Constructors

ModelItemDictionary()

Creates a new ModelItemDictionary.

Fields

KeyProperty

The DependencyProperty that represents the key in the key/value pair that is added to all items in the dictionary. The data type of the KeyProperty is ModelItem.

Properties

Attributes	Gets the attributes declared on this item. (Inherited from ModelItem)
Content	Gets the `ContentPropertyAttribute` of the item, or `null`. (Inherited from ModelItem)
Count	Returns the count of items in the dictionary.
IsFixedSize	Determines whether the dictionary is a fixed size.
IsReadOnly	Determines whether the dictionary cannot be modified.
IsSynchronized	Gets a value that indicates whether access to the dictionary is synchronized (thread safe).
Item[ModelItem]	Gets or sets the item at the specified key.
Item[Object]	Gets or sets the item at the specified key.
ItemType	Gets the type of object that the item represents. (Inherited from ModelItem)
Keys	Gets the keys of the collection. The keys are guaranteed to be in the same order as the values. The resulting collection is read-only.
Name	Gets or sets the name or ID of the item. (Inherited from ModelItem)
Parent	Gets the item that is the parent of this item. (Inherited from ModelItem)
Parents	Gets all parents of this item. (Inherited from ModelItem)
Properties	Gets the public properties on this item. (Inherited from ModelItem)
Root	Gets the item that is the root of this tree. (Inherited from ModelItem)
Source	Gets the property that provided this value. (Inherited from ModelItem)
Sources	Gets all the properties that hold this value. (Inherited from ModelItem)
SyncRoot	Gets an object that can be used to synchronize access to this collection.
Values	Gets the values of the collection.
View	Gets a DependencyObject that graphically represents this item. (Inherited from ModelItem)

Methods

Add(ModelItem, ModelItem)	Adds the value to the dictionary under the given key.
Add(Object, Object)	Adds the value to the dictionary under the given key. This method wraps the key and value in a set of ModelItem objects.
BeginEdit()	Opens an editing scope for the designer. After an editing scope is open, all changes across all objects will be saved into the scope until the transaction is completed or reverted. Editing scopes can be nested, but must be committed in order. (Inherited from ModelItem)
BeginEdit(Boolean)	Opens an editing scope for the designer. (Inherited from ModelItem)
BeginEdit(String)	Opens an editing scope for the designer. After an editing scope is open, all changes across all objects will be saved into the scope until the transaction is completed or reverted. Editing scopes can be nested, but must be committed in order. (Inherited from ModelItem)
BeginEdit(String, Boolean)	Opens an editing scope for the designer. (Inherited from ModelItem)
Clear()	Clears the contents of the dictionary.
Contains(KeyValuePair<ModelItem,ModelItem>)	Determines whether the dictionary contains the given key/value pair.
ContainsKey(ModelItem)	Determines whether the dictionary contains the given key.
ContainsKey(Object)	Determines whether the dictionary contains the given key.
CopyTo(KeyValuePair<ModelItem,ModelItem>[], Int32)	Copies an array of key/value pairs into the given dictionary.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetCurrentValue()	Returns the current value of the underlying model object that the ModelItem is wrapping. (Inherited from ModelItem)
GetEnumerator()	Returns an enumerator for the items in the dictionary.
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
Remove(ModelItem)	Removes the item with the specified key from the dictionary.
Remove(Object)	Removes the item from the dictionary.
ToString()	Returns a string representation of the underlying model object contained in this model item. (Inherited from ModelItem)
TryGetValue(ModelItem, ModelItem)	Retrieves the value for the given key, if possible.
TryGetValue(Object, ModelItem)	Retrieves the value for the given key, if possible.

Events

CollectionChanged	Raised when the contents of this collection change.
PropertyChanged	Implements `INotifyPropertyChanged`. Use this event to listen for changes to the model. This is also used by the data binding features of WPF. (Inherited from ModelItem)

Explicit Interface Implementations

ICollection.CopyTo(Array, Int32)	Copies the elements of the ICollection to an array, starting at a particular array index.
ICollection.Count	Gets the number of elements contained in the ICollection.
ICollection.IsSynchronized	Gets a value that indicates whether access to the ICollection is synchronized (thread safe).
ICollection.SyncRoot	Gets an object that can be used to synchronize access to the ICollection.
ICollection<KeyValuePair<ModelItem,ModelItem>>.Add(KeyValuePair<ModelItem,ModelItem>)	Adds a new element to the end of the collection.
ICollection<KeyValuePair<ModelItem,ModelItem>>.Contains(KeyValuePair<ModelItem,ModelItem>)	Determines whether the dictionary contains the given key/value pair.
ICollection<KeyValuePair<ModelItem,ModelItem>>.CopyTo(KeyValuePair<ModelItem,ModelItem>[], Int32)	Copies an array of key/value pairs into the given dictionary.
ICollection<KeyValuePair<ModelItem,ModelItem>>.Remove(KeyValuePair<ModelItem,ModelItem>)	Removes the specified key/value pair from the dictionary.
