代码

protected void NianDaiGridView_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
//获得编号这个编号要在GridView中设置一下属性 DataKeyNames 这里设置的是数据库的主键ID
//e.RowIndex 这个通过事件源 e 来获得RowIndex 代表行号
int agentId = int.Parse(this.NianDaiGridView.DataKeys[e.RowIndex].Value.ToString());

// 这里是取得编辑时的值
// 通过 Rows[e.RowIndex] 当时事件的行
// FindControl[""]代表获取GridView内的控件名称，如FindControl("txtshehui")
// 我们取出来的控件的类型都是Control类型的,所以,我们要根据我们定义的控件类型去转换,这里是TextBox类型 (注意括号的加法)
//如果是其它类型,就转换成其它的类型就可以了如DropDownList
TextBox txtguoming = (TextBox)NianDaiGridView.Rows[e.RowIndex].FindControl("txtguoming");
TextBox txtqizhi = (TextBox)NianDaiGridView.Rows[e.RowIndex].FindControl("txtqizhi");
string guoming = txtguoming.Text;
string qizhi = txtqizhi.Text;
//调用修改的方法

//实例化对象
txpj.Model.*** model = new txpj.Model.***();
model.niandaid = agentId;
model.guoming = guoming;
model.qizhi = qizhi;
txpj.BLL.***bll = new txpj.BLL.***();
bll.Update(model);

Page.ClientScript.RegisterStartupScript(this.GetType(), "PopupScript", "alert('修改成功！')", true);

//修改完全后,把EditIndex设置为-1 ,非编辑状态
this.NianDaiGridView.EditIndex = -1;

//记得要重新调用一下绑定数据的方法哦
dataBind();
