How to disable View State MAC globally?

I'm tired of including EnableViewStateMac="false" in every page. How to do that globally? You can disable it on the <pages> element in the web.config , like this: <configuration> <system.web> <pages enableViewStateMac="False" /> </system.web> </configuration> The answer above explain to you how to set it in the Web.Config, but look at MSDN and you will see what it says here : This attribute should never be set to false in a production Web site, even if the application or page does not use view state. The view state MAC helps ensure the security of other ASP.NET functions in addition to view

ASP.NET: Moving ViewState to bottom of page

匆匆过客 提交于 2019-11-29 04:38:29
What are the latest and greatest ways to move ViewState to bottom of the page Can this be done in a IHttpHandler that can be specified in the web.config to intercept requests to "*.aspx"? <httpHandlers> <add verb="*" path="*.aspx" type="MyApp.OptimizedPageHandler" /> <httpHandlers> Other options is that this could be done in a IHttpModule , but that is not as performant , as it will intercept all requests. Also it could be done in an a class deriving from the Page or MasterPage -class, but this is not as modular . Are there any performance penalties to this? You can control how and where

How do I turn off viewstate for good?

问题 Coming from a PHP background I love using clean URLs to grab data from one service to another. However, on some of my ASP.NET projects I get the horrible ViewState parameter in my URLs. Is there a way to turn this off globally? What affect will this have on my ASP.NET app? 回答1: You can turn off viewstate for the whole site like this: <system.web> <pages enableViewState="false" /> That said, you shouldn't be getting it on the url. ViewState is a hidden field that is sent to the server with a

User control (ascx) and properties

问题 The only way I've found to persist property values within a user control is to use the ViewState. public string Title { get { return Convert.ToString(ViewState["Title"]); } set { ViewState["Title"] = value; } } I can't say I'm real impressed with this though, as the more properties a user control has the more crap you'll be sticking in the ViewState. Is there a better way to persist properties? 回答1: It depends. If you need to property values to be persisted beyond a post-back then you'll

Keeping ViewState in SessionPageStatePersister

我是研究僧i 提交于 2019-11-29 02:03:08
I want to keep viewstate of a specific page in session but following code block does not help me, what might I be missing? So here is the code-behind file content of my page; public partial class ConfigurationEditorWebForm : PageBase { protected void Page_Load(object sender, EventArgs e) { } protected override bool VerifyAccess() { return true; } protected override PageStatePersister PageStatePersister { get { return new SessionPageStatePersister(this); } } } Note that even after you move the page state to view state, you will still see a __Viewstate element on your pages. Also, I believe that

ViewState Chunking in asp.net

醉酒当歌 提交于 2019-11-28 23:40:46
I keep on hearing this words "Viewstate Chunking". What is Viewstate Chunking? And how it is working for ASP.NET pages? kril When the ViewState in your page becomes very large it can be a problem since some firewalls and proxies will prevent access to pages containing huge ViewState sizes. For this purpose ASP.NET introduces the ViewState Chunking mechanism. So ASP.NET enables splitting of the ViewState's single hidden field into several using the MaxPageStateFieldLength property in the web.config section. When the MaxPageStateFieldLength property is set to a positive number, the view state

ASP.NET MVC and ViewState

走远了吗. 提交于 2019-11-28 22:47:43
问题 Now I've seen some questions like this, but it's not exactly what I want to ask, so for all those screaming duplicate, I apologize :). I've barely touched ASP.NET MVC but from what I understand there is no ViewState/ControlState... fine. So my question is what is the alternative to retaining a control's state? Do we go back to old school ASP where we might simulate what ASP.NET ViewState/ControlState does by creating hidden form inputs with the control's state, or with MVC, do we just assume

Postback not working with ASP.NET Routing (Validation of viewstate MAC failed)

谁说胖子不能爱 提交于 2019-11-28 22:06:33
I'm using the ASP.NET 3.5 SP1 System.Web.Routing with classic WebForms, as described in http://chriscavanagh.wordpress.com/2008/04/25/systemwebrouting-with-webforms-sample/ All works fine , I have custom SEO urls and even the postback works. But there is a case where the postback always fails and I get a: Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster. Here is the scenario to reproduce the error: Create a standard webform

Why would you ever use asp.net's ViewState storage object over the Session storage object?

偶尔善良 提交于 2019-11-28 18:08:31
问题 Other than because session storage is session-global to more than one page, why would you ever want to use the viewstate to hold values? It seems kind of ridiculous to send any kind of information other than a few small query string like values, back and forth from the client to server. I mean what a waste of bandwidth(!), simply for storage purposes. The session, while global across multiple pages, seems like a completely superior alternative to the viewstate. Especially with asp.net ajax
