本文介绍如何解决ListBox无法滚动到底部的问题，关键在于通过将ListBox的Height属性绑定到其父容器的实际高度，确保ListBox知道自己的大小。通过在Grid中设置不同Row的高度属性，可以灵活调整各个组件的布局。示例代码展示了如何实现这一过程，包括使用DataTemplate为ListBox项设置样式。

ListBox无法滚动到底部，原因是Listbox它不知道自己有多高，所以需要添加以下代码。

注意红色部分，将LayoutRoot的实际高度与之绑定，告诉Listbox你有多高

The key to scrolling is the Height value of the ScrollViewer or ListBox (with its built-in ScrollViewer). The Height should be set to the desired viewport size on the screen. You can set Height to an explicit number, but you can have Silverlight set it to the available height on the screen. Do this by putting the ScrollViewer or ListBox in a Grid row that has Height="*".

 
           <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">  
             <Grid.RowDefinitions>  
                 <RowDefinition Height="Auto"/>  
                 <RowDefinition Height="*"/>  
             </Grid.RowDefinitions>  
             <TextBox Grid.Row="0" Height="72" HorizontalAlignment="Left" Margin="0" Name="filter" Text="search" VerticalAlignment="Top" Width="458" LostFocus="filter_LostFocus" GotFocus="filter_GotFocus" Foreground="Gray" TextChanged="filter_TextChanged" />  
             <ListBox Grid.Row="1" HorizontalAlignment="Left" Margin="0,12,0,0" Name="people" VerticalAlignment="Top">  
                 <ListBox.ItemTemplate>  
                     <DataTemplate>  
                         <TextBlock Text="{Binding BuiltName}" Style="{StaticResource PhoneTextLargeStyle}"/>  
                     </DataTemplate>  
                 </ListBox.ItemTemplate>  
             </ListBox>  
         </Grid> 
 
 

Row 0 of the grid has Height="Auto" which means its height will expand to the total height of its contents. Row 1 of the grid has Height="*" which means it will be set to the remaining available height on the screen.
