我在给定代码的View部分中使用了事件触发器,如下所示.几乎所有绑定都可以通过ViewModel类-MainWindowViewModel正确地进行,但是对于方法“ CustomRibbonWindow_Loaded”,其抛出的运行时异常如下：

Microsoft.Expression.Interactions.dll中发生类型为’System.ArgumentException’的异常,但未在用户代码中处理
附加信息：在“ MainWindow”类型的对象上找不到与预期签名匹配的名为“ CustomRibbonWindow_Loaded”的方法.
如果有用于此异常的处理程序,则可以安全地继续执行该程序.

我试过把TargetObject =“ {Binding ElementName = RR}”以及TargetObject =“ {Binding}”也放进去.但是似乎没有任何作用.

我在VM中的方法如下

private void CustomRibbonWindow_Loaded()
    {
       ...
    }

请指导如何解决.

<i:Interaction.Triggers>
    <i:EventTrigger EventName="Loaded">
        <si:CallMethodAction MethodName="CustomRibbonWindow_Loaded"/>
    </i:EventTrigger>

</i:Interaction.Triggers>

   ...

</custom:CustomRibbonWindow>

解决方法:

像这样进行方法订阅.

private void Window_Loaded(object sender, RoutedEventArgs e) 
// add the proper parameters
{
    // code here
}
