Ink.InkDeleted Event

Occurs when a Stroke object is deleted from the Ink object.

Namespace:  Microsoft.Ink
Assembly:  Microsoft.Ink (in Microsoft.Ink.dll)

public event StrokesEventHandler InkDeleted

The event handler receives an argument of type StrokesEventArgs that contains data about this event.

When you create a StrokesEventHandler delegate, you identify the method that handles the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate.

If you use the InkOverlay object or the InkPicture control (where EditingMode equals Delete and EraserMode equals StrokeErase) and pass the eraser over a stroke, you get the following sequence of events:

  1. InkDeleted

  2. InkAdded

  3. InkDeleted

The additional InkAdded and InkDeleted events occur because the underlying code adds an internal, invisible stroke to track the eraser.

The InkDeleted event fires even when in select mode, not only when in delete mode. This requires that you monitor the editing mode (which you are responsible for setting) and be aware of the mode before interpreting the event. The advantage of this requirement is greater freedom to innovate on the platform through greater awareness of platform events.

In this example an InkDeleted event handler writes information about the deleted strokes to a list box control.

private void Ink_InkDeleted(object sender, StrokesEventArgs e)
{
    // since this event fires in select mode also, we will check EditingMode 
    // and examine the StrokeIds only if we are currently in mode: InkOverlayEditingMode.Delete  
    if (InkOverlayEditingMode.Delete == this.mInkOverlay.EditingMode)
    {
        foreach (int id in e.StrokeIds)
        {
            this.listBoxStrokeId.Items.Add("Deleted ID:" + id.ToString());

        }
    }
}
