尝试绑定加载的子类事件处理程序时发生XamlParseException

在我的Windows Phone项目中，我遇到了同样的问题：

但是，我的处理程序似乎有正确的签名

更奇怪的是，我在另一个页面上对UIElement_Tap事件做了同样的事情，效果很好

MainPage.xaml

<v:PageBase
    x:Class="PhoneApp1.Views.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    <Grid x:Name="LayoutRoot" Background="Transparent">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>

        <ItemsControl Grid.Row="0"
                      Loaded="ItemsControl_Loaded"
                      Margin="0,0,0,120">

            <TextBlock Text="Item1"/>
            <TextBlock Text="Item2"/>
            <TextBlock Text="Item3"/>

        </ItemsControl>

        <ItemsControl Grid.Row="1"
                      Loaded="ItemsControl_Loaded"
                      Margin="0,120,0,0">

            <TextBlock Text="Item1"/>
            <TextBlock Text="Item2"/>
            <TextBlock Text="Item3"/>
            <TextBlock Text="Item4"/>

        </ItemsControl>

    </Grid>

</v:PageBase>

PageBase.cs

using Microsoft.Phone.Controls;

namespace PhoneApp1.Views
{
    // Common code across pages.
    public class PageBase : PhoneApplicationPage
    {
        protected virtual void ItemsControl_Loaded(object sender, System.Windows.RoutedEventArgs e    )
        {
            //...
        }
    }
}

我知道我可以重写该方法并在主页中调用基类型，但这违背了使用公共基的目的，不是吗？

这就是我最终解决此问题的原因： 为itemscontrol指定了一个名称，并将事件连接到主页构造函数中：

---

itemControl1.Loaded+=base.ItemsControl\u Loaded

尝试用EventArgs替换System.Windows.RoutedEventArgs

using Microsoft.Phone.Controls;

namespace PhoneApp1.Views
{
    // Common code across pages.
    public class PageBase : PhoneApplicationPage
    {
        protected virtual void ItemsControl_Loaded(object sender, System.Windows.RoutedEventArgs e    )
        {
            //...
        }
    }
}
