)
ClearValue(BindablePropertyKey)	Clears any value set by SetValue for the property that is identified by `propertyKey`. (Inherited from BindableObject)
CoerceValue(BindableProperty)	(Inherited from BindableObject)
CoerceValue(BindablePropertyKey)	(Inherited from BindableObject)
GetValue(BindableProperty)	Returns the value that is contained in the BindableProperty. (Inherited from BindableObject)
GetValues(BindableProperty, BindableProperty)	Obsolete. For internal use by the Xamarin.Forms platform. (Inherited from BindableObject)
GetValues(BindableProperty, BindableProperty, BindableProperty)	Obsolete. For internal use by the Xamarin.Forms platform. (Inherited from BindableObject)
IsSet(BindableProperty)	Returns `true` if the target property exists and has been set. (Inherited from BindableObject)
OnAttachedTo(BindableObject)	Attaches to the superclass and then calls the OnAttachedTo(T) method on this object.
OnAttachedTo(T)	Application developers override this method to implement the behaviors that will be associated with `bindable`.
OnBindingContextChanged()	Override this method to execute an action when the BindingContext changes. (Inherited from BindableObject)
OnDetachingFrom(BindableObject)	Calls the OnDetachingFrom(T) method and then detaches from the superclass.
OnDetachingFrom(T)	Application developers override this method to remove the behaviors from `bindable` that were implemented in a previous call to the OnAttachedTo(T) method.
OnPropertyChanged(String)	Call this method from a child class to notify that a change happened on a property. (Inherited from BindableObject)
OnPropertyChanging(String)	Call this method from a child class to notify that a change is going to happen on a property. (Inherited from BindableObject)
RemoveBinding(BindableProperty)	Removes a previously set binding. (Inherited from BindableObject)
SetBinding(BindableProperty, BindingBase)	Assigns a binding to a property. (Inherited from BindableObject)
SetValue(BindableProperty, Object)	Sets the value of the specified property. (Inherited from BindableObject)
SetValue(BindablePropertyKey, Object)	Sets the value of the propertyKey. (Inherited from BindableObject)
SetValueCore(BindableProperty, Object, SetValueFlags)	For internal use by the Xamarin.Forms platform. (Inherited from BindableObject)
UnapplyBindings()	Unapplies all previously set bindings. (Inherited from BindableObject)

Events

BindingContextChanged	Raised whenever the BindingContext property changes. (Inherited from BindableObject)
PropertyChanged	Raised when a property has changed. (Inherited from BindableObject)
PropertyChanging	Raised when a property is about to change. (Inherited from BindableObject)

Explicit Interface Implementations

IDynamicResourceHandler.SetDynamicResource(BindableProperty, String)

For internal use by the Xamarin.Forms platform.

(Inherited from BindableObject)

Extension Methods

GetPropertyIfSet<T>(BindableObject, BindableProperty, T)
SetAppThemeColor(BindableObject, BindableProperty, Color, Color)
SetBinding(BindableObject, BindableProperty, String, BindingMode, IValueConverter, String)	Creates and applies a binding to a property.
SetBinding<TSource>(BindableObject, BindableProperty, Expression<Func<TSource,Object>>, BindingMode, IValueConverter, String)	Obsolete. Creates and applies a binding from an expression.
SetOnAppTheme<T>(BindableObject, BindableProperty, T, T)
