Examples

The following example demonstrates how to set the EditingMode property of an InkCanvas to EraseByStroke when the stylus is inverted. This example assumes that there is an InkCanvas called inkCanvas1 and that the StylusInRange event is connected to the event handlers. To see the cursor change, set the UseCustomCursor property to true on inkCanvas1.

void inkCanvas1_StylusInRange(object sender, StylusEventArgs e)
{
    if (e.StylusDevice.Inverted == true)
    {
        inkCanvas1.EditingMode = InkCanvasEditingMode.EraseByStroke;
        inkCanvas1.Cursor = System.Windows.Input.Cursors.Hand;
    }
    else
    {
        inkCanvas1.EditingMode = InkCanvasEditingMode.Ink;
        inkCanvas1.Cursor = System.Windows.Input.Cursors.Pen;
    }
}

Private Sub inkCanvas1_StylusInRange(ByVal sender As Object, ByVal e As StylusEventArgs) _
    Handles inkCanvas1.StylusInRange

    If e.StylusDevice.Inverted = True Then
        inkCanvas1.EditingMode = InkCanvasEditingMode.EraseByStroke
        inkCanvas1.Cursor = System.Windows.Input.Cursors.Hand
    Else
        inkCanvas1.EditingMode = InkCanvasEditingMode.Ink
        inkCanvas1.Cursor = System.Windows.Input.Cursors.Pen
    End If

End Sub

Remarks

This is an attached event. WPF implements attached events as routed events. An attached event is, fundamentally, a XAML language concept used to reference events that are handled on objects that do not, themselves, define events. WPF further expands an attached event's capabilities, allowing it to traverse a route. Attached events do not have a direct handling syntax in code; to attach handlers for a routed event in code, use a designated Add*Handler method. For details, see Attached Events Overview.
