WPF-Listview滚动条未显示

Question

因此，正如问题所暗示的那样，我很难让滚动条显示在我的listView中。 用网格替换StackPanel是可行的，但是问题是我在选项卡控件中拥有的两个列表视图然后堆叠在彼此和我拥有的标签之上。 建议？

用带有多个RowDefinitons的Grid替换StackPanel ：

<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>
                    <GridView>
                        <GridViewColumn Header="Priority" Width="50" DisplayMemberBinding="{Binding priority}" />
                        <GridViewColumn Header="Call Status" Width="60" DisplayMemberBinding="{Binding callStatus}" />
                        <GridViewColumn Header="Call Type" Width="60" DisplayMemberBinding="{Binding callType}" />
                        <GridViewColumn Header="Dispatched Persons" Width="120" DisplayMemberBinding="{Binding dispatchedPersons}" />
                        <GridViewColumn Header="Region" Width="50" DisplayMemberBinding="{Binding region}" />
                        <GridViewColumn Header="Location" Width="80" DisplayMemberBinding="{Binding location}"/>
                        <GridViewColumn Header="Specific Location" Width="100" DisplayMemberBinding="{Binding specLocation}" />
                        <GridViewColumn Header="Time" Width="50" DisplayMemberBinding="{Binding time}" />
                        <GridViewColumn Header="Dispatch #" Width="60" DisplayMemberBinding="{Binding dispatchNumber}" />
                        <GridViewColumn Header="Address" Width="60" DisplayMemberBinding="{Binding address}" />
                    </GridView>
                </ListView.View>
            </ListView>
            <Label Content="Pending Calls:" Grid.Row="1"/>
            <ListView HorizontalAlignment="Stretch" VerticalAlignment="Top" Height="Auto" Margin="10,10,10,50" Grid.Row="2">
                <ListView.View>
                    <GridView>
                        <GridViewColumn Header="Priority" Width="120" DisplayMemberBinding="{Binding Priority}" />
                        <GridViewColumn Header="Call Type" Width="120" DisplayMemberBinding="{Binding CallType}" />
                        <GridViewColumn Header="Location" Width="150" DisplayMemberBinding="{Binding Location}" />
                        <GridViewColumn Header="Specific Location" Width="100" DisplayMemberBinding="{Binding SpecLocation}" />
                        <GridViewColumn Header="Time" Width="100" DisplayMemberBinding="{Binding Time}" />
                        <GridViewColumn Header="Dispatch #" Width="100" DisplayMemberBinding="{Binding DispatchNumber}" />
                    </GridView>
                </ListView.View>
            </ListView>
        </Grid>
    </TabItem>
    <TabItem Header="History">
        <Grid Background="#FF89BBF7">
            <ListView HorizontalAlignment="Stretch" VerticalAlignment="Top" Height="Auto" Margin="10,10,10,20" >
                <ListView.View>
                    <GridView>
                        <GridViewColumn Header="Call Time" Width="70" DisplayMemberBinding="{Binding CallTime}" />
                        <GridViewColumn Header="Location" Width="80" DisplayMemberBinding="{Binding Location}" />
                        <GridViewColumn Header="Specific Location" Width="100" DisplayMemberBinding="{Binding SpecLocation}" />
                        <GridViewColumn Header="Dispatch Number" Width="120" DisplayMemberBinding="{Binding DispatchNumber}" />
                        <GridViewColumn Header="Description" Width="80" DisplayMemberBinding="{Binding Description}" />
                        <GridViewColumn Header="Report Number" Width="100" DisplayMemberBinding="{Binding ReportNumber}" />
                        <GridViewColumn Header="Group" Width="60" DisplayMemberBinding="{Binding Group}" />
                        <GridViewColumn Header="Address" Width="80" DisplayMemberBinding="{Binding Address}" />
                    </GridView>
                </ListView.View>
            </ListView>
        </Grid>
    </TabItem>
</TabControl>

ScrollViewers和StackPanels不能很好地配合使用：

StackPanel的水平滚动不起作用
