Windows Phone 7按钮状态

Question

我们如何设置按钮的不同状态，特别是按下状态。我知道我们可以使用表情混合来设置它，但我仍然无法做到。 另外，我们可以编辑自定义按钮的按下状态吗？

感谢

正如你提到的，只是有Expression Blend中生成继承样式的副本给你，然后你可以修改状态。

现在，您可以通过修改不同的VisualState故事板来更改布局。如果你对如何做到这一点有更详细的问题，那就问问题而不是元问题！

<Style x:Key="CustomButtonStyle" TargetType="Button"> 
    <Setter Property="Background" Value="Transparent"/> 
    <Setter Property="BorderBrush" Value="{StaticResource PhoneForegroundBrush}"/> 
    <Setter Property="Foreground" Value="{StaticResource PhoneForegroundBrush}"/> 
    <Setter Property="BorderThickness" Value="{StaticResource PhoneBorderThickness}"/> 
    <Setter Property="FontFamily" Value="{StaticResource PhoneFontFamilySemiBold}"/> 
    <Setter Property="FontSize" Value="{StaticResource PhoneFontSizeMediumLarge}"/> 
    <Setter Property="Padding" Value="10,3,10,5"/> 
    <Setter Property="Template"> 
     <Setter.Value> 
      <ControlTemplate TargetType="Button"> 
       <Grid Background="Transparent"> 
        <VisualStateManager.VisualStateGroups> 
         <VisualStateGroup x:Name="CommonStates"> 
          <VisualState x:Name="Normal"/> 
          <VisualState x:Name="MouseOver"/> 
          <VisualState x:Name="Pressed"> 
           <Storyboard> 
            <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Foreground" Storyboard.TargetName="ContentContainer"> 
             <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneBackgroundBrush}"/> 
            </ObjectAnimationUsingKeyFrames> 
            <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Background" Storyboard.TargetName="ButtonBackground"> 
             <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneForegroundBrush}"/> 
            </ObjectAnimationUsingKeyFrames> 
            <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="BorderBrush" Storyboard.TargetName="ButtonBackground"> 
             <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneForegroundBrush}"/> 
            </ObjectAnimationUsingKeyFrames> 
           </Storyboard> 
          </VisualState> 
          <VisualState x:Name="Disabled"> 
           <Storyboard> 
            <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Foreground" Storyboard.TargetName="ContentContainer"> 
             <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneDisabledBrush}"/> 
            </ObjectAnimationUsingKeyFrames> 
            <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="BorderBrush" Storyboard.TargetName="ButtonBackground"> 
             <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneDisabledBrush}"/> 
            </ObjectAnimationUsingKeyFrames> 
            <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Background" Storyboard.TargetName="ButtonBackground"> 
             <DiscreteObjectKeyFrame KeyTime="0" Value="Transparent"/> 
            </ObjectAnimationUsingKeyFrames> 
           </Storyboard> 
          </VisualState> 
         </VisualStateGroup> 
        </VisualStateManager.VisualStateGroups> 
        <Border x:Name="ButtonBackground" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" CornerRadius="0" Margin="{StaticResource PhoneTouchTargetOverhang}"> 
         <ContentControl x:Name="ContentContainer" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" Foreground="{TemplateBinding Foreground}" HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}" Padding="{TemplateBinding Padding}" VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}"/> 
        </Border> 
       </Grid> 
      </ControlTemplate> 
     </Setter.Value> 
    </Setter> 
</Style> 

更新

准确地说，你需要改变追问的VisualState，就是这一部分：

<VisualState x:Name="Pressed"> 
    <Storyboard> 
     <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Foreground" Storyboard.TargetName="ContentContainer"> 
      <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneBackgroundBrush}"/> 
     </ObjectAnimationUsingKeyFrames> 
     <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Background" Storyboard.TargetName="ButtonBackground"> 
      <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneForegroundBrush}"/> 
     </ObjectAnimationUsingKeyFrames> 
     <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="BorderBrush" Storyboard.TargetName="ButtonBackground"> 
      <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneForegroundBrush}"/> 
     </ObjectAnimationUsingKeyFrames> 
    </Storyboard> 
</VisualState> 

的Storyboard.TargetProperty设置你想改变属性，即。 Foreground,Background或BorderBrush

DiscreteObjectKeyFrame设置值（如果不需要动画，则忽略keytime）。

在这里，我已经将字体颜色更改为白色，将背景更改为橙色，将borderbrush更改为紫色。

<VisualState x:Name="Pressed"> 
    <Storyboard> 
     <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Foreground" Storyboard.TargetName="ContentContainer"> 
      <DiscreteObjectKeyFrame KeyTime="0" Value="Orange"/> 
     </ObjectAnimationUsingKeyFrames> 
     <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Background" Storyboard.TargetName="ButtonBackground"> 
      <DiscreteObjectKeyFrame KeyTime="0" Value="White"/> 
     </ObjectAnimationUsingKeyFrames> 
     <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="BorderBrush" Storyboard.TargetName="ButtonBackground"> 
      <DiscreteObjectKeyFrame KeyTime="0" Value="Purple"/> 
     </ObjectAnimationUsingKeyFrames> 
    </Storyboard> 
</VisualState>
