How do I format headers on a WPF Datagrid?
提问by Edward Tanguay
I am using the WPF Datagrid from Codeplex.
我正在使用 Codeplex 的 WPF Datagrid。
I am able to style the rows and with the following attributes in the dg:DataGrid element.
我能够在 dg:DataGrid 元素中设置行的样式并使用以下属性。
But how do I style the Headers? I find 100s of examples on the web which define Styles and use e.g. x:Key="DataGridColumnHeaderStyle" in the Datagrid element, but none of them seem to work for me.
但是我如何设置标题的样式？我在网上找到了 100 多个定义样式并在 Datagrid 元素中使用例如 x:Key="DataGridColumnHeaderStyle" 的示例，但它们似乎都不适合我。
How can I just e.g. change the Datagrid Header background to orange on this DataGrid?
我怎样才能在这个 DataGrid 上将 Datagrid Header 背景更改为橙色？
<dg:DataGrid AlternatingRowBackground="#ddd"
RowBackground="#eee"
Name="theGrid1"
VerticalAlignment="Stretch"
AutoGenerateColumns="False"
BorderBrush="#ddd">
...
</dg:DataGrid>

The style in this case is in a file called generic.xaml it should be loacted in a themems folder in your project.
在这种情况下，样式位于名为 generic.xaml 的文件中，它应该位于项目中的 themems 文件夹中。
find it and open it. inside you will find this line that controls the background of the column headers
找到它并打开它。在里面你会发现这一行控制列标题的背景
<dg:DataGridHeaderBorder SortDirection="{TemplateBinding SortDirection}"
IsHovered="{TemplateBinding IsMouseOver}"
IsPressed="{TemplateBinding IsPressed}"
IsClickable="{TemplateBinding CanUserSort}"
Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}"
Padding ="{TemplateBinding Padding}"
SeparatorVisibility="{TemplateBinding SeparatorVisibility}"
SeparatorBrush="{TemplateBinding SeparatorBrush}">
basically its defined at another place in the template: this will explain TemlateBinding to you MSDN TemplateBinding
基本上它是在模板中的另一个地方定义的：这将向您解释 TemplateBinding MSDN TemplateBinding

There is also a property on the DataGrid that allows for styling the header:
DataGrid 上还有一个属性允许设置标题样式：
<DataGrid.ColumnHeaderStyle>
<Style TargetType="{x:Type DataGridColumnHeader}">
<Setter Property="FontWeight"
Value="Bold" />
</Style>
</DataGrid.ColumnHeaderStyle>
