动态显示/隐藏TR的组 [英] Dynamically Show/Hide Groups of TR's

问题描述

我搜索了一段时间试图找到答案，但无济于事。


我正试图找到动态显示的最佳方式（或任何方式）隐藏

组的TR'。例如，我有一个约6个表行的部分，如果满足某个条件，则需要隐藏
。但我不想

隐藏整张桌子。并且，我不想拆分桌子，因为

列需要保持不变。


我想在每个上使用runat = server TR的，只是隐藏它们每个单独的
，但这看起来真的很邋and，我认为那里

必须是一个更好的方法来做到这一点。我真的需要一些不含HTML的

容器，它可以作为TR'的包装器，而不会渲染任何额外的HTML。


asp：PlaceHolder是完美的，因为它不会渲染任何额外的

HTML，但它在设计时不允许任何其他嵌套服务器控件

（看起来很傻）。而asp：Panel可以包装任何HTML或服务器

控件，但它呈现HTML（IE中的div和Netscape中的表 -

真的输入了HTML） 。并且< span runat = server>不喜欢嵌套的TR'。


我只需要一些包装器服务器控件，可以包含任何内容（HTML

和服务器控件），而无需在任何浏览器上呈现任何HTML。好像

这将被广泛使用（和需要）功能，但我没有太多的运气

找到这样的东西。

如有任何建议，我们将不胜感激。


提前感谢您的帮助！

解决方案

我使用PlaceHolder< tr>元素一直在。如果你使用的是asp表对象，这可能不会是
工作，但是如果你使用的话，那就不要....它是......这是不必要的开销。此外，也许它在设计视图中给你一个错误，

但是如果它......不使用设计视图，请使用HTML视图。

为什么你认为使TR runat =服务器变得草率？

runat = server是ASP.NET的基础之一。

>我使用PlaceHolder< tr>元素一直都是。


这不是< tr> PlaceHolder遇到问题的元素 -

它是我的< tr>内的服务器控件。

PlaceHolder不支持的元素。就像我说的那样，我需要一些允许

嵌入式HTML和服务器控件的东西。


感谢您的回复，但它看起来不像PlaceHolder将在这种情况下使用
。

I searched for a while trying to find the answer to this, but to no avail.

I am trying to find the best way (or any way) to dynamically show and hide
groups of TR''s. For example, I have a section of about 6 table rows that
all need to be hidden if a certain condition is met. But I don''t want to
hide the whole table. And, I don''t want to split up the table because the
columns need to remain intact.

I thought about using runat=server on each of the TR''s, and just hiding them
each individually, but that just seems really sloppy, and I thought there
had to be a better way to do it. I really need some sort of HTML-less
container that can serve as a wrapper for the TR''s without rendering any
additional HTML.

An asp:PlaceHolder would be perfect since it doesn''t render any additional
HTML, but it doesn''t allow any other nested server controls at design time
(which seems silly). And an asp:Panel can wrap around any HTML or server
controls, but it renders HTML (div in IE and table in Netscape -- which
really hoses the HTML). And a <span runat=server> doesn''t like nested TR''s.

I just need some "wrapper" server control that can contain anything (HTML
and Server controls) without rendering ANY HTML on any browser. Seems like
this would be widely used (and needed) feature, but I haven''t had much luck
finding such a thing.

Any suggestions would be appreciated.

Thanks in advance for your help!

I use the PlaceHolder around <tr> elements all the time. This might not
work if you are using an asp table object, but if you are, don''t....it''s
uncessary overhead. Also, maybe it''s giving you an error in design view,
but if it is...don''t use design view, use HTML view.

Hi,

Why do you think that make the TR runat=server is sloppy ?
runat=server is one of the bases of ASP.NET.

It''s not the <tr> elements that the PlaceHolder is having problems with --
it''s the server controls that are within my <tr> elements that the
PlaceHolder doesn''t support. Like I said, I need something that will allow
both embedded HTML _and_ server controls.

Thanks for your reply, but it doesn''t seem like a PlaceHolder is going to
work with this situation.
