我想使用样式设置网格的背景。我风格我正在设置网格的背景属性。
但我有一个填充了LinearGradientFill的边框和一个也包含LinearGradientFill的Path。
但我无法将两者结合起来。
以下是示例代码。我想把它创建成一种风格。
<Grid>
<Border BorderBrush="Black" BorderThickness="2">
<Border.Background>
<LinearGradientBrush EndPoint="1,0.5" StartPoint="0,0.5">
<GradientStop Color="Black" Offset="0.953" />
<GradientStop Color="White" Offset="0" />
</LinearGradientBrush>
</Border.Background>
</Border>
<Path Data="M 0,0 C 0,620 10,10 560,0" Height="60" VerticalAlignment="Top">
<Path.Fill>
<LinearGradientBrush EndPoint="1,0.5" StartPoint="0,0.5">
<GradientStop Color="Black" Offset="0" />
<GradientStop Color="White" Offset="0.779" />
</LinearGradientBrush>
</Path.Fill>
</Path>
</Grid>
它给我一个错误:
属性'价值'设置不止一次。

阿奇,
您需要使用模板才能将任意XAML放入样式中。不幸的是,只有控件有模板,而网格和边框不是控件。但有一个解决方案。虽然不如您所希望的那样干净,但以下XAMl应该可以实现您的目标。您将以下XAML粘贴到Charles Petzold's XAML Cruncher中以查看结果:
<UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Width="400" Height="400">
<UserControl.Resources>
<!-- A ContentControl template that defines your background -->
<ControlTemplate x:Key="BackgroundTemplate" TargetType="ContentControl">
<Grid>
<Border BorderBrush="Black" BorderThickness="2">
<Border.Background>
<LinearGradientBrush EndPoint="1,0.5" StartPoint="0,0.5">
<GradientStop Color="Black" Offset="0.953" />
<GradientStop Color="White" Offset="0" />
</LinearGradientBrush>
</Border.Background>
</Border>
<Path Data="M 0,0 C 0,620 10,10 560,0" Height="60" VerticalAlignment="Top">
<Path.Fill>
<LinearGradientBrush EndPoint="1,0.5" StartPoint="0,0.5">
<GradientStop Color="Black" Offset="0" />
<GradientStop Color="White" Offset="0.779" />
</LinearGradientBrush>
</Path.Fill>
</Path>
</Grid>
</ControlTemplate>
<!-- A ContentControl Style that references the background template -->
<Style x:Key="BackgroundStyle" TargetType="ContentControl">
<Setter Property="Template" Value="{StaticResource BackgroundTemplate}" />
</Style>
</UserControl.Resources>
<!-- Typical usage; place the background ContentControl behind your body content -->
<Grid x:Name="LayoutRoot">
<ContentControl Style="{StaticResource BackgroundStyle}" />
<TextBlock Text="Your Content" Foreground="Red" FontSize="36" HorizontalAlignment="Center" VerticalAlignment="Center" />
</Grid>
</UserControl>
