Wpf 列标题样式

您好，我在尝试创建样式并将其应用于DataGrid标头时遇到了以下问题：出现以下错误

DependencyProperty.UnsetValue}不是属性“ColumnHeaderStyle”的有效值。"

他没有意识到这是真的，如果有人能给我一个想法，我会很感激离开网格代码和风格-

将此行中的

静态资源

替换为

动态资源

-

<Setter Property="ColumnHeaderStyle"
        Value="{StaticResource DataGridHeaderFloatingWindow}" >

到

或者，在xaml中将样式

DataGridHeaderFloatingWindow

移动到

DataGridFloatingWindow

上方，以解析引用

---

使用

DynamicResource

将在加载数据网格时在运行时解析引用。然而，对于

StaticResource

引用，需要在加载xaml时解析，因此在xaml中使用的任何

StaticResource都应该在其用法之上定义
欢迎使用Stackoverflow！这是Silverlight还是WPF？请为您的问题添加正确的标记。这可能看起来很愚蠢，但请确保引用其他资源的资源稍后在文件中声明。也就是说，如果一个资源（您的DataGrid样式）使用另一个资源（您的标头样式），请确保首先在XAML文件中声明标题样式。谢谢你说得对，移动已解决的样式标题声明谢谢你说得对，移动已解决的样式标题声明，这也证明了DynamicSource在不遵守顺序的情况下声明样式似乎更好
