GridView使用方法总结一.docx

今天到csdn发现一篇让我忍不住要转的文章，虽然作者写的都是基础，但是对于初学者来说帮助还是很大的，原文件作者是：的清清月儿她的主页 /21aspnet/。 看了文章我感觉特别不错，但是也发现了一些问题，首先是代码没有放到代码标记里，看起来不是很好看，还有一些代码没有注释新手看起来会很不方便，所以我想给他规范化一下，赵哥昨天才讲过博客的版面美观于否是很重要的，让大家看着方便，也算是为刚加入的微软社区精英计划出把力吧，为了保留作者的权力，我没有改动代码的实现 方法，只是把代码规范化了一下下，呵呵，在这里再次感谢作者清清月儿 快速预览：GridView无代码分页排序GridView选中，编辑，取消，删除GridView正反双向排序GridView和下拉菜单DropDownList结合GridView和CheckBox结合鼠标移到GridView某一行时改变该行的背景色方法一鼠标移到GridView某一行时改变该行的背景色方法二GridView实现删除时弹出确认对话框GridView实现自动编号GridView实现自定义时间货币等字符串格式GridView实现用“.”代替超长字符串GridView一般换行与强制换行GridView显示隐藏某一列GridView弹出新页面/弹出新窗口GridView固定表头(不用javascript只用CSS，2行代码，很好用)GridView合并表头多重表头无错完美版（以合并3列3行举例）GridView突出显示某一单元格（例如金额低于多少，分数不及格等）GridView加入自动求和求平均值小计GridView数据导入Excel/Excel数据读入GridView1.GridView无代码分页排序：1.AllowSorting设为True，aspx代码中是AllowSorting=True；2.默认1页10条，如果要修改每页条数，修改PageSize即可，在aspx代码中是PageSize=12。3.默认的是单向排序的，右击GridView弹出“属性”，选择AllowSorting为True即可。2.GridView选中，编辑，取消，删除：后台代码：你可以使用sqlhelper,本文没用。代码如下：代码

6.鼠标移到GridView某一行时改变该行的背景色方法一：做法：双击GridView的OnRowDataBound事件；在后台的GridView1_RowDataBound()方法添加代码，最后代码如下所示：代码 protectedvoidGridView1_RowDataBound(objectsender,GridViewRowEventArgse)inti;/执行循环，保证每条数据都可以更新for(i=0;iGridView1.Rows.Count;i+)/首先判断是否是数据行if(e.Row.RowType=DataControlRowType.DataRow)/当鼠标停留时更改背景色e.Row.Attributes.Add(onmouseover,c=this.style.backgroundColor;this.style.backgroundColor=#00A9FF);/当鼠标移开时还原背景色e.Row.Attributes.Add(onmouseout,this.style.backgroundColor=c);前台代码：代码
