问题描述
现在我有一个用户控件按钮。点击该按钮将会启动一个窗口，如下所示：
Right now I have button on a usercontrol. Clicking that button will launch a window as follows,
private void Button_Click(object sender, RoutedEventArgs e)
{
this.Effect = new BlurEffect();
dlg = new WidgetWindow();
dlg.Owner = Window.GetWindow(this);
dlg.Show();
this.Effect = null;
}
现在请参阅图片。每当我点击窗口小部件窗口外部，即任何时候我点击用户控件的灰色区域，我想要关闭圆形窗口小部件窗口。我试图为用户控件提出一个事件，如下所示，但事件不会触发。我也试过鼠标没有运气。我也试着将事件提升到用户控件的子容器，这是在我的情况下，但事件不会提高。请帮助
Now please see the Image. Whenever I click outside the widget window i.e. anytime I click on the grayed out area of the usercontrol, I want the circular widget window to close. I am trying to raise an event for the usercontrol as follows but the event never fires. I also tried mouse down with no luck. I also tried raising the events to the child container of the usercontrol which is Grid in my case but the event wont raise. Please help
private void Tbl_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
if (dlg != null)
{
dlg.Close();
}
}
这是WidgetWindow的代码。

推荐答案
您可以使用Popup代替WidgetWindow。将所有的WidgetWindow内容放入弹出窗口。配置Popup Staysopen =False。您可以参考以下代码：
You can use Popup instead of WidgetWindow. Put all your WidgetWindow content into Popup. Configure Popup Staysopen="False". You can refer to below code:
<Popup Name="popLink" StaysOpen="False" Placement="Mouse" MaxWidth="200"
PopupAnimation="Slide" AllowsTransparency="True">
...Your content
</Popup>
使用popLink.IsOpen = true打开它。
Use popLink.IsOpen = true to open it.
