Remarks
CompositeCollection can contain items such as strings, objects, XML nodes, elements, as well as other collections. An ItemsControl uses the data in the CompositeCollection to generate its content according to its ItemTemplate. For more information about using ItemsControl objects to bind to collections, see the Binding to Collections section of the Data Binding Overview.
Constructors
CompositeCollection() |
Creates a new instance of the CompositeCollection class that is empty and has default initial capacity. |
CompositeCollection(Int32) |
Creates a new instance of the CompositeCollection class that is empty and has a specified initial capacity. |
Properties
Count |
Gets the number of items stored in this collection. |
Item[Int32] |
Indexer property that retrieves or replaces the item at the given zero-based offset in the collection. |
Methods
Add(Object) |
Adds the specified item to this collection. |
Clear() |
Clears the collection. |
Contains(Object) |
Checks to see if a given item is in this collection. |
CopyTo(Array, Int32) |
Makes a shallow copy of object references from this collection to the given array. |
Equals(Object) |
Determines whether the specified object is equal to the current object. (Inherited from Object) |
GetHashCode() |
Serves as the default hash function. (Inherited from Object) |
GetType() |
Gets the Type of the current instance. (Inherited from Object) |
IndexOf(Object) |
Returns the index in this collection where the given item is found. |
Insert(Int32, Object) |
Inserts an item in the collection at a given index. All items after the given position are moved down by one. |
MemberwiseClone() |
Creates a shallow copy of the current Object. (Inherited from Object) |
ReceiveWeakEvent(Type, Object, EventArgs) |
Handles events from the centralized event table. |
Remove(Object) |
Removes the given item reference from the collection. All remaining items move up by one. |
RemoveAt(Int32) |
Removes an item from the collection at the given index. All remaining items move up by one. |
ToString() |
Returns a string that represents the current object. (Inherited from Object) |
Events
