更改绑定到DataGridView的DataTable中的列顺序不会反映在视图中

DataGridView 一定会有 DataTable . 稍后,我将更多列添加到 数据表 数据表格控件 . 而是将列附加到最初生成的集合上。

这个例子说明,,

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    public DataTable data = new DataTable();

    private void button1_Click(object sender, EventArgs e)
    {

        this.dataGridView1.DataSource = data;
        for (int i = 0; i < 5; i++)
        {
            this.data.Columns.Add(i.ToString());
        }
    }

    private void button2_Click(object sender, EventArgs e)
    {
        DataColumn foo = new DataColumn();
        this.data.Columns.Add(foo);
        foo.SetOrdinal(0);
    }

    private void button3_Click(object sender, EventArgs e)
    {
        foreach (DataColumn tmpCol in this.data.Columns)
        {
            Console.WriteLine("{0} : {1}", tmpCol.ColumnName, tmpCol.Ordinal);
        }
    }
}

数据表 .
