+ ylcd.ToString() + "' and jh='" + jh + "' and sjrq=to_date('" + sjrq + "','yyyy-mm-dd')";
Response.Write(sqlstr);
ora_db.NoreturnSql(sqlstr);
GridView2.EditIndex = -1;
bind();
}
GridView2.DataKeyNames是ylcd，我用Response.Write(sqlstr)显示出的ylcd、cs、jddj是没改变之前的，我是新手请多多帮助！！！谢谢！
------解决方案--------------------
点击其他的ylcd的值都不变吗？
ylcd.ToString() 改成GridView1.DataKeys[e.RowIndex].Value.ToString()
