Windows Phone 7按鈕狀態

Question

我們如何設置按鈕的不同狀態，特別是按下狀態。我知道我們可以使用表情混合來設置它，但我仍然無法做到。 另外，我們可以編輯自定義按鈕的按下狀態嗎？

感謝

正如你提到的，只是有Expression Blend中生成繼承樣式的副本給你，然後你可以修改狀態。

現在，您可以通過修改不同的VisualState故事板來更改佈局。如果你對如何做到這一點有更詳細的問題，那就問問題而不是元問題！

<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">

            <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}">

        </Border> 
       </Grid> 
      </ControlTemplate> 
     </Setter.Value> 
    </Setter> 
</Style> 

更新

準確地說，你需要改變追問的VisualState，就是這一部分：

<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設置你想改變屬性，即。 Foreground,Background或BorderBrush

DiscreteObjectKeyFrame設置值（如果不需要動畫，則忽略keytime）。

在這裏，我已經將字體顏色更改爲白色，將背景更改爲橙色，將borderbrush更改爲紫色。

<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>
