我有一个包含TabControl的TreeListControl。我正在寻找TreeListControl将永远占据整个Tab区域的方法，即使由于应用程序大小的变化而导致Tab大小的变化，等等，我该如何做呢？(不幸的是，我没有看到任何等同于WinForms‘Dock.Fill的东西)
<dxdo:DockLayoutManager FloatingMode="Desktop" ClosedPanelsBarVisibility="Never">
<dxdo:LayoutGroup Orientation="Horizontal">
<dxdo:LayoutPanel x:Name="Navigation" Caption="Navigation" AllowClose="False" ItemWidth="200">
<dx:DXTabControl>
<dx:DXTabItem Header="Tasks">
<Grid Background="Transparent">
<dxg:TreeListControl AutoGenerateColumns="AddNew" EnableSmartColumnsGeneration="True" HorizontalAlignment="Left" Margin="10,10,0,0" VerticalAlignment="Top" Height="254" Width="151">
<dxg:TreeListControl.View>
<dxg:TreeListView AllowPerPixelScrolling="True" ShowTotalSummary="True" Height="291" Margin="-17,-19,-24.4,-19.2" VerticalAlignment="Bottom" />
</dxg:TreeListControl.View>
</dxg:TreeListControl>
</Grid>
</dx:DXTabItem>
<dx:DXTabItem Header="Blocks">
<Grid Background="Transparent"/>
</dx:DXTabItem>
<dx:DXTabItem Header="Functions"/>
</dx:DXTabControl>
</dxdo:LayoutPanel>
<dxdo:DocumentGroup x:Name="Documents" DestroyOnClosingChildren="False" ClosingBehavior="HideToClosedPanelsCollection"
dxmvvm:UIRegion.Region="{x:Static common:Regions.Documents}">
<dxdo:DocumentGroup.ItemStyle>
<Style TargetType="{x:Type dxdo:LayoutPanel}">
<Setter Property="Caption" Value="{Binding Caption}"/>
<Setter Property="IsActive" Value="{Binding IsActive, Mode=TwoWay}"/>
</Style>
</dxdo:DocumentGroup.ItemStyle>
</dxdo:DocumentGroup>
</dxdo:LayoutGroup>
</dxdo:DockLayoutManager>我想尝试一下这些建议，但在第74行pos 7中偶然发现了运行时错误，特别是在这段中--在最后一行之前。不知道为什么..。下面是完整的代码(关闭UserControl标记的最后一行由于某种原因没有显示在这里：

如果您检查这个Xaml：
<TabControl>
<TabItem Header="Tasks">
<Border Background="Blue" />
</TabItem>
</TabControl>您可以看到，TabItem内容将占据整个区域。
在你的情况下，设置
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"不要设置Height="254“和Width="151”的TreeListControl。
