这代表了整个页面大小的50%。

为什么要这样做,为什么这么久?我可以做些什么吗?这对移动用户来说很糟糕。

5 个答案:

答案 0 :(得分:6)

无论如何,此视图状态是什么以及如何减小其大小

在Asp.net WebForms中,每个控件都保存其状态,因为HTTP协议是无状态的,而Asp.net WebForms页面通过在此Base 64编码的字符串中保存每个控件的状态来绕过它。这是Asp.net框架知道某个控件的值是否已更改的唯一方法。但是......这自动意味着没有POST回服务器的静态控件(例如label)不需要保存它们的状态。您始终可以设置EnableViewState="false"

不幸的是,如果没有对其他控件进行任何其他代码更改就无法设置,这些控件会返回POST(每个服务器端控件都会在HTML中呈现某种输入)。这基本上意味着在页面级别(EnableViewState="false"指令内)设置@Page会产生后果,这些后果被视为控件失去其值,控件不会触发某些事件等。

因此,您获得的服务器端控件越多,它就越大(不会在某些控件上关闭它)。

但我不担心它的大小是否为10k。那将是相当快速和无痛的来回。当它变得更大时你会遇到问题。我曾经在一个项目上工作,我们遇到了某个页面的问题(由经验不足的开发人员完成),其中视图状态增长超过1MB。设想。真是个减速!

如何在页面级别完全关闭

当您在页面级别关闭视图状态时,您必须知道每次页面重新发布时,必须重新加载页面事件中加载的某些控件(或更好的数据绑定)。服务器。否则,当您的页面返回客户端时,它们将显示为空。

答案 1 :(得分:3)

您的服务器控件正在使用回发时需要的数据填充ViewState。如果您的页面没有回发,则可以禁用该页面的ViewState。

要禁用页面的ViewState,只需将EnableViewState="false"添加到@Page指令即可。请注意,如果您100%确定页面没有回发,那么您应该只将其用作解决方案。

您也可以查看此MSDN article以更好地了解ViewState的功能。

禁用静态控件的viewstate,例如gridview。 查看this question了解详情:

答案 3 :(得分:2)

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。看一下这篇文章,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。 An Analysis of Keeping ViewState out of the Page

答案 4 :(得分:1)

这篇文章过去对我说得很清楚:Taking a Bite Out of ASP.NET ViewState

默认情况下,viewstate基本上处于打开状态,并且根据您使用的控件,它可能会非常快速地失控。特别是像gridview这样的数据控件负责大量注入视图状态。您可以通过将EnableViewState属性设置为false来基于每个控件禁用它。但是要小心,因为取出viewstate也可能会取出控件的功能。所以一个接一个地进行测试测试。

另一种方式,也可能更适合移动,是使用ASP.NET MVC而不必处理自动视图状态注入。
