按钮模板，标题抖动

                <ControlTemplate TargetType="{x:Type Button}">
                    <Border x:Name="btn_border" Background="{TemplateBinding Background}" >

                        <TextBlock x:Name="btn_text" Opacity="0" RenderTransformOrigin="0.5,0.5" Text="{TemplateBinding Content}" FontSize="18" FontFamily="Candara" Foreground="Red" FontWeight="Normal" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="0 5 0 0" >
                             <TextBlock.RenderTransform>
                                <RotateTransform></RotateTransform>
                            </TextBlock.RenderTransform>
                        </TextBlock>
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsMouseOver" Value="True">

                        </Trigger>
                        <EventTrigger  RoutedEvent="Button.MouseEnter">
                            <EventTrigger.Actions>
                                <BeginStoryboard>

关键在与在需要变换的元素内声明 元素中心 RenderTransformOrigin(0.5,0.5)

<XX.RenderTransform>

<RotateTransform></RotateTransform>

</XX.RenderTransform>

然后在<Template.Tragers>中定义路由事件控制，定义故事板，触发
