Interface

XAML
<Window x:Class="SystemColors1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="System.Windows.SystemColors" Height="350" Width="525">
<Window.Resources>
<DataTemplate x:Key="CellColor">
<DockPanel>
<TextBlock>
<TextBlock.Background>
<SolidColorBrush Color="{Binding Path=Color}" />
</TextBlock.Background>
<TextBlock.Text>
     
     
     
</TextBlock.Text>
</TextBlock>
</DockPanel>
</DataTemplate>
</Window.Resources>
<Grid>
<ListView Grid.Row="1"
Name="SystemColorsList"
ItemsSource="{Binding}">
<ListView.View>
<GridView AllowsColumnReorder="True">
<GridViewColumn CellTemplate="{StaticResource CellColor}"
Header="Color"
Width="Auto"/>
<GridViewColumn DisplayMemberBinding="{Binding Path=Name}"
Header="Name"
Width="Auto"/>
</GridView>
</ListView.View>
</ListView>
</Grid>
</Window>
