Silverlight 按钮点击效果

Question

我需要将点击效果应用到silverlight Button，即当你点击按钮时它应该有点击填充。期望什么机制。

它应该像实际的按钮点击一样，点击它应该下降，释放应该再次上升

例如：堆栈溢出时保存编辑按钮

首先，您需要为您的按钮创建一个样式 - 在您的 xaml 的资源部分中。

查看此示例样式

<Style x:Key="MyButtonStyle"  x:Name="MyButtonStyle" TargetType="Button">
  <Setter Property="Background" Value="#FF1F3B53"/>
  <Setter Property="Foreground" Value="#FF000000"/>
  <Setter Property="Padding" Value="3"/>
  <Setter Property="BorderThickness" Value="1"/>
  <Setter Property="BorderBrush">
      <Setter.Value>
          <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
              <GradientStop Color="#FFA3AEB9" Offset="0"/>
              <GradientStop Color="#FF8399A9" Offset="0.375"/>
              <GradientStop Color="#FF718597" Offset="0.375"/>
              <GradientStop Color="#FF617584" Offset="1"/>
          </LinearGradientBrush>
      </Setter.Value>
  </Setter>
  <Setter Property="Template">

你说你想要一个“点击填充”，所以根据需要编辑“按下”按钮状态。

然后，您可以通过将样式分配给您的按钮来使用该样式 - 通过设置按钮样式属性：Style="{StaticResource MyButtonStyle}"
