我有一个datagrid，其中行可能具有颜色代码的状态或要求它们加粗的数据。我已经能够轻松地进行大胆工作了。如果它有颜色代码，我希望整个行背景以该颜色显示。我搜索了几个网站并尝试了许多不同的方法来获得行颜色编码，但它们似乎都没有工作。我错过了什么？

答案 0 :(得分：0)
在WPF中，最好只设置一次属性，否则可能会出现意外行为。我猜测为什么粗体工作和着色不是因为虽然你已经在后面的代码中设置了两个，但你也在样式中设置了背景颜色。
当您删除样式中的setter时问题是否仍然存在？
<Setter Property="Background" Value="#FFFFFF"/>
修改
您似乎无法在后面的代码中指定背景颜色，因为您尚未在模板中实现Background属性。
prop="{TemplateBinding Background}"
进一步深入研究表明，您还在代码中设置了三次背景。
要查看您的代码是否有效，您可以
替换
<Border x:Name="DGR_Border"
BorderBrush="{TemplateBinding Background}"
BorderThickness="{TemplateBinding BorderThickness}"
SnapsToDevicePixels="True">
<Border.Background>
<LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1">
<GradientStop Offset="0" Color="#AAFFFF" />
<GradientStop Offset="1" Color="#AAFFD4" />
</LinearGradientBrush>
</Border.Background>
与
<Border x:Name="DGR_Border"
BorderBrush="{TemplateBinding Background}"
BorderThickness="{TemplateBinding BorderThickness}"
SnapsToDevicePixels="True"
Background="{TemplateBinding Background}">
并注释掉你的
<!--<VisualStateManager.VisualStateGroups>
...
</VisualStateManager.VisualStateGroups>-->
。
