Examples

Here, we declare a StrokeStarted listener.

inkCanvas.InkPresenter.StrokeInput.StrokeStarted += StrokeInput_StrokeStarted;

We then define the corresponding handler, which clears any selected strokes when a new ink stroke is started.

private void StrokeInput_StrokeStarted(InkStrokeInput sender, Windows.UI.Core.PointerEventArgs args)
{
  var strokes = inkCanvas.InkPresenter.StrokeContainer.GetStrokes();
  foreach (var stroke in strokes)
  {
    stroke.Selected = false;
  }
  ClearDrawnBoundingRect();
}
