WPF remove glossy effect from selection/mouse over of a GridView

问题

I've searched an answer to this simple question but didn't find a solution yet. I have the following code:

<Grid>
    <Border BorderBrush="#666666" BorderThickness="1,1,1,1" CornerRadius="3">
        <Border.Background>
            <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                <GradientStop Color="#FF020f1e" Offset="0"/>
                <GradientStop Color="#FF484F58" Offset="1"/>
            </LinearGradientBrush>
        </Border.Background>
        <ListView Name="lvUsers" Background="Transparent" Foreground="White" Margin="3" FontSize="12" SelectionChanged="lvUsers_SelectionChanged">

            <ListView.Template>
                <ControlTemplate TargetType="{x:Type ListView}">
                    <Border CornerRadius="1" BorderThickness="1" BorderBrush="Transparent">
                        <ScrollViewer>
                            <ItemsPresenter />
                        </ScrollViewer>
                    </Border>
                </ControlTemplate>
            </ListView.Template>

            <ListView.View>
                <GridView>

                    <GridView.Columns>
                        <GridViewColumn>
                            <GridViewColumn.CellTemplate>
                                <DataTemplate>
                                    <CheckBox Tag="{Binding ID}" IsChecked="{Binding IsChecked}" Checked="CheckBox_CheckedChanged" Unchecked="CheckBox_CheckedChanged" IsHitTestVisible="False" Focusable="False"/>
                                </DataTemplate>
                            </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                        <GridViewColumn DisplayMemberBinding="{Binding ID}" Header="ID" />
                        <GridViewColumn DisplayMemberBinding="{Binding Name}" Header="Name" />
                    </GridView.Columns>
                </GridView>                  
            </ListView.View>

            <ListView.ItemContainerStyle>
                <Style TargetType="ListViewItem">
                    <EventSetter Event="PreviewMouseLeftButtonDown" Handler="ListViewItem_PreviewMouseLeftButtonDown" />

                    <Style.Triggers>
                        <Trigger Property="IsMouseOver" Value="true">
                            <Setter Property="Background" Value="Transparent"/>

                        </Trigger>
                        <Trigger Property="IsSelected"  Value="true">
                            <Setter Property="Background" Value="Transparent"/>
                            <Setter Property="BorderBrush"  Value="Black"/>
                        </Trigger>

                    </Style.Triggers>
                </Style>
            </ListView.ItemContainerStyle>
        </ListView>
    </Border>
</Grid>

that results in the following effect when I select or "mouse over" a row:

MyApplication

I want to remove that glossy effect and obtain exactly the style of a plain "ListView":

Target Application

Can you tell me the easiest way to achive this?

Thank you very much

ListViewItem has some fancy triggers in its Template (Controltemplate.Triggers) which change background under some conditions (e.g. for selected items). To remove them set a simplified Template, without triggers:

<Style TargetType="ListViewItem">
<Setter Property="Template">
    <Setter.Value>
        <ControlTemplate TargetType="{x:Type ListViewItem}">
            <Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}" 
                    BorderThickness="{TemplateBinding BorderThickness}" 
                    Background="{TemplateBinding Background}" 
                    Padding="{TemplateBinding Padding}"
                    SnapsToDevicePixels="true">
                <GridViewRowPresenter 
                    HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" 
                    SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
                    VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
            </Border>
        </ControlTemplate>
    </Setter.Value>
</Setter>
<Style.Triggers> 
<!-- your triggers for IsMouseOver and IsSelected -->
</Style.Triggers>

You are obviously using some custom style that provides this effect.

You could try to set the Style property of the ListView to {x:Null} to use the default style:

<ListView Style="{x:Null}" Name="lvUsers" Background="Transparent" Foreground="White" Margin="3" FontSize="12" SelectionChanged="lvUsers_SelectionChanged">
