WPF Wie Kopfzeilenfarbe von gridview ändern

Question

Ich habe versucht zu lernen, wie Sie eine ListView anpassen, die eine GridView enthält.

Ich war in der Lage, herauszufinden und zu lernen jedes Teil, das ich brauche ... außer einem.

Wie ändere ich die Farbe jener weißen Linien zwischen jedem Kopfspaltennamen?

XAML:

<Window x:Class="UITest.MainWindow" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
     xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
     xmlns:local="clr-namespace:UITest" 
     mc:Ignorable="d" 
     Title="MainWindow" Height="200" Width="400"> 
    <StackPanel> 
     <ListView Margin="0 50 0 0" Name="lvUsers" BorderBrush="{x:Null}" BorderThickness="0" Background="Red" Padding="0"> 
      <ListView.View> 
       <GridView> 
        <GridView.ColumnHeaderContainerStyle> 
         <Style TargetType="{x:Type GridViewColumnHeader}"> 
          <Setter Property="Background" Value="DarkBlue"></Setter> 
          <Setter Property="Foreground" Value="White"></Setter> 
          <Setter Property="BorderBrush" Value="{x:Null}"></Setter> 
          <Setter Property="BorderThickness" Value="0"></Setter> 
          <Setter Property="Margin" Value="0"></Setter> 
          <Setter Property="Padding" Value="0"></Setter> 
         </Style> 
        </GridView.ColumnHeaderContainerStyle> 
        <GridViewColumn Header="Name" Width="120" DisplayMemberBinding="{Binding Name}" /> 
        <GridViewColumn Header="Age" Width="50" DisplayMemberBinding="{Binding Age}" /> 
        <GridViewColumn Header="Mail" Width="150" DisplayMemberBinding="{Binding Mail}" /> 
       </GridView> 
      </ListView.View> 
      <ListView.ItemContainerStyle> 
       <Style TargetType="ListViewItem"> 
        <Setter Property="Background" Value="Blue"></Setter> 
        <Setter Property="Foreground" Value="White"></Setter> 
       </Style> 
      </ListView.ItemContainerStyle> 
     </ListView> 
    </StackPanel> 
</Window> 

Und hier ist der .CS Code:

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 
using System.Windows; 
using System.Windows.Controls; 
using System.Windows.Data; 
using System.Windows.Documents; 
using System.Windows.Input; 
using System.Windows.Media; 
using System.Windows.Media.Imaging; 
using System.Windows.Navigation; 
using System.Windows.Shapes; 

namespace UITest 
{ 
    public partial class MainWindow : Window 
    { 
     public MainWindow() 
     { 
      InitializeComponent(); 
      List<User> items = new List<User>(); 
      items.Add(new User() { Name = "John Doe", Age = 42, Mail = "john@doe-family.com" }); 
      items.Add(new User() { Name = "Jane Doe", Age = 39, Mail = "jane@doe-family.com" }); 
      items.Add(new User() { Name = "Sammy Doe", Age = 7, Mail = "sammy.doe@gmail.com" }); 
      lvUsers.ItemsSource = items; 
     } 

     public class User 
     { 
      public string Name { get; set; } 

      public int Age { get; set; } 

      public string Mail { get; set; } 

     } 
    } 
}

Dies ist, wie ich es in meiner Anwendung getan ...

<Style TargetType="{x:Type GridViewColumnHeader}"> 
    <Setter Property="Template"> 
     <Setter.Value> 
      <ControlTemplate TargetType="{x:Type GridViewColumnHeader}"> 
       <Border BorderThickness="0,0,0,1" BorderBrush="White" Background="Transparent"> 
        <TextBlock x:Name="ContentHeader" Text="{TemplateBinding Content}" Padding="5,5,5,0" Width="{TemplateBinding Width}" TextAlignment="Center" /> 
       </Border> 
      </ControlTemplate> 
     </Setter.Value> 
    </Setter> 
    <Setter Property="OverridesDefaultStyle" Value="True" /> 
    <Setter Property="Foreground" Value="White" /> 
</Style> 

Sehen Sie, wenn diese hilft.
