protected override void ClearItems()

InsertItem(int, T)

Inserts an element into the Collection<T> at the specified index.

protected override void InsertItem(int index, T item)

Parameters

index int

The zero-based index at which item should be inserted.

item T

The object to insert. The value can be null for reference types.

Exceptions

   <code class="paramref">index</code> is less than zero.  

-or-

index is greater than Count.

MoveItem(int, int)

Moves a given item

public virtual void MoveItem(int oldIndex, int newIndex)

Parameters

oldIndex int

the old index

newIndex int

the new index

OnCollectionChanged(NotifyCollectionChangedEventArgs, bool)

Gets called when the collection was changed

protected virtual void OnCollectionChanged(NotifyCollectionChangedEventArgs e, bool countAffected)

Parameters

e NotifyCollectionChangedEventArgs

the event args

countAffected bool

True, if the Count is also affected, otherwise False

OnCollectionChanging(NotifyCollectionChangedEventArgs)

Gets called when an attempt is made to change the collection
