    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Drop and Drag" Height="800" Width="800">
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition/>            <ColumnDefinition/>        </Grid.ColumnDefinitions>
        <DockPanel Name="_dockPanel" DataContext="{DynamicResource photos}" Background="Blue"   Width="160" Uid="5" AllowDrop="True" HorizontalAlignment="Left" Margin="0,0,0,22">            
            
            <ListBox x:Name="pictureBox" ItemsSource="{Binding}" ScrollViewer.HorizontalScrollBarVisibility="Disabled" ScrollViewer.IsDeferredScrollingEnabled="True"   >
                <ListBox.Resources>                    <Style TargetType="{x:Type ListBoxItem}">                        <!--<Setter Property="Width" Value="100"/>-->                                                <EventSetter Event="MouseLeftButtonDown" Handler="DragImage"/>                    </Style>                </ListBox.Resources>
