推荐答案

嗨

问题不清楚.

在Edit_Home_Page_Content.aspx上，您将编写用于检索数据的代码?您将必须使用查询字符串将id传递到此页面，然后必须编写代码以检索数据或将生成的Datatable保留在会话对象中并使用选定的标签进行查询.

就像

Hi

Question is not clear.

On Edit_Home_Page_Content.aspx you will be writing code for retrieving data ? you will have to pass id using query string to this page and then will have to write code to retrieve data or keep generated Datatable in session object and query it using selected label .

like

hp.NavigateUrl = "Edit_Home_Page_Content.aspx?=" + lb.Text;

并在Edit_Home_Page_Content.aspx
上

and on Edit_Home_Page_Content.aspx

use dt.select()

检索所需行的方法.

已添加代码标签-LOSMAC [/EDIT]

method to retrive desired row.
