Remarks
When programming with .NET, this class is hidden and developers should use the System.Collections.Specialized.NotifyCollectionChangedEventArgs class.
NewStartingIndex will contain the following values, depending on the Action being reported in the event data.
| Action | Value |
|---|---|
| Add | The index of the newly added item. |
| Move | The index of the newly added item. Because a Move can logically be considered a virtual Remove followed by a virtual Add, the index reported here might already be adjusted for the virtual Remove. |
| Remove | -1 |
| Replace | The index of the replaced item. |
| Reset | -1 |
Note that this value is signed. This enables the -1 value cases.
