            <datagridtextcolumn header="RowNumber" binding="{Binding Path=RowNumber}" />
        </datagrid>
    </grid>
</window>

代码落后

Code behind

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using System.Data;

namespace WpfApplication1
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

            DataTable Collection = new DataTable();
            DataRow dr = null;
            Collection.Columns.Add(new DataColumn("RowNumber", typeof(string)));
            dr = Collection.NewRow();
            dr["RowNumber"] = "test";
            Collection.Rows.Add(dr);
            dataGrid1.ItemsSource = Collection.AsDataView();
        }
    }
}

这里错了

提前致谢

推荐答案

错字？你有一个>在第一行结尾...

Typo ?? you have a ">" at the end of first line ...

<window x:class="WpfApplication1.MainWindow" xmlns:x="#unknown">
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
