这个视图状态到底是什么以及如何减少其大小
在 Asp.net WebForms 中，每个控件都会保存其状态，因为 HTTP 协议是无状态的，而 Asp.net WebForms 页面通过将每个控件的状态保存在此 Base 64 编码字符串中来绕过该协议。这是Asp.net框架知道某个控件的值是否改变的唯一方法。但是...这自动意味着不会发布回服务器的静态控件（例如标签）不需要保存其状态。您始终可以设置其
EnableViewState="false"。不幸的是，如果不对其他控件进行任何其他代码更改，则无法设置此设置，这些控件确实会被 POST 回来（每个以 HTML 形式呈现某种输入的服务器端控件）。这基本上意味着在页面级别（在
@Page指令内）设置EnableViewState="false"会产生控件丢失其值、控件不触发某些事件的后果因此，您拥有的服务器端控件越多，它就会变得越大（无需在某些控件上关闭它）。
但如果它的大小是 10k 我不会担心。这会来回相当快且无痛。当它变得更大时，你就会遇到问题。我曾经参与过一个项目，我们遇到了某个页面（由经验不足的开发人员完成）的问题，其中视图状态增长了超过 1MB。想象一下。多么缓慢啊！
如何在页面级别完全关闭它
当您在页面级别关闭视图状态时，您必须意识到在页面事件中加载（或者更好地说数据绑定）的某些控件每次都必须重新加载您的页面将被发布回服务器。否则，当您的页面返回给客户端时，它们将显示为空。
What is this view state anyway and how to mitigate its size
In Asp.net WebForms every control saves its state because HTTP protocol is stateless and Asp.net WebForms pages bypass that by saving every control's state in this Base 64 encoded string. This is the only way for Asp.net framework to know whether some control's value has changed or not. But... This automatically means that static controls that don't get POSTed back to server (like label for instance) don't need to save their state. You can always set their
EnableViewState="false".Unfortunately this can't be set without any other code changes on other controls, that do get POSTed back (every server-side control that renders some sort of an input in HTML). This basically means that setting
EnableViewState="false"on page level (within@Pagedirective) will have consequences that are seen as controls loosing their values, controls not firing certain events etc.So, the more server-side controls you have the larger it will get (without turning it off on certain controls).
But I wouldn't worry if its size is 10k. That will go back and forth rather fast and painless. You will have problems when it gets much larger. I once worked on a project and we had an issue with a certain page (done by less experienced developer) where view state grew over 1MB. Imagine that. What a slowdown!
How to turn it off completely on page level
When you turn view state off on page level you have to be aware that certain controls that were loaded (or better said data bound) in on of your page's events, will have to be reloaded each time your page gets POSTed back at server. Otherwise they will show up as empty when your page gets back to the client.
您的服务器控件正在用回发时所需的数据填充 ViewState。如果您的页面没有回发，您可以禁用页面的 ViewState。
要禁用页面的 ViewState，只需将
EnableViewState="false"添加到@Page指令即可。请注意，只有当您 100% 确定页面不会回发时，才应使用此解决方案。您可能还需要查看这篇 MSDN 文章以获得更好的信息了解 ViewState 的作用。
Your server controls are filling the ViewState with data they will need on postback. If your page does not postback you can just disable the ViewState for the page.
To disable ViewState for the page you can just add
EnableViewState="false"to the@Pagedirective. Please be aware you should only use this as a solution if you are 100% sure the page does not postback.You also might want to check this MSDN article to get a better idea of what the ViewState does.
禁用静态控件的视图状态，例如网格视图。
查看此问题了解更多信息信息：
Disable viewstate for static controls, like a gridview.
Check out this question for more info:
如果您担心客户端的视图状态，请考虑将其存储在服务器端。也许在会话变量中。看看这篇文章，因为有统计比较。下载解决方案并查看如何将其存储在服务器端。
将 ViewState 排除在页面之外的分析
If you are concerned about the viewstate on the client side, then think about storing it on the server side. Perhaps in a session variable. Take a look at this article as there is statistical comparison given. Download the solution and check out how to store it on the server side.
An Analysis of Keeping ViewState out of the Page
这篇文章过去向我解释过：咬一口ASP.NET 视图状态。
基本上，视图状态默认处于打开状态，并且根据您使用的控件，它可能很快就会失控。特别是像 gridview 这样的数据控件负责大量视图状态的注入。您可以通过将 EnableViewState 属性设置为 false，在每个控件的基础上禁用该功能。但要小心，因为删除视图状态也可能会删除控件的功能。就这样一一做，测试测试测试。
另一种可能更适合移动设备的方法是使用 ASP.NET MVC，它不必处理自动视图状态注入。
This article explained it neatly to me in the past: Taking a Bite Out of ASP.NET ViewState.
Basically viewstate's on by default and, depending on which controls you use, it can get out of hand pretty fast. Especially data controls like the gridview are responsible for massive injection of viewstate. You can disable that on a per control basis by setting the EnableViewState property to false. Be careful however as taking out viewstate might also take out functionality of the controls. So do it one by one and test test test.
Another way, and likely better for mobile, is to make use of ASP.NET MVC instead which doesn't have to deal with automatic viewstate injection.
