            e.Row.Cells[0].Text = id.ToString();//将变量id的值传给GridView控件的每一行的单元格中
        }
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            //绑定图书类型
            string bookType = e.Row.Cells[3].Text.ToString();           //获取图书类型编号
            string typeSql = "select * from tb_bookType where TypeID=" + bookType;
            SqlDataReader typeSdr = dataOperate.getRow(typeSql);
            typeSdr.Read();                                             //读取一条数据
            e.Row.Cells[3].Text = typeSdr["typeName"].ToString();       //设置图书类型
            //绑定书架
            string bookcase = e.Row.Cells[4].Text.ToString();           //获取书架编号
            string caseSql = "select * from tb_bookcase where bookcaseID=" + bookcase;
            SqlDataReader caseSdr = dataOperate.getRow(caseSql);
            caseSdr.Read();
            e.Row.Cells[4].Text = caseSdr["bookcaseName"].ToString();   //设置书架
            //设置鼠标悬停行的颜色
            e.Row.Attributes.Add("onMouseOver", "Color=this.style.backgroundColor;this.style.backgroundColor='#DAE7FC'");
            e.Row.Attributes.Add("onMouseOut", "this.style.backgroundColor=Color;");
        }
    }
}
前台用一个datagriw设置一个读取数据库的数据，当经过时或者悬停时会有变化,代码最两行就是关键代码。具体效果图如下：
