indows phone 8正常的绑定图片只显示一列（即上下一列显示），怎样把显示的图片由一列变成一行（左右一行）显示呢？求大神帮助？？？
<Grid Grid.Row="1" Name="advertGrid">   
            <ListBox Name="advertListBox">
                <ListBox.ItemTemplate>
                    <DataTemplate>
                        <Grid>
                            <Image Name="imgAdvertisement" Source="{Binding AdPic}"  Stretch="Fill" Height="112" ></Image>
                        </Grid>                                        
                    </DataTemplate>
                </ListBox.ItemTemplate>
            </ListBox>
        </Grid> 楼主真是大手笔，我就不客气了
把这个加到listbox里面，把宽度设宽点看看效果
          <ItemsControl.ItemsPanel>
                    <ItemsPanelTemplate>
                        <VirtualizingStackPanel Orientation="Horizontal" />

                    </ItemsPanelTemplate>
                </ItemsControl.ItemsPanel>
[解决办法]

          <ItemsControl.ItemsPanel>
                    <ItemsPanelTemplate>
                        <VirtualizingStackPanel Orientation="Horizontal" />
                    </ItemsPanelTemplate>
                </ItemsControl.ItemsPanel>
再加上绑定代码
