Class
Definition
Provides properties and methods to store and manage the collection of InkStroke objects rendered by the InkPresenter.
Modifications made to any of the ink strokes in the stroke container are immediately rendered to the drawing surface associated with the InkPresenter.

Remarks
For ink recognition, use an InkRecognizerContainer object.
The StrokesCollected event is fired when ink strokes are processed ("wet" to "dry") on the UI thread.
Note
: This class is not agile, which means that you need to consider its threading model and marshaling behavior. For more info, see Threading and Marshaling (C++/CX) and Using Windows Runtime objects in a multithreaded environment (.NET).

Remarks
The following can result from a call to MoveSelected:
- Moving one or more strokes that make up part of a word results in the reprocessing of existing ink recognition results.
- Moving all strokes that make up a word results in the recalculation of the BoundingRect of the InkRecognitionResult. Ink recognition is not reprocessed.
- Moving one or more strokes results in the recalculation of the BoundingRect for each stroke.
- Moving one or more strokes results in the recalculation of the BoundingRect of the InkStrokeContainer.
