WPF重写了ListView的ItemsPanel，改用WrapPanel做容器。不能自动换行问题

直接上正确代码：

 <ListView x:Name="lv_product" HorizontalContentAlignment="Stretch" ItemsSource="{Binding Products}" 
           ScrollViewer.HorizontalScrollBarVisibility="Disabled" ScrollViewer.VerticalScrollBarVisibility="Visible" 
           BorderBrush="Transparent" Background="Transparent">
     
     <ListView.ItemsPanel>
         <ItemsPanelTemplate>
         <WrapPanel Orientation="Horizontal" FlowDirection="LeftToRight" ></WrapPanel>
         </ItemsPanelTemplate>
     </ListView.ItemsPanel>
     <ListView.ItemTemplate>
         <DataTemplate>
             <StackPanel>
                 <Image Source="{Binding PicturePath}" Width="80" Height="80"/>
                 <TextBlock Text="{Binding ProductName}" HorizontalAlignment="Center"/>
             </StackPanel>
         </DataTemplate>
     </ListView.ItemTemplate>
 </ListView>

注意上面的 ScrollViewer.HorizontalScrollBarVisibility="Disabled"  这个设置很关键。因为ListView自带横向和纵向滚动条，必须关了自带的滚动条后WrapPanel的滚动才会起作用。
