How to make items in a DockPanel expand to fit all available space in WPF?
提问by LM.
I have a StackPanelcontaining a StackPaneland some other items. The first StackPanelhas a vertical orientation, the the inner one has a horizontal orientation. The inner one has a TreeViewand a ListView, I would like them to expand and fit the width of the window, which I set by the window and allow the user to change. I would also like the outer StackPanelto fit the height of the window. How do I do this?
我有一个StackPanel包含 aStackPanel和一些其他项目。第一个StackPanel具有垂直方向，内部具有水平方向。内部有 aTreeView和 a ListView，我希望它们扩展并适应窗口的宽度，我由窗口设置并允许用户更改。我还希望外部StackPanel适合窗户的高度。我该怎么做呢？
Edit:I've converted to using a DockPanel, and I've set the DockPanel.Dockproperties correctly in each of the elements, and have disabled LastChildFillin both of the dockpanels, the layout still does not stretch.
编辑：我已经转换为使用 a DockPanel，并且我已经DockPanel.Dock在每个元素中正确设置了属性，并且LastChildFill在两个停靠面板中都禁用了，布局仍然没有拉伸。
The Code:
编码：
<Window x:Class="Clippy.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="400" Width="600" MinHeight="400" MinWidth="600" Loaded="Window_Loaded" SizeChanged="Window_SizeChanged">
<DockPanel Name="wrapperDockPanel" LastChildFill="False">
<Menu Height="22" Name="mainMenu" Width="Auto" DockPanel.Dock="Top" />
<ToolBar Height="26" Name="mainToolBar" Width="Auto" DockPanel.Dock="Top" />
<DockPanel Height="Auto" Name="contentDockPanel" DockPanel.Dock="Top" LastChildFill="False">
<TreeView Name="categoryTreeView" />
<ListView Name="clipListView" />
</DockPanel>
<StatusBar Height="23" Name="mainStatusBar" DockPanel.Dock="Top" />
</DockPanel>
</Window>

This should do it - I set it up so that the TreeView and the ListView shared the main view 50/50; if you don't want that, set it to 'Auto' and '*' or something. Use "LastChildFill" to your advantage!
这应该可以 - 我设置它以便 TreeView 和 ListView 共享主视图 50/50；如果您不希望那样，请将其设置为“自动”和“*”之类的。使用“LastChildFill”对您有利！

<DockPanel LastChildFill="True">
<Menu Width="Auto" DockPanel.Dock="Top" />
<ToolBar Width="Auto" DockPanel.Dock="Top" />
<StatusBar DockPanel.Dock="Bottom" />
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="0.5*" />
<RowDefinition Height="0.5*" />
</Grid.RowDefinitions>
<TreeView Name="categoryTreeView" Grid.Row="0" />
<ListView Name="clipListView" Grid.Row="1" />
</Grid>
</DockPanel>
</Window>

Set width and height properties to "auto"
将宽度和高度属性设置为“自动”

Use a DockPanel instead. StackPanel explicitly doesn't care about visible space, whereas DockPanel does all of it's size calculation based on available space.
请改用 DockPanel。StackPanel 明确不关心可见空间，而 DockPanel 根据可用空间进行所有大小计算。
Update:
更新：
In addition, in my experience, putting the body of the window into a View, and only having the View in the Window makes for a better Auto Size experience.
另外，根据我的经验，将窗口主体放入一个视图中，并且只有在窗口中包含视图才能获得更好的自动调整大小体验。
For some reason putting all of the children directly into the Window seems to not auto size very well.
出于某种原因，将所有孩子直接放入 Window 似乎不能很好地自动调整大小。

I would remove the explicit DockPanel.Dock attribute from the element that you want to stretch (fill) the unused space.
我会从要拉伸（填充）未使用空间的元素中删除显式 DockPanel.Dock 属性。
