Public Methods

Method	Description
Add ( UIElement element ) : int	Adds the element to the DisconnectedUIElementCollection
Clear ( ) : void	Removes all elements from the DisconnectedUIElementCollection
Contains ( UIElement element ) : bool	Determines whether an element is in the DisconnectedUIElementCollection
CopyTo ( Array array, int index ) : void	Copies the collection into the Array
CopyTo ( UIElement array, int index ) : void	Strongly typed version of CopyTo
DisconnectedUIElementCollection ( UIElement owner ) : System	This collection can be used by a panel to maintain a collection of child elements that are not connected to their owner as visual children or logical children.
GetEnumerator ( ) : IEnumerator	Returns an enumerator that can iterate through the collection.
IndexOf ( UIElement element ) : int	Returns the index of the element in the DisconnectedUIElementCollection
Initialize ( ) : void	The Initialize method is simply exposed as an accessible member that can be called from the ConceptualPanel's Loaded event. Accessing this member via the Children property will implicitly cause CreateUIElementCollection to be called to create the disconnected collection. This method exists because simple access of a property like Count might be optimized away by an aggressive compiler.
Insert ( int index, UIElement element ) : void	Inserts an element into the DisconnectedUIElementCollection at the specified index
Remove ( UIElement element ) : void	Removes the specified element from the DisconnectedUIElementCollection
RemoveAt ( int index ) : void	Removes the element at the specified index from the DisconnectedUIElementCollection
RemoveRange ( int index, int count ) : void	Removes the specified number of elements starting at the specified index from the DisconnectedUIElementCollection
this ( int index ) : UIElement

Method	Description
BaseIndexOf ( UIElement element ) : int
BaseInsert ( int index, UIElement element ) : void
BaseRemoveAt ( int index ) : void
DisconnectedUIElementCollection ( UIElement owner, SurrogateVisualParent surrogateVisualParent ) : System
RaiseCollectionChanged ( NotifyCollectionChangedAction action, object changedItem, int index ) : void
VerifyWriteAccess ( ) : void	If the owner is an items host, we need to enforce the rule that elements cannot be explicitly added to the disconnected collection. However, it is still possible to modify the visual or logical "connected" children of a ConceptualPanel while it is an items host by simply calling the AddVisualChild, RemoveVisualChild, AddLogicalChild, or RemoveLogicalChild methods. Logic within ConceptualPanel ensures that any visual children added in this manner will be returned within a GetVisualChild() enumeration.

Method Details

Add() public method

Adds the element to the DisconnectedUIElementCollection

public Add ( UIElement element ) : int
element	UIElement
return	int

Clear() public method

Removes all elements from the DisconnectedUIElementCollection

public Clear ( ) : void
return	void

Contains() public method

Determines whether an element is in the DisconnectedUIElementCollection

public Contains ( UIElement element ) : bool
element	UIElement
return	bool

CopyTo() public method

Copies the collection into the Array

public CopyTo ( Array array, int index ) : void
array	System.Array
index	int
return	void

CopyTo() public method

Strongly typed version of CopyTo

public CopyTo ( UIElement array, int index ) : void
array	UIElement
index	int
return	void

DisconnectedUIElementCollection() public method

This collection can be used by a panel to maintain a collection of child elements that are *not* connected to their owner as visual children or logical children.

public DisconnectedUIElementCollection ( UIElement owner ) : System
owner	UIElement
return	System

GetEnumerator() public method

Returns an enumerator that can iterate through the collection.

public GetEnumerator ( ) : IEnumerator
return	IEnumerator

IndexOf() public method

Returns the index of the element in the DisconnectedUIElementCollection

public IndexOf ( UIElement element ) : int

Initialize() public method

The Initialize method is simply exposed as an accessible member that can be called from the ConceptualPanel's Loaded event. Accessing this member via the Children property will implicitly cause CreateUIElementCollection to be called to create the disconnected collection. This method exists because simple access of a property like Count might be optimized away by an aggressive compiler.

public Initialize ( ) : void
return	void
