WPF工具包DataGrid如何设置列标题SelectionBackground？

Question

I would just like to change the background of the column headers in the datagrid to Blue with White text. I was finally able to but the Mouse Over and Selection styles for the Column Header change the background to White. As you can imagine White text on a White Background won't do.

For some reason this has been the most absurdly difficult thing to change.

I tried using Styles: (had no effect)

<Style TargetType="{x:Type xcdg:ColumnManagerCell}">
            <Setter Property="SelectionBackground" Value="Black" />
            <Setter Property="Background" Value="#475463" />
            <Setter Property="FontWeight" Value="Bold" /> 
            <Setter Property="Foreground" Value="White" />
        </Style>

I tried doing it in the Grid itself (just throws an error)

 <xcdg:DataGridControl ....
 <xcdg:ColumnManagerCell SelectionBackground="Black"></xcdg:ColumnManagerCell>

What magical incantation is required to perform the simple task of altering the hover background color on these cells???

Thanks

The issue is that the Background is not handled by the ColumnManagerCell itself but a Border inside it.

Reaching it is at best difficult so if your only concern is readability then just set the Foreground using a Trigger :

<Style TargetType="xcdg:ColumnManagerCell">
    <Setter Property="Background" Value="#475463" />
    <Setter Property="FontWeight" Value="Bold" />
    <Setter Property="Foreground" Value="White" />
    <Style.Triggers>
        <Trigger Property="IsMouseOver" Value="True">
            <Setter Property="Foreground" Value="Black"></Setter>
        </Trigger>
    </Style.Triggers>
</Style>

You could also change the whole template , it's up to you to tell if it's worth the pain...
