将命令分配给EventSetter

Question

如何在EventSetter中将命令分配给处理程序，我想写成：

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

Answer 1

试试这个previous question.中提到的Marlon的Grech's attached commands behaviours

或者，作为一种更简单但灵活性较差的解决方案，可以在代码隐藏中提供一个Handler实现来直接引发命令，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);
}
