Question

在此gridview中仅更新更新行（仅复选框列）的最便捷方法是什么？什么是检查行更新的方便方法？

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; }

    }

                <asp:BoundField DataField="name" />

            </Columns>
        </asp:GridView>
    </div>

您可以使用GridView.RowUpdating活动.....

<asp:GridView ID="GridView1" AutoGenerateColumns="false" runat="server" OnRowUpdating="TaskGridView_RowUpdating">

在代码背后，

 protected void TaskGridView_RowUpdating(object sender, GridViewUpdateEventArgs e)
  {    
    //logic code here
  }

如何只更新gridview中更新的行？
