Name | Description | |
---|---|---|

Add | Adds the specified object to the end of the FreezableCollection(Of T). | |

BeginAnimation(DependencyProperty, AnimationTimeline) | Applies an animation to the specified DependencyProperty. The animation is started when the next frame is rendered. If the specified property is already animated, the SnapshotAndReplace handoff behavior is used. (Inherited from Animatable.) | |

OnPropertyChanged | Overrides the DependencyObject implementation of OnPropertyChanged to also invoke any Changed handlers in response to a changing dependency property of type Freezable. (Inherited from Freezable.) | |

ReadLocalValue | Returns the local value of a dependency property, if it exists. (Inherited from DependencyObject.) | |

ReadPreamble | Ensures that the Freezable is being accessed from a valid thread. Inheritors of Freezable must call this method at the beginning of any API that reads data members that are not dependency properties. (Inherited from Freezable.) | |

This class is provided to enable the creation of custom collection types that fully support data binding, change notification, property invalidation, and animation of its contents.

FreezableCollection(Of T) supports a limited XAML syntax.

As an object element at the root, you can theoretically specify an unconstrained FreezableCollection(Of T) object element, which must also specify the x:TypeArguments Directive to declare the constraint. However, this is not a common scenario, because to do this, the FreezableCollection(Of T) must be the root element. This limitation exists because the XAML processor implementation in WPF can only support x:TypeArguments Directive when the element it is being set on is the root element, and you must use x:TypeArguments on any open constraint generic if you want to instantiate a generic type in XAML. It is unlikely that you want a FreezableCollection(Of T) as the root element, even as loose XAML.

If you derive from FreezableCollection(Of T) and apply a type constraint in the derived collection, the derived collection can support a variety of usages. This is possible because the constraint in your derivation eliminates the need to pass x:TypeArguments.

The typical XAML usage for such a derived collection is through implicit collection syntax. Collections that support certain interfaces do not need to specify the collection itself as an object element. For details on collection syntax in XAML, see XAML Syntax In Detail. For instance, an object with a property where the property was of type FreezableCollection(Of T) constrained by DependencyObject could support the following syntax:

<object> <object.property> oneOrMoreDependencyObjectElements </object.property> </object>

As long as you do not hide the default constructor, the derived collection can also support an object element syntax (where the object element is explicit, as opposed to the implicit usage shown above). It does not need to be the root element. Or, you can also use the derived collection as a root element, without needing to specify x:TypeArguments, although using a collection as a root element is uncommon.

Any child elements of the collection in either of the above scenarios must be of the type of either the implemented constraint, or as specified by x:TypeArguments.
