Question

我正在使用silvelight列表框控件，我坚持了。每个列表框项包含另一个列表框项现在当我绑定我的数据第二个列表框控件时，它出现水平滚动条，这不是问题我可以删除它。当我将新项目添加到第二个列表框时，如何将其高度自动增加？

对于第二个列表框，Height = Auto不起作用，因为它的滚动。

可能吗？

这是XAML代码：

   <DataTemplate x:Key="VesselListItem">
    <Border  Height="Auto" HorizontalAlignment="Left" Margin="0"  Name="border1" VerticalAlignment="Top" Width="271" CornerRadius="7" BorderThickness="2">
        <Grid  Name="grid1" Width="Auto">
            <TextBlock Height="23" HorizontalAlignment="Left" Margin="6,1,0,0" Name="textBlock1" Text="BOSPOROTUES PIRATES"  VerticalAlignment="Top" FontWeight="Normal" FontSize="14" Width="197" Foreground="#FFF9DD06" >
                    <TextBlock.Effect>
            <DropShadowEffect ShadowDepth="2" BlurRadius="2" Direction="338"/>
        </TextBlock.Effect>
            </TextBlock>
            <Rectangle Canvas.ZIndex="-1"  Height="Auto" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"  Margin="0,0,0,0" Name="rectangle1" Stroke="Black" StrokeThickness="2" Width="Auto" RadiusX="7" RadiusY="7" Opacity="0.15" Fill="White" />

尝试设置ListBox的“MaxHeight”属性。然后你的ListBox高度应相应调整，直到达到MaxHeight，然后会出现滚动条。

Silverlight ListBox高度自动增加
