listbox design issue - wpf

Question

i am trying to design some nice listbox, but every time i click on the item in the listbox
a selection background is ruined everything...
how can i make it irrelevant ?
this is the XAML:
<!-- Site List View -->
<ListBox Grid.Row="1" Name="SiteListBox" ItemsSource="{Binding}" HorizontalContentAlignment="Stretch">
<ListBox.Background>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="White" Offset="0" />
<GradientStop Color="Gainsboro" Offset="0.805" />
</LinearGradientBrush>
</ListBox.Background>
<ListBox.ItemContainerStyle>
<Style>
<Setter Property="Control.Padding" Value="0"></Setter>
<Style.Triggers>
<Trigger Property="ListBoxItem.IsSelected" Value="True">
<Setter Property="ListBoxItem.Background" Value="DarkRed" />
</Trigger>
</Style.Triggers>
</Style>
</ListBox.ItemContainerStyle>
<ListBox.ItemTemplate>
<DataTemplate>
<Border Margin="5" BorderThickness="1" BorderBrush="SteelBlue" CornerRadius="4"
Background="{Binding Path=Background, RelativeSource={
RelativeSource
Mode=FindAncestor,
AncestorType={x:Type ListBoxItem}
}}">
<TextBlock Margin="5" Text="{Binding Path=Name}" />
</Border>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
a also attached a print screen.

You can change the default colors for when a ListBoxItem container IsSelected. Set them to Transparent to get the effect that you're after
<ListBox ...>
<ListBox.Resources>
<!-- Brush for selected item that doesn't have focus -->
<SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent" />
<!-- Brush for selected item that has focus -->
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent"/>
</ListBox.Resources>
<!-- ... -->
</ListBox>
