代碼如下:

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
        sqlcon = new SqlConnection(strCon);
        sqlcon.Open();
        string bianhao = Convert.ToString(this.GridView1.DataKeys[e.RowIndex].Value);
        string beizhu = ((TextBox)(GridView1.Rows[e.RowIndex].Cells[6].Controls[0])).Text.ToString();
        string sqlstr = "SQL語句'";
        sqlcom = new SqlCommand(sqlstr, sqlcon);
        sqlcom.ExecuteNonQuery();
        sqlcon.Close();
        GridView1.EditIndex = -1;
        bind();
    }

取列的值為原來的，并不是更新后的，原因是因為Page_Load中加載了數據，每次更新后會自動刷新，所以需在Page_Load中判斷一下是否頁面回傳，再加載，如下

復制代碼代碼如下:

 protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            bind();
        }
    }
