Answer 1

试试这个

使用此名称空间using System.Windows.Media;并在按钮点击事件中写下此

private void WhereToStayButton_Click(object sender, RoutedEventArgs e)
{
   stackpanelname.Background = new SolidColorBrush(Colors.Red);
}

您可以通过在Click事件触发器上应用Storyboard来实现这一点：

<ControlTemplate TargetType="HyperlinkButton">
   <StackPanel Orientation="Horizontal"  Background="#EBEBEB" x:Name="sp1">
      <Image Source="/Assets/Menu/wheretostay.png"  Stretch="None"/>
      <TextBlock />
   </StackPanel>
   <ControlTemplate.Triggers>
     <EventTrigger RoutedEvent="ButtonBase.Click">
        <BeginStoryboard>
          <Storyboard>
            <ColorAnimation To="Green" Storyboard.TargetName="sp1" 
                            Storyboard.TargetProperty="Background.Color"/>
          </Storyboard>
        </BeginStoryboard>
     </EventTrigger>
   </ControlTemplate.Triggers>
 </ControlTemplate>

对于Windows Phone 7，请使用 Visual State ：

<ControlTemplate TargetType="HyperlinkButton">
   <ControlTemplate.Resources>
     <SolidColorBrush x:Key="PhoneBackgrounBrush" Color="Green"/>
   </ControlTemplate.Resources>
   <StackPanel Orientation="Horizontal" x:Name="sp1">
      <VisualStateManager.VisualStateGroups>
         <VisualStateGroup x:Name="CommonStates">
            <VisualState x:Name="Normal"/>
            <VisualState x:Name="MouseOver"/>
            <VisualState x:Name="Pressed">
               <Storyboard>
                 <ObjectAnimationUsingKeyFrames
                         Storyboard.TargetProperty="Background"
                         Storyboard.TargetName="sp1">
                    <DiscreteObjectKeyFrame KeyTime="0"
                            Value="{StaticResource PhoneBackgrounBrush}"/>
                 </ObjectAnimationUsingKeyFrames>
               </Storyboard>
            </VisualState>
         </VisualStateGroup>
       </VisualStateManager.VisualStateGroups>
       <Image Source="/Assets/Menu/wheretostay.png" Stretch="None"/>
       <TextBlock />
   </StackPanel>
 </ControlTemplate>

正如Rohit所说，利用视觉状态来达到你的要求..，

<ControlTemplate TargetType="HyperlinkButton">
    <StackPanel Orientation="Horizontal"  Background="#EBEBEB" x:Name="sp1">
          <VisualStateManager.VisualStateGroups>
                <VisualStateGroup x:Name="CommonStates">
                <VisualState x:Name="Normal"/>
                <VisualState x:Name="MouseOver"/>
                <VisualState x:Name="Pressed">
                     <Storyboard>
                              <ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(Panel.Background).(SolidColorBrush.Color)" Storyboard.TargetName="sp1">
                        <EasingColorKeyFrame KeyTime="0" Value="#FFE91818"/>
                                    </ColorAnimationUsingKeyFrames>
                     </Storyboard>
                </VisualState>
                <VisualState x:Name="Disabled"/>
            </VisualStateGroup>
         </VisualStateManager.VisualStateGroups>
       <Image Source="/Assets/Menu/wheretostay.png"  Stretch="None"/>
       <TextBlock />
   </StackPanel>
</ControlTemplate>
