c# 一个问题,DATAGRIDVIEW重些时碰到的错误,请高手指点

using System;
using System.ComponentModel;
using System.Collections.Generic;
using System.Diagnostics;
using System.Text;
using System.Windows.Forms;
using System.Data.SqlClient;
using System.Data;
using System.Drawing;

namespace CHANCE
{
    public partial class CsDataGridView : DataGridView
    {
        public CsDataGridView()
        {
            InitializeComponent();
        }
        public CsDataGridView(IContainer container)
        {
            container.Add(this);

            InitializeComponent();
        }
        #region FillAll
        public void FillAll()
        {
            System.Data.SqlClient.SqlConnection cn;
            cn = new SqlConnection("Data Source=192.168.10.20;Initial Catalog=Northwind;User ID=sa");
            cn.Open();
            string sql;
            sql = "Select * from Products";
            System.Data.SqlClient.SqlDataAdapter da = new SqlDataAdapter(sql, cn);
            //DataTable dt = new DataTable(); ;
            DataSet dt = new DataSet();
            da.Fill(dt);
            //this.VirtualMode = true;
            this.DataSource = dt.Tables[0];
            cn.Close();
        }
        #endregion

    }
}

这是重写--

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace TestGDGV_CSharp
{
    public partial class Form2 : Form
    {
        public Form2()
        {
            InitializeComponent();
        }

        private void Form2_Load(object sender, EventArgs e)
        {


            this.csDataGridView1.FillAll();

        }



        private void csDataGridView1_RowsRemoved(object sender, DataGridViewRowsRemovedEventArgs e)
        {
            MessageBox.Show("ppp");
        }


    }
}

再引用控件后,使用FILLALL填充数据,怎么触发了RowsRemoved?请指示. --------------------编程问答-------------------- 我想用this.csDataGridView1.Update()可以吗?

高手继续回答!! --------------------编程问答-------------------- this.csDataGridView1.FillAll();
-----这是重写里的一个方法,目的是填充数据,this.csDataGridView1.Update()  这可能达不到目的吧 --------------------编程问答-------------------- 不行吧 --------------------编程问答--------------------

  =这答案！ --------------------编程问答-------------------- MS不可以吧

补充：.NET技术 ,  C#
