命名空间:

System.Windows.Controls

程序集:

PresentationFramework.dll

在用户擦除笔画时发生。

public:
 event System::Windows::RoutedEventHandler ^ StrokeErased;

public event System.Windows.RoutedEventHandler StrokeErased;

member this.StrokeErased : System.Windows.RoutedEventHandler 

Public Custom Event StrokeErased As RoutedEventHandler

RoutedEventHandler

示例

以下示例报告事件发生时 StrokeErased 在 上的InkCanvas笔划数。 如果 EditingMode 设置为 EraseByPoint ，并且用户擦除了笔划的中间，则 上的 InkCanvas 笔划数将增加。 这是因为旧笔划已替换为两个新笔划。

void inkCanvas1_StrokeErased(object sender, RoutedEventArgs e)
{
    Title = "Stroke erased " + inkCanvas1.Strokes.Count.ToString();
}

Private Sub inkCanvas1_StrokeErased(ByVal sender As Object, ByVal e As RoutedEventArgs)

    Me.Title = "Stroke erased " + inkCanvas1.Strokes.Count.ToString()

End Sub

注解

当用户擦除墨迹时，无论 EditingMode 属性设置为 EraseByPoint 还是 EraseByStroke，都会出现此事件。
