In XAML style, how to change solid background to gradient?
提问by Edward Tanguay
I've got a MainResources.xaml file in which I have a style that defines how each of my windows in my application look:
我有一个 MainResources.xaml 文件，其中的样式定义了我的应用程序中的每个窗口的外观：
<Style x:Key="MainBorderStyle" TargetType="{x:Type Border}">
<Setter Property="Background" Value="WhiteSmoke" />
<Setter Property="BorderBrush" Value="LightGray" />
<Setter Property="BorderThickness" Value="1" />
<Setter Property="CornerRadius" Value="5" />
<Setter Property="SnapsToDevicePixels" Value="True" />
</Style>
Instead of "WhiteSmoke" I want my background to be this gradient:
我希望我的背景是这种渐变，而不是“WhiteSmoke”：
<LinearGradientBrush>
<GradientStop Color="#ccc" Offset="0"/>
<GradientStop Color="#bbb" Offset="1"/>
</LinearGradientBrush>
But the following attempt causes VS2008 to tell me "Style setters do not support child elements":
但是以下尝试导致 VS2008 告诉我“样式设置器不支持子元素”：
<Style x:Key="MainBorderStyle" TargetType="{x:Type Border}">
<Setter Property="Background">
<LinearGradientBrush>
<GradientStop Color="#ccc" Offset="0"/>
<GradientStop Color="#bbb" Offset="1"/>
</LinearGradientBrush>
</Setter>
<Setter Property="BorderBrush" Value="LightGray" />
<Setter Property="BorderThickness" Value="1" />
<Setter Property="CornerRadius" Value="5" />
<Setter Property="SnapsToDevicePixels" Value="True" />
</Style>
What is the correct way to put a gradient color as the background for this style?
将渐变颜色作为此样式的背景的正确方法是什么？

You are missing the <Setter.Value>
你错过了 <Setter.Value>
<Style ...>
<Setter Property="...">
<Setter.Value>
<LinearGradientBrush />
</Setter.Value>
</Setter>
</Style>
