.net - 将命令分配给 EventSetter

Question

如何给EventSetter中的Handler分配一个命令，我想这样写:

<Style x:Key="ItemStyle" TargetType="{x:Type ListBoxItem}">
            <EventSetter Event="PreviewMouseDoubleClick" Handler="{Binding MyDoubleClickCommand}"/>            

Answer 1

试试 Marlon 的 Grech 的 attached commands behaviours ，如本文所述 previous question.

或者，作为更简单但不太灵活的解决方案，请提供 Handler在代码隐藏中实现直接引发命令，如下所示:

<!-- In the XAML -->
<EventSetter Event="PreviewMouseDoubleClick" Handler="MyPreviewDoubleClickHandler"/>

// In the code-behind
private void MyPreviewDoubleClickHandler(object sender, RoutedEventArgs args) {
    object my_param = ...;
    MyCommand.Execute(my_param, this);
}
