Windows requirements

API contract	Windows.Foundation.UniversalApiContract (introduced in v1.0)

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();
}

Properties

InkPresenter

Gets the InkPresenter object associated with the ink input data.

Events

StrokeCanceled	Occurs when ink input bubbles up to another system event handler, such as a context menu.
StrokeContinued	Occurs when stroke input has started (StrokeStarted) and continues to be captured by an InkPresenter object.
StrokeEnded	Occurs when stroke input has stopped being detected by an InkPresenter object.
StrokeStarted	Occurs when stroke input is first detected by an InkPresenter object.
