当我点击它以外，如何关闭子窗口？
答案 0 :(得分：5)
如果您使用的是默认的silverlight子窗口样式，则在打开时，外部部分（透明灰色部分）实际上是子窗口样式中的Grid（称为Overlay）。
所以你需要做的是处理它的MouseLeftButtonDown事件，
<Grid x:Name="Overlay" Background="{TemplateBinding OverlayBrush}" HorizontalAlignment="Stretch" Margin="0" Opacity="{TemplateBinding OverlayOpacity}" VerticalAlignment="Top" MouseLeftButtonDown="Overlay_MouseLeftButtonDown"/>
在后面的代码中，你做了
private void Overlay_MouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
this.Close();
}
我也复制了这里的风格以防万一。 ：）

您可以尝试使用LostFocus事件。
