我有一个带有图像的按钮，其中包含我创建的动画的鼠标输入触发器。问题是当单击按钮时按钮，并且鼠标输入时也不会再次出现动画。所以我认为使用Mouse Over触发器可能会解决问题，但我不知道如何解决问题。这是我的代码：
<telerik:RadButton Name="setting" CornerRadius="12" Click="settings_Click" Grid.Column="2" IsBackgroundVisible="False">
<Image Source="/CRI_12;component/Images/cog-64.png" RenderTransformOrigin=".5,.5" Stretch="Uniform">
<Image.RenderTransform>
<RotateTransform x:Name="AnimatedRotate" Angle="0" />
</Image.RenderTransform>
<Image.Triggers>
<EventTrigger RoutedEvent="Image.MouseEnter">
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetName="AnimatedRotate"
Storyboard.TargetProperty="Angle"
By="0"
To="45"
Duration="0:0:.5"
FillBehavior="Stop" />
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Image.Triggers>
</Image>
</telerik:RadButton>

在触发器之后应用RadButton的默认模板中定义的视觉状态，因此触发器将被覆盖。您需要编辑模板才能使其适用于RadButton。引用很多标记，但这里是：

这里有一些例子，不要忘记更换Telerik的按钮并更改图片来源：
<Button Height="50" Width="50">
<Image Source="Images/ok_icon.png">
<Image.RenderTransform>
<RotateTransform CenterX="25" CenterY="25"/>
</Image.RenderTransform>
<Image.Style>
<Style TargetType="Image">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation
Storyboard.TargetProperty="(Image.RenderTransform).(RotateTransform.Angle)"
From="0"
To="45"
Duration="0:0:0.5"
FillBehavior="Stop"/>
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
</Trigger>
</Style.Triggers>
</Style>
</Image.Style>
</Image>
</Button>
