11.单独页面编辑

  • ListView的在位编辑只适合字段比较少、比较简单的场合,复杂数据的编辑、插入、查看等要在单独页面中才可
  • 创建一个单独的页面Edit***.aspx,然后在ListView页面中的编辑模板中放一个编辑的超连接,向Edit***.aspx传递?id=1&action=edit.页面顶端增加一个Edit***.aspx?action=addnew的超连接。
  • 使用FormView控件进行单条数据的编辑,在Page_Load中判断action,然后使用FormView1.ChangeMode方法切换FormView的模式。
  • 强类型DataSet中增加一个GetDataByID方法,在ObjectDataSource中选择这个方法为Select参数,参数源为QueryString,QueryStringField为id.
  • 在元素插入、修改完成(Inserted\Updated事件)后重定向到列表页面。

例子:

    有两个网页,一个是简单显示数据表中的记录,另一个是单独的编辑页面,在编辑或新增后重新回到第一个浏览页面。 要在数据集中加入一个GetDataByID的方法,主要用到单独页面的编辑操作(传ID)。

第一个页面:
