如何在WPF Datagrid上格式化标题？ [英] How do I format headers on a WPF Datagrid?

问题描述

我正在使用Codeplex的WPF Datagrid。

我可以在dg：DataGrid元素中对行进行样式化和以下属性。

但是，如何对标题进行风格化？我找到了100个在网页上的例子，这些例子定义了样式，并使用例如x：Key =DataGridColumnHeaderStyle在Datagrid元素，但它们似乎都不适合我。

将Datagrid头文件背景更改为橙色的DataGrid？

 < dg：DataGrid AlternatingRowBackground =＃ddd
 RowBackground =＃eee
 Name =theGrid1
 VerticalAlignment =Stretch
 AutoGenerateColumns =False
 BorderBrush =＃ddd> 
 ... 
< / dg：DataGrid> 
  

解决方案

这种情况下的样式在一个名为generic .xaml它应该在你的项目的一个themems文件夹中。

找到它并打开它。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}> 
  

基本上它在模板中的另一个位置定义：

I am using the WPF Datagrid from Codeplex.

I am able to style the rows and with the following attributes in the dg:DataGrid element.

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.

How can I just e.g. change the Datagrid Header background to orange on this DataGrid?

<dg:DataGrid AlternatingRowBackground="#ddd" 
    RowBackground="#eee" 
    Name="theGrid1" 
    VerticalAlignment="Stretch" 
    AutoGenerateColumns="False" 
    BorderBrush="#ddd">
...
</dg:DataGrid>

解决方案

The style in this case is in a file called generic.xaml it should be loacted in a themems folder in your project.

find it and open it. inside you will find this line that controls the background of the column headers

 <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
