对于我的WPF工具包的DataGrid我用下面的自定义列标题样式：WPF工具包的DataGrid：如何获得ColumnHeader宽度是相同的GridColumn宽度
<Style x:Name="ColumnStyle" x:Key="ColumnHeaderStyle" TargetType="my:DataGridColumnHeader">
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate>
<StackPanel Orientation="Vertical" HorizontalAlignment="Stretch" Background="LightYellow">
<TextBlock Text="{Binding Name}" HorizontalAlignment="Stretch" TextAlignment="Left" Background="LightGreen" />
<TextBlock Text="{Binding Data}" HorizontalAlignment="Stretch" TextAlignment="Right" Background="LightBlue" />
</StackPanel>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
头的DataContext的是代码和名称设置和数据串属性显示使用正确的数据网格的这样的初始宽度：
---------------
|Name |
| Data|
---------------
然而，当我调整列，标题显示不回流，而是保持相同：
--------------------
|Name |
| Data |
--------------------
在那里，我也希望看起来像这样：
--------------------
|Name |
| Data|
--------------------
什么我需要做的就是上述所需的行为？
类似地，标题内容似乎也不在垂直方向拉伸。
更新： 添加
<Setter Property="VerticalAlignment">
<Setter.Value>Bottom</Setter.Value>
</Setter>
的风格似乎正确对齐头底部。不幸的是，将HorizontalAlignment属性设置为'Stretch'似乎不符合我的要求。
Repro的详细信息： 下面是说明行为的代码片段。
Window1.xaml：
<Window x:Class="GridTest.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<TextBlock DockPanel.Dock="Left" Text="{Binding Name}" />
<TextBlock DockPanel.Dock="Right" Text="{Binding Data}" />

</DataTemplate>
</Setter.Value>
</Setter>
</Style>
<Style x:Name="RowHeaderStyle" x:Key="RowHeaderStyle" TargetType="my:DataGridRowHeader">
<Setter Property="Content" Value="{Binding}" />
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Path=Content.Name, RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type my:DataGridRowHeader}}}"

<TextBlock Padding="5">|</TextBlock>
<TextBlock Text="{Binding Path=Content.Data, RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type my:DataGridRowHeader}}}"

</StackPanel>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>

<Grid>
<my:DataGrid Name="dg"
ColumnHeaderStyle="{StaticResource ColumnHeaderStyle}"
RowHeaderStyle="{StaticResource RowHeaderStyle}"
HeadersVisibility="All">
</my:DataGrid>
</Grid>
</Window>
和Window1.xaml代码隐藏。CS
using System;
using System.Collections.Generic;
using System.Windows;
using System.Windows.Data;
using Microsoft.Windows.Controls;
using SLModel;
namespace GridTest
{
/// <summary>
/// Interaction logic for Window1.xaml
/// </summary>
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
this.Loaded += new RoutedEventHandler(Window1_Loaded);
}
void Window1_Loaded(object sender, RoutedEventArgs e)
{
Inputs = new List<Input>();
Outputs = new List<Output>();
Input i1 = new Input() { Name = "I 1", Data = "data 1" };
Input i2 = new Input() { Name = "I 2", Data = "data 2" };
Input i3 = new Input() { Name = "I 3", Data = "data 3" };
Inputs.Add(i1); Inputs.Add(i2);
Output o1 = new Output() { Name = "O 1", Data = "data 1" };
Output o2 = new Output() { Name = "O 2", Data = "data 2" };
Output o3 = new Output() { Name = "O 3", Data = "data 3" };
Outputs.Add(o1); Outputs.Add(o2); Outputs.Add(o3);
Relationship r1 = new Relationship() { Formula = "F1" };
Relationship r2 = new Relationship() { Formula = "F2" };
Relationship r3 = new Relationship() { Formula = "F3" };
Relationship r4 = new Relationship() { Formula = "F4" };
Relationship r5 = new Relationship() { Formula = "F5" };
Relationship r6 = new Relationship() { Formula = "F6" };
i1.Relationships.Add(r1);
i1.Relationships.Add(r2);
i2.Relationships.Add(r3);
i2.Relationships.Add(r4);
i3.Relationships.Add(r5);
i3.Relationships.Add(r6);
CreateColumn(o1, 0);
CreateColumn(o2, 1);
CreateColumn(o3, 2);
dg.Items.Add(i1);
dg.Items.Add(i2);
dg.Items.Add(i3);
dg.ColumnWidth = DataGridLength.SizeToHeader;
}
private void CreateColumn(Output output, int index)
{
Binding textBinding = new Binding();
textBinding.Path = new PropertyPath(string.Format("Relationships[{0}].Formula", index));
textBinding.Mode = BindingMode.TwoWay;
DataGridTextColumn tc = new DataGridTextColumn();
tc.Binding = textBinding;
dg.Columns.Add(tc);
tc.Header = output;
}
private List<Output> Outputs { get; set; }
private List<Input> Inputs { get; set; }
}
}
随着简单的类输入，输出，和关系为这样：
公共类输入 { 公共输入（） { 关系=新的ObservableCollection（）; }
public string Name { get; set; }
public string Data { get; set; }
public ObservableCollection<Relationship> Relationships { get; set; }
}
公共类输出 { 公共输出（）{}
public string Name { get; set; }
public string Data { get; set; }
}
公共类关系 { 公共关系（）{} public string Formula {get;组; } }
摄制步骤：
启动应用程序
观察列标题 'O 1数据1'， 'O 2数据2'，和 'O 3data 3'
通过将列分隔符向右拖动，使第一列变宽
观察到'Name'TextBlock（在这种情况下为'O 1'）和'Data'TextBlock（'data 1'）没有改变，即'Data'TextBlock没有'停靠'到列标题的右边缘。
@Phillip，我想你还需要更改'ControlTemplate'。请参阅我的答案更新。 – devuxer 2010-01-28 02:11:10
它看起来像是为行标题抓取了控件模板。我会找到一个列标题，并使用您的指示将验证我认为是正确的解决方案。 为什么扩展面板不是我默认的默认值？ – 2010-01-28 05:21:12
哦，你说得对。对不起，关于它。它看起来像列标题使用一个网格，而不是一个StackPanel。请参阅我的最新更新。 – devuxer 2010-01-28 06:25:41
