【问题描述】：
在此网格视图中仅更新已更新行（仅复选框列）的最便捷方法是什么？检查行是否更新的便捷方法是什么？
c#
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
List<customer> listCustomer = new List<customer>();
customer cust1 = new customer(){name="fred",email="fred@mail.com",jobless="true"};
customer cust2 = new customer(){name="mark",email="mark@mail.com",jobless="false"};
listCustomer.Add(cust1);
listCustomer.Add(cust2);
GridView1.DataSource=listCustomer;
GridView1.DataBind();
}
}
protected void btnUpdate_Click1(object sender, EventArgs e) { foreach（GridView1.Rows 中的 GridViewRow rw） { CheckBox thiscontrol = (CheckBox)rw.Cells[0].FindControl("cb"); var ch = thiscontrol.Checked; //只更新更新的行？ } }
public class customer
{
public string name { get; set; }
public string email { get; set; }
public string jobless { get; set; }
}
