我有一个列表框如何在页面的相应视图模型中处理keydown事件以删除listItems？我在视野中使用这种鳕鱼:

<ListBox Margin="2,25,2,2" Grid.Row="3" ItemsSource="{Binding Path=CardViewModelSearchResults}" SelectedItem="{Binding Path=SelectedCategoryViewModel, Mode=TwoWay}" IsSynchronizedWithCurrentItem="True">
            <ItemsControl.ItemTemplate>
                <DataTemplate >
                    <Grid>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="*"/>
                            <ColumnDefinition />
                            <ColumnDefinition />
                        </Grid.ColumnDefinitions>
                        <TextBox Grid.Row="0" Grid.Column="0" ff:TextBoxBehaviour.TextChangedCommand="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=UserControl, AncestorLevel=1}, Path=DataContext.TextChanged}" Text="{Binding Path=CategoryName}" FontSize="14" FontWeight="Normal" BorderThickness="0" AllowDrop="False" />
                        <TextBox Grid.Row="0" Grid.Column="1" Text="{Binding Path=CategoryID}" FontSize="14" FontWeight="Normal" Visibility="Hidden" />
                    </Grid>
                </DataTemplate>
            </ItemsControl.ItemTemplate>
        </ListBox>
