Question

正如问题所示，我无法让滚动条显示在我的listView中。使用网格替换StackPanel有效，但问题是我在选项卡控件中的两个列表视图然后堆叠在彼此的顶部和我拥有的标签上。建议？

List<T>

将StackPanel（s）替换成Grid个RowDefinitons：

<TabControl VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Margin="20,0,0,0" Background="#FF89BBF7">
    <TabItem Header="Active Calls">
        <TabItem.Background>
            <LinearGradientBrush EndPoint="0,1" StartPoint="0,0">
                <GradientStop Color="#FFF3F3F3" Offset="0"/>
                <GradientStop Color="#FFEBEBEB" Offset="0.5"/>
                <GradientStop Color="#FFDDDDDD" Offset="0.5"/>
                <GradientStop Color="#FF89BBF7" Offset="1"/>
            </LinearGradientBrush>
        </TabItem.Background>
        <Grid Background="#FF89BBF7" HorizontalAlignment="Stretch">
            <Grid.RowDefinitions>
                <RowDefinition Height="*" />
                <RowDefinition Height="Auto" />
                <RowDefinition Height="*" />
            </Grid.RowDefinitions>
            <ListView Name="lvwCalls"  HorizontalAlignment="Stretch" VerticalAlignment="Top" Height="Auto" Margin="10,10,10,40" >
                <ListView.View>

ScrollViewers和StackPanels不能很好地协同工作：
