WPF 使用EventTrigger设置Item的IsSelected选项

 <Grid>
        <ListBox x:Name="c"  >
            <ListBox.ItemContainerStyle>
                <Style TargetType="ListBoxItem">
                    <Style.Triggers>
                        <EventTrigger RoutedEvent="Selected">
                            <BeginStoryboard>
                                <Storyboard Storyboard.TargetProperty="IsSelected">
                                    <BooleanAnimationUsingKeyFrames>
                                        <DiscreteBooleanKeyFrame KeyTime="0:0:0:0.1">
                                            <DiscreteBooleanKeyFrame.Value>
                                                <num:Boolean>False</num:Boolean>
                                            </DiscreteBooleanKeyFrame.Value>
                                        </DiscreteBooleanKeyFrame>
                                    </BooleanAnimationUsingKeyFrames>
                                </Storyboard>
                            </BeginStoryboard>
                        </EventTrigger>
                    </Style.Triggers>
                </Style>
            </ListBox.ItemContainerStyle>
            <ListBoxItem Content="AAAA"  />
            <ListBoxItem Content="BAAA" />
            <ListBoxItem Content="ACAAA"/>
            <ListBoxItem Content="ADAA" />
            <ListBoxItem Content="AEAA"/>
        </ListBox>
    </Grid>
