显示长数据列表 [英] display long list of data

问题描述

我正在开发一个Intranet应用，该应用需要用户从一长串数据中选择大约55,000个条目.我尝试使用下拉列表，但是加载时间太长.我尝试按字母顺序将其拆分，并使用Ajax级联ddl，但达到了975个元素的限制，我不知道该如何解决.有任何想法吗?还是如何"?

解决方案

我找到了此链接，它的级联下拉列表现在可以使用. http://csharpdotnetfreak.blogspot.com/2009/02/ajax-cascading-dropdownlist- database.html [ ^ ]

我个人一次不会显示超过200个项目.没有人能一次获得仅显示200个项目的概览.我意识到您的客户可能设定了不同的要求，但他们也对逻辑论点持开放态度.

在您的情况下，我会做的是在不知道更多细节的情况下，使用弹出式窗口，用户可以在其中输入过滤器/搜索字符串，然后显示10-50个项目并使用分页.

I''m developing an intranet app that requires the user to select from a long list of data, approx 55,000 entries. I''ve tried using a dropdown list, but this takes too long to load. I tried spliting it up alphabetically and using Ajax cascading ddl, but hit a limit of 975 elements and I don''t know how to go around this. Any ideas? or "how to''s"?

解决方案

I found this link, it got cascading dropdown list to work for now. http://csharpdotnetfreak.blogspot.com/2009/02/ajax-cascading-dropdownlist-database.html[^]

Personally I''ll not show more than 200 items at a time. No person can get an overview of just 200 items being displayed at once. I realize that your customer may have set different requirements, but they''re also open to logical arguments.

What I would do in your case, without knowing more specifics, would be to use a popup where an user can input a filter/search string and then show 10-50 items and use paging.
