ListView中命令行按钮应用;

1, 获取当前行的行号:  int index = ((ListViewDataItem)e.Item).DisplayIndex;

2,获取当前行的主键:  int id = Convert.ToInt32(ListView1.DataKeys[index].value);

 protected void ListView1_ItemCommand(object sender, ListViewCommandEventArgs e)
        {
            //获取当前行号;
            int index = ((ListViewDataItem)e.Item).DisplayIndex;
            //获取当前行号的主键;
            int id = Convert.ToInt32(ListView1.DataKeys[index].Value);

            if (e.CommandName == "IncSeqNo") //在Aspx页中添加一个按钮,CommandName为IncSeqNo
            {
                //获取DataSet
                T_FirendLinkTableAdapter adapter = new T_FirendLinkTableAdapter();
                //更新字段;
                adapter.UpdateQuery(id);
                //重新绑定;
                ListView1.DataBind();
            }
        }
