找到在WPF中引发MouseEvent的元素名称

Question

我有这样的XAML：

<Border x:Name="ModelWindowBorder" ClipToBounds="True" MouseWheel="Func">
</Border>

在代码背后：

private void Func(object sender, MouseWheelEventArgs e)
{
  // how can I get the element name that raised this event? (ie ModelWindowBorder)
}

Answer 1

您通过sender参数获取元素：

private void Func(object sender, MouseWheelEventArgs e)
{
    var element = (UIElement)sender;
}

如果您想获取其名称，可以转为FrameworkElement而不是UIElement并访问Name媒体资源：

private void Func(object sender, MouseWheelEventArgs e)
{
    var element = (FrameworkElement)sender;
    var name = element.Name;
}

Answer 2

试试这个。

private void Func(object sender, MouseWheelEventArgs e)
{
   var name = (sender as Border).Name;
}
