ListBox MouseBinding to Command not working

Question

我想將MouseDoubleClick（或PreviewMouseDoubleClick）綁定到我的自定義命令中，該命令在我的自定義WPF控件中定義。

問題是它不起作用。

... 
<Popup> 
... 
<!--This CommandBinding **DOES NOT WORK** !--> 
<ListBox Grid.Row="1" 
    x:Name="PART_lBox"                  
    VirtualizingStackPanel.IsVirtualizing="True" 
    DisplayMemberPath="{TemplateBinding DisplayMemberPath}"                  
    ItemsSource="{TemplateBinding ItemsSource}"> 
<ListBox.InputBindings>                  
    <MouseBinding Command="{x:Static local:ListPicker.AcceptCommand}"                     
     MouseAction="LeftDoubleClick" /> 
</ListBox.InputBindings> 
</ListBox> 

<!--This CommandBinding **WORKS** !--> 
<Button Grid.Row="0" 
    Grid.Column="1"                   
    HorizontalAlignment="Right" 
    Command="{x:Static local:ListPicker.AcceptCommand}" 
    Content="Accept" /> 
... 
</Popup>
