WPF中触发器（Trigger、DataTrigger）使用动画最简单的方式EnterActions和ExitsActions

1.当鼠标移入后执行某个动画：

<Style TargetType="{x:Type StackPanel}">
                            <Setter Property="RenderTransform">
                                <Setter.Value>
                                    <TranslateTransform X="{Binding ElementName=borderContent,Path=ActualWidth}"/>
                                </Setter.Value>
                            </Setter>
                            
                            <Style.Triggers>
                                <Trigger Property="IsMouseOver" Value="True">
                                    <Trigger.EnterActions>
                                        <BeginStoryboard>
                                            <Storyboard>
                                                <DoubleAnimation To="0"  Duration="0:0:0.2" AccelerationRatio="0.5"  Storyboard.TargetProperty="(UIElement.RenderTransform).(TranslateTransform.X)"/>
                                            </Storyboard>
                                        </BeginStoryboard>
                                    </Trigger.EnterActions>
                                    <Trigger.ExitActions>
                                        <BeginStoryboard>
                                            <Storyboard>
                                                <DoubleAnimation Duration="0:0:0.2" AccelerationRatio="0.5" Storyboard.TargetProperty="(UIElement.RenderTransform).(TranslateTransform.X)"/>
                                            </Storyboard>
                                        </BeginStoryboard>
                                    </Trigger.ExitActions>
                                </Trigger>
                            </Style.Triggers>
                        </Style>
