【问题描述】：

我有包含数据网格的用户控件。即使我有足够的边距并且底部有空白空间，我的状态栏也会在网格填充后消失。我做错了什么？？？？

<DockPanel VerticalAlignment="Stretch" LastChildFill="False">

    <StackPanel Orientation="Horizontal" DockPanel.Dock="Top" Margin="0,0,0,0">


        <controls:ucXXXXSummary  x:Name="ucSummary"  Margin="20,20,20,30" Height="Auto" Width="Auto"/>

     <controls:XXXXUC x:Name="ucXXXX"  Margin="20,20,20,30" Height="Auto" Width="Auto"/>
    </StackPanel>


    <StatusBar DockPanel.Dock="Bottom" Height="25">
        <StatusBarItem>
            <StatusBarItem>
                <TextBlock Name="lblStatus" Text="abc!!!!!!!!!!!"/>
            </StatusBarItem>
        </StatusBarItem>
    </StatusBar>

</DockPanel>

【解决方案1】：

不要依赖边距来相对于彼此定位元素。使用适当的Panel，例如Grid：

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="*" />
        <RowDefinition Height="*" />
        <RowDefinition Height="Auto" />
    </Grid.RowDefinitions>
    <controls:ucXXXXSummary  x:Name="ucSummary" Margin="20,20,20,30" />
    <controls:XXXXUC Grid.Row="1" x:Name="ucXXXX"  Margin="20,20,20,30" />
    <StatusBar Grid.Row="2" Height="25">
        <StatusBarItem>
            <StatusBarItem>
                <TextBlock Name="lblStatus" Text="abc!!!!!!!!!!!"/>
            </StatusBarItem>
        </StatusBarItem>
    </StatusBar>
</Grid>

StackPanels 不适合滚动内容：Horizontal scroll for stackpanel doesn't work
