LoadingRow WPF的列标题

Question

我怎样才能为我的装载行添加标题。我的datagrid看起来像这样：

我想在第一张支票，第二张支票等上面加上一个标题。

使用Datagrid_LoadingRow创建第一列。这是代码：

void datagrid_LoadingRow(object sender, DataGridRowEventArgs e)
{

    if (counter.CheckCount > 1)
    {
        if ((e.Row.GetIndex() + 1) == 1)
            CheckNumber = "1st";
        else if ((e.Row.GetIndex() + 1) == 2)
            CheckNumber = "2nd";
        else if ((e.Row.GetIndex() + 1) == 3)
            CheckNumber = "3rd";
        else
            CheckNumber = (e.Row.GetIndex() + 1).ToString() + "th";
        e.Row.Header = CheckNumber + " Check";
    }
    else
    {
        e.Row.Header = (e.Row.GetIndex() + 1).ToString()  + " Check";
    }
}

这是我的数据网格XAML。 May列使用ItemSource代码。

<DataGrid Name="datagrid" LoadingRow="datagrid_LoadingRow"  SelectionMode="Single" Margin="12,140,32,0" Height="310" VerticalAlignment="Top"  Width="746"
            BorderBrush="#FF444444" BorderThickness="1"  RowHeight="30" IsEnabled="True" IsReadOnly="True" FontSize="12" ColumnWidth="*"  FontFamily="Arial"
            HorizontalAlignment="Center" AutoGeneratingColumn="dgCheckSummary_AutoGeneratingColumn">
    <DataGrid.ColumnHeaderStyle>
        <Style TargetType="{x:Type DataGridColumnHeader}">
            <Setter Property="Background" Value="{StaticResource DataGridHeaderBackgroundBrush}" />
            <Setter Property="FontSize" Value="13" />
            <Setter Property="Padding" Value="5" />
            <Setter Property="Foreground" Value="White" />
            <Setter Property="HorizontalAlignment" Value="Stretch" />
            <Setter Property="HorizontalContentAlignment" Value="Center" />
        </Style>
    </DataGrid.ColumnHeaderStyle>
</DataGrid>

我想让我的行索引所在的列的标题与列Type，Amount，Edit和delete的标题相同。谁能帮我吗？我正在使用c＃wpf。非常感谢你。

如果可能，任何人都可以告诉我如何将行索引专门放在第1列中的列中？非常感谢。

这里有一个完整的示例，说明如何在不使用Loading Row事件

的情况下实现类似的行为

<强> XAML

 <Window x:Class="WpfApplication5.MainWindow"
            xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication5"
            Title="MainWindow"
            Width="525"
            Height="350">
        <Window.Resources>
            <local:ConvertItemToIndex x:Key="IndexConverter"/>
        </Window.Resources>
        <Grid>
            <DataGrid Name="DG1" ItemsSource="{Binding}" CanUserAddRows="False" CanUserDeleteRows="False"  AutoGenerateColumns="True">

                <!--Bind the Content property of the RowHeaderStyle to the Converter to create numbered rows-->
                <DataGrid.RowHeaderStyle>
                    <Style TargetType="{x:Type DataGridRowHeader}">
                        <Setter Property="Content" Value="{Binding Converter={StaticResource IndexConverter}}" />
                    </Style>
                </DataGrid.RowHeaderStyle>
            </DataGrid>


        </Grid>
    </Window>

using System;
using System.Collections.ObjectModel;
using System.Windows;
using System.Windows.Data;

namespace WpfApplication5
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        ObservableCollection<MyData> Datas = new ObservableCollection<MyData>();
        public MainWindow()
        {
            InitializeComponent();
            for (int i = 0; i < 100; i++)
            {
                Datas.Add(new MyData() { Prop1 = "test prop" + i, Prop2 = "test prop" + i, });

            }
            this.DataContext = Datas;  
        }
    }
    public class MyData
    {

        public string Prop1 { get; set; }
        public string Prop2 { get; set; }


    }
    public class ConvertItemToIndex : IValueConverter
    {
        private static int checkNumber; 
        #region IValueConverter Members
        //Convert the Item to an Index
        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            try
            {                
                return  "Check " + ++checkNumber; 

            }
            catch (Exception e)
            {
                throw new NotImplementedException(e.Message);
            }
        }
        //One way binding, so ConvertBack is not implemented
        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            throw new NotImplementedException();
        }

        #endregion
    }

}

**Result**
