Display treeviewitem as grid rows in wpf
提问by makambi
Basically in need to achieve something like this using treeview control in wpf: (random picture)
基本上需要使用 wpf 中的树视图控件来实现这样的东西：（随机图片）
(source: msdn.com)
（来源：msdn.com）
Where nodes and child nodes have same headers.
其中节点和子节点具有相同的标头。
I googled a lot, but my knowledge in wpf not that good.
我用谷歌搜索了很多，但我在 wpf 方面的知识并不是那么好。
Here is my parent node class:
这是我的父节点类：
public class Parent : PropertyChangedBase
{
public string ParentName { get; set; }
public BindableCollection<Child> Children { get; set; }
}
And child:
还有孩子：
public class Child : PropertyChangedBase
{
public string ChildName { get; set; }
}
My xaml tree view:
我的 xaml 树视图：
<TreeView Grid.Row="0" Grid.Column="0" ItemsSource="{Binding Nodes}">
<TreeView.Resources>
<HierarchicalDataTemplate DataType="{x:Type projectModels:Parent}" ItemsSource="{Binding Children}">
<StackPanel>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="20"></ColumnDefinition>
<ColumnDefinition Width="Auto"></ColumnDefinition>
<ColumnDefinition></ColumnDefinition>
</Grid.ColumnDefinitions>
<CheckBox Grid.Column="2"></CheckBox>
<TextBlock Grid.Column="1" Text="{Binding ParentName}">
</TextBlock>
</Grid>
</StackPanel>
</HierarchicalDataTemplate>
<DataTemplate DataType="{x:Type projectModels:Child}">
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding ChildName}"></TextBlock>
</StackPanel>
</DataTemplate>
</TreeView.Resources>
</TreeView>
I tried using Gridbut obviously it create different grids, so I can relay on column width.
我尝试使用Grid但显然它创建了不同的网格，所以我可以中继列宽。
I tried How to make gridview a child element of a treeview in wpf application, but they use ListView. It's not an option for me right now, as treeviewitem selection functionality is tightly coupled with my treeview and code behind.
我试过如何使 gridview 成为 wpf 应用程序中树视图的子元素，但他们使用ListView. 这不是我现在的选择，因为 treeviewitem 选择功能与我的 treeview 和代码紧密耦合。
Any ideas how it can be done? Thanks.
任何想法如何做到？谢谢。

<TreeView x:Name="treeviewList" ItemsSource="{Binding ManufacturerList}">
<TreeView.ItemTemplate>
<DataTemplate>
<TreeViewItem ItemsSource="{Binding Models}">
<TreeViewItem.Header>

<Grid.ColumnDefinitions>
<ColumnDefinition Width="100"></ColumnDefinition>
<ColumnDefinition Width="Auto" MinWidth="50"></ColumnDefinition>

If the only problem with your code is that each treeview item renders with different grid column widths, you can try the "share size scope" feature to align them all. In the TreeView control, set Grid.IsSharedSizeScopeto true:-
如果您的代码唯一的问题是每个树视图项以不同的网格列宽呈现，您可以尝试使用“共享大小范围”功能将它们全部对齐。在 TreeView 控件中，设置Grid.IsSharedSizeScope为 true：-
Then add a SharedSizeGroupto the ColumnDefinitions that should have the same width across all the treeview items (your first column definition has a fixed width anyway, so it's not needed on that):-
然后将 a 添加SharedSizeGroup到ColumnDefinition所有树视图项中应该具有相同宽度的s （无论如何，您的第一个列定义具有固定宽度，因此不需要）：-
<Grid.ColumnDefinitions>
<ColumnDefinition Width="20" />
<ColumnDefinition Width="Auto" SharedSizeGroup="A" />
<ColumnDefinition SharedSizeGroup="B" />
</Grid.ColumnDefinitions>
The values are just strings used to "name" the columns, and can be anything you like.
这些值只是用于“命名”列的字符串，可以是您喜欢的任何内容。
