How show a Image in a ListviewItem when it is selected in wpf?

1. Converter Class:

public class BoolToVisibleOrHidden : IValueConverter
    {
        public BoolToVisibleOrHidden() { }
        public bool Collapse { get; set; }
        public bool Reverse { get; set; }
        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            bool bValue = (bool)value;
            if (bValue != Reverse)
            {
                return Visibility.Visible;
            }
            else
            {
                if (Collapse)
                    return Visibility.Collapsed;
                else
                    return Visibility.Hidden;
            }
        }

        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            Visibility visibility = (Visibility)value;
            if (visibility == Visibility.Visible)
                return !Reverse;
            else
                return Reverse;
        }
    }

2.  Add Reference to the xaml file:

xmlns:local="clr-namespace:Reluce.ServiceTracker.Helpers"

 <UserControl.Resources>
        <local:BoolToVisibleOrHidden x:Key="BoolToVisConverter" Collapse="True" />
        <LinearGradientBrush x:Key="LightBrush" StartPoint="0,0" EndPoint="0,1">
            <GradientBrush.GradientStops>
                <GradientStopCollection>
                    <GradientStop Color="#FFF" Offset="0.0"/>
                    <GradientStop Color="#EEE" Offset="1.0"/>
                </GradientStopCollection>
            </GradientBrush.GradientStops>
        </LinearGradientBrush>
    </UserControl.Resources>

3. Listview:

<ListView
            Name="lbMainMenu"
            Grid.Row="2"
            FontSize="17"            
            Width="209"
            Margin="2,3,0,3"           
            PreviewMouseLeftButtonUp ="lbMainMenu_PreviewMouseLeftButtonUp" >
            <ListView.Items>
                <ListViewItem Selected="Addministartion_Selected">
                    <StackPanel Name="stkPanel" Orientation="Horizontal">
                            <TextBlock
                                Name="lblScreenName"
                                Grid.Row="0"
                                Grid.Column="0"
                                Text="Administration" />
                            <Image
                                Grid.Row="0"
                                Grid.Column="1"
                                HorizontalAlignment="Right"
                                Margin="53,0,0,0"
                                Source="/Assets/arrow.png"
                                />                       
                    </StackPanel>
                </ListViewItem>

            <ListView.ItemContainerStyle>
                <Style TargetType="ListViewItem">
                    <Setter Property="Background" Value="{StaticResource LightBrush}"  />
                    <Style.Triggers>
                        <Trigger Property="IsMouseOver" Value="True">
                            <Setter Property="Cursor" Value="Hand" />
                        </Trigger>
                        <Trigger Property="IsSelected" Value="True">
                            <Setter Property="Background" Value="Green"  />
                            <Setter Property="FontWeight" Value="Bold" />
                            <Setter Property="FontStyle" Value="Italic" />
                        </Trigger>                       
                    </Style.Triggers>                   
                </Style>
            </ListView.ItemContainerStyle>
            <ListView.Background>
                <LinearGradientBrush   EndPoint="0.5,1" StartPoint="0.5,0">
                    <GradientStop Color="#666666" Offset="1"/>
                    <GradientStop Color="#999999" Offset="0.5"/>
                </LinearGradientBrush>
            </ListView.Background>
        </ListView>

4. Add Following Line Image:

Visibility="{Binding Converter={StaticResource BoolToVisConverter}, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListBoxItem}, AncestorLevel=1},Path=IsSelected}"

5. Example:

 <Image
                                Grid.Row="0"
                                Grid.Column="1"
                                HorizontalAlignment="Right"
                                Margin="127,0,0,0"
                                Source="/Assets/arrow.png"
                                Visibility="{Binding Converter={StaticResource BoolToVisConverter}, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListBoxItem}, AncestorLevel=1},Path=IsSelected}"
                            />
