为什么在代码隐藏中将设置显示为none而不将其添加到HTML？ [英] Why does setting display to none in the code-behind not add it to the HTML?

问题描述

我想设置几个HtmlTableRows的显示样式 显示：无，在后台代码如下所示：

I'm trying to set the display style of a couple of HtmlTableRows to "display:none" in code-behind like so:

foapalrow3 = new HtmlTableRow();
foapalrow3.ID = "foapalrow3";
foapalrow3.Attributes["display"] = "none";

...但它不起作用 - 查看源代码不包含display：nonefor无论是foapalrow3还是-4。为什么不，我怎么能强迫它按预期工作呢？

...but it's not working - the "View Source" contains no "display:none" for either foapalrow3 or -4. Why not, and how can I force this to work as intended?

要么我的麻木或墙壁最终会崩溃;我已经砰像后卫成砖墙与它，因为这流的-codedness 所示。

Either my nogging or the wall is going to eventually crumble with this; I've been slamming like a fullback into a brick wall with it, as this stream-of-codedness shows.

推荐答案

显示不是HTML属性，因此会被丢弃。如果要添加CSS样式，请使用样式而不是属性，如下所示：

display is not an HTML attribute, so it is discarded. If you want to add CSS styles, use Style instead of Attributes like this:

foapalrow3.Style["display"] = "none";
foapalrow4.Style.Add("display", "none"); // alternate syntax

正如另一个答案所述，理论上你可以用<$ c完成同样的事情$ c>属性[style] ，但我个人在过去遇到过这个问题， Style 属性是首选（在我看来，优越的选择。

As the other answer states, you could theoretically accomplish the same thing with Attributes["style"], but personally I've had issues with that in the past and the Style property is the preferred (and in my opinion, superior) option.
