The CollectionContainer type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | Collection | Gets or sets the collection to add. |
![]() | DependencyObjectType | Gets the DependencyObjectType that wraps the CLR type of this instance. (Inherited from DependencyObject.) |
![]() | Dispatcher | Gets the Dispatcher this DispatcherObject is associated with. (Inherited from DispatcherObject.) |
![]() | IsSealed | Gets a value that indicates whether this instance is currently sealed (read-only). (Inherited from DependencyObject.) |
| Name | Description | |
|---|---|---|
![]() | CheckAccess | Determines whether the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject.) |
![]() | ClearValue(DependencyProperty) | Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier. (Inherited from DependencyObject.) |
![]() | ClearValue(DependencyPropertyKey) | Clears the local value of a read-only property. The property to be cleared is specified by a DependencyPropertyKey. (Inherited from DependencyObject.) |
![]() | CoerceValue | Coerces the value of the specified dependency property. This is accomplished by invoking any CoerceValueCallback function specified in property metadata for the dependency property as it exists on the calling DependencyObject. (Inherited from DependencyObject.) |
![]() | Equals | Determines whether a provided DependencyObject is equivalent to the current DependencyObject. (Inherited from DependencyObject.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Gets a hash code for this DependencyObject. (Inherited from DependencyObject.) |
![]() | GetLocalValueEnumerator | Creates a specialized enumerator for determining which dependency properties have locally set values on this DependencyObject. (Inherited from DependencyObject.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | GetValue | Returns the current effective value of a dependency property on this instance of a DependencyObject. (Inherited from DependencyObject.) |
![]() | InvalidateProperty | Re-evaluates the effective value for the specified dependency property (Inherited from DependencyObject.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | OnContainedCollectionChanged | Raises the CollectionChanged event. |
![]() | OnPropertyChanged | Invoked whenever the effective value of any dependency property on this DependencyObject has been updated. The specific dependency property that changed is reported in the event data. (Inherited from DependencyObject.) |
![]() | ReadLocalValue | Returns the local value of a dependency property, if it exists. (Inherited from DependencyObject.) |
![]() | ReceiveWeakEvent | Handles events from the centralized event table. |
![]() | SetCurrentValue | Sets the value of a dependency property without changing its value source. (Inherited from DependencyObject.) |
![]() | SetValue(DependencyProperty, Object) | Sets the local value of a dependency property, specified by its dependency property identifier. (Inherited from DependencyObject.) |
![]() | SetValue(DependencyPropertyKey, Object) | Sets the local value of a read-only dependency property, specified by the DependencyPropertyKey identifier of the dependency property. (Inherited from DependencyObject.) |
![]() | ShouldSerializeCollection | Indicates whether the Collection property should be persisted. |
![]() | ShouldSerializeProperty | Returns a value that indicates whether serialization processes should serialize the value for the provided dependency property. (Inherited from DependencyObject.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
![]() | VerifyAccess | Enforces that the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject.) |
| Name | Description | |
|---|---|---|
![]() ![]() | INotifyCollectionChanged::CollectionChanged | Occurs when the continaed collection has changed. |
![]() ![]() | IWeakEventListener::ReceiveWeakEvent | This member supports the Windows Presentation Foundation (WPF) infrastructure and is not intended to be used directly from your code. |
The following example shows how to display multiple collections and items as one list using the CompositeCollection class. In this example, GreekGods is an ObservableCollection<T> of GreekGod custom objects. Data templates are defined so that GreekGod objects and GreekHero objects appear with a gold and a cyan foreground color respectively.
