我有一个按钮的基本样式:
<Style x:Key="ButtonStyle_base" TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Grid Name="grid" Margin="0,0,0,0">
<Rectangle Name="rectangle" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" >
<Rectangle.Effect>
<DropShadowEffect BlurRadius="3" Opacity="0.4" ShadowDepth="6"/>
</Rectangle.Effect>
</Rectangle>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsFocused" Value="True" />
<Trigger Property="IsDefaulted" Value="True" />
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
所以,在网格中我有一个矩形。为了让我的应用程序可换肤,我在另一个资源字典中添加了一个基于此的样式:
<Style x:Key="ButtonStyle" BasedOn="{StaticResource ButtonStyle_base}">
<Setter Property="Rectangle.Fill" >
<Setter.Value>
<LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1" >
<GradientStop Color="#FFFFFFFF" Offset="0.5" />
<GradientStop Color="#CCFFFFDD" Offset="1" />
</LinearGradientBrush>
</Setter.Value>
</Setter>
</Style>
我想要的是改变矩形的填充。它不起作用。我怎样才能做到这一点?

将填充与Background
的{{1}}属性绑定,
Button
从派生的样式
设置背景<Style x:Key="ButtonStyle_base" TargetType="{x:Type Button}">
