将 UserControl 中的事件绑定到父级 Window- 路由事件 - C# XAML

Bind an event from a UserControl into the parent Window- Routed events - C# XAML

我在堆栈面板中有多个相同用户控件的实例,每个用户控件中都有一个按钮。

当我单击此按钮时,我希望它打开一个新的 window,然后禁用包含所有用户控件的堆栈面板,这样就无法打开此 window 的多个实例同一时间。然后我希望能够在用户关闭新打开的 window 时重新启用堆栈面板。

目前我有这段代码,当我的按钮位于主 Window XAML 而不是用户控件的一部分时:

private void ButtonClick(object sender, RoutedEventArgs e)
{
    RouteViewer Rv = new RouteViewer((sender as Button).Tag).ToString());
    Rv.Owner = this;
    Rv.Show();

    StackPanel.IsEnabled = false; //Disables the stackpanel 
    Rv.Closed += new EventHandler(RvClosed);
}

void RvClosed(object sender, EventArgs e)
{
    StackPanel.IsEnabled = true; //Re-enables the stackpanel
}

如您所见,问题是由于堆栈面板不属于用户控件。我一直在谷歌搜索并怀疑答案与路由事件有关,我们将不胜感激。

看看这个网站 here,你会想使用事件 "Bubbling"。

代码可能如下所示: C# 在用户控件中:

private void ButtonClick(object sender, RoutedEventArgs e)
{
    RouteViewer Rv = new RouteViewer(((sender as Button).Tag).ToString());
    Rv.Show();

    var newEventArgs = new RoutedEventArgs(RvOpenedEvent);
    RaiseEvent(newEventArgs);
}



public static readonly RoutedEvent RvOpenedEvent = EventManager.RegisterRoutedEvent(
    "RvOpened",
    RoutingStrategy.Bubble, 
    typeof(RoutedEventHandler), 
    typeof(ClassName)); 

public event RoutedEventHandler RvOpened
{
    add { AddHandler(RvOpenedEvent, value); }
    remove { RemoveHandler(RvOpenedEvent, value); }
}

然后在 Main Window XMAL :

<UserControl:Name RvOpened="RouteViewerOpened"/>

然后在 Main Window C#:

private void RouteViewerOpened(object sender, RoutedEventArgs e)
{
    ServiceStack.IsEnabled = false;
    e.Handled = true;
}
