This is happening in multiple versions of Safari, including 5.xIt will post _EVENTTARGET=&_EVENTARGUMENT= but nothing for __VIEWSTATE=This is only happening in Safari, and only on one page of our site.I can't reproduce it - we've spent days trying to. The viewstate isnt overly huge on this page.
View 2 RepliesCompletely disabling viewstate
View 6 RepliesI have a site that features some pages which do not require any post-back functionality. They simply display static HTML and don't even have any associated code. However, since the Master Page has a <form runat="server"> tag which wraps all ContentPlaceHolders, the resulting HTML always contains the ViewState field, i.e:
<input
type="hidden"
id="__VIEWSTATE"
value="/wEPDwUKMjEwNDQyMTMxM2Rk0XhpfvawD3g+fsmZqmeRoPnb9kI="
/>
EDIT: I tried both variants of setting EnableViewState on page level with no luck at all:
<%@ Page Language="C#" EnableViewState="false" %>
<%@ Page Language="C#" EnableViewState="true" %>
I realize, that when decrypted, this value of the input field corresponds to the <form> tag which I cannot remove because it is on my master page. However, I would still like to remove the ViewState field for pages that only display static HTML. Is it possible?
I have an application where ViewState is set to "true". In some pages, I can see the viewstate value at the top of the page (just below the addressbar). But this only happens in Safari browser. And when this is shown, clicking on any button in that page, it is going to some error page. In Mozilla, IE7/8, Opera it is running properly !
View 3 RepliesI have a shopping cart page (Cart.aspx) that has a button that will (sometimes) post to a third party payment gateway, if payment is necessary. The payment gateway will process the payment and then do a silent post to my website (Order.aspx) so I can update the order status.
Order.aspx always throws an invalid viewstate error, even though viewstate is disabled on the page.
What's happening is that Cart.aspx (which has viewstate enabled) posts to the payment gateway, and the gateway will post it back as part of the silent post. Even though Order.aspx has viewstate disabled and validation disabled, it still tries to validate the __viewstate field it's being given.
I know setting EnableViewState=false will disable the rendering of the __viewstate field, but if another page provides the field, shouldn't it still skip validation? I tried calling ViewState.Clear() on the Page_Init event of Order.aspx, but ViewState is apparently empty. how to get around this? I don't want to disable ViewState on Cart.aspx (in some cases it may be necessary), but I can't figure out how to clear it on Order.aspx.
I want to access the data from datatable object. When i trying to get the fieldslist usng "Field" method. But I could not find the method with my table object. Eventhoguh i forcibly write a method and trying to access the fields, It is giving the below error for the first join in query. Rest of the lines are fine.
What is the reason behind it.
The errro: "Error 2 'LINQ2DB.SP_VS_OP' does not contain a definition for 'Field' and the best extension method overload 'System.Data.DataRowExtensions.Field<T>(System.Data.DataRow, string)' has some invalid arguments"
What is the meaningof the error. Shall i do any other changes in the query line?
var QueryChnl = from oSPOP in SPOP.AsEnumerable()
join oDiscChannel in DiscChannel.AsEnumerable() on oSPOP.Field<int>("spid") equals oDiscChannel.Field<int>("SPID")
join oChannel in Channel.AsEnumerable() on oDiscChannel.Field<int>("channel") equals oChannel.Field<int>("channelID")
where oSPOP.Mappingkey == 3200004
select new { oSPOP.Mappingkey, oChannel.channel, oDiscChannel.STATUS };
What is the difference when using ::
Hidden field vs View state??
when to use each one ??
which one more secure?? and which is better than in performance?
what are the alternatives?
I have selected the tables using the wizard, but for some reason CR doesn't display all the fields in the tables, so there are some tables in Field Explorer that lack some fields. The fields that aren't shown are both int, and varchar, some of them allow nulls and some of them don't, I can't seem to find a pattern as why some fields aren't loaded into Field Explorer.

View 1 RepliesI have a GridView that shows results according to user selections above it via checkboxes, dropdown lists etc. Once user clicks on a hyperlink value on one of the rows in GridView, user is taken to another page which is sort of a drill down for that line item in the GridView.
Everything works fine so far, except when the user hits the back button, user selections that filter data on the Gridview page are lost. So, I added ViewState="True" on these filter options (i.e. checkbox, dropdownlist etc.). When back button is hit selections were still cleared. How could I remedy this?
i am facing the following problem while saving the viewstate on the server side using the savepagestatetopersistencemedium, but this is not working for the pages which contains update panel.
View 2 RepliesNow here is the weird thing. First i am running it locally on the built in vs2008 web server.I load my control in fine, do a postback from a linkbutton, locally on my machine it all works fine, no issue.However when it goes onto my host, it falls over with the message:
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request.Now i also load controls dynamically and use postbacks and things in the admin area of the site...and that works fine, however my front end just keeps failing? See the code behing below:

when the page is not Posted back, I saved all values in the viewstate.
I have been getting this error a lot lately with some of my users, and I had a couple of concerns with view state and I have read so many articles but I am still lost..
1. I use masterpage on all the pages and I need viewstate for some of the pages but..
There is a page where a user will fill out the information and then submit this data to a cgi server, and it is where I get most of the Client Disconnected errors, what would happen if I disable viewstate when they click on that button?
Now when a user browses from one page to another, does the view state from the previous page get deleted? If not how would I delete it?
Does the master page have its own viewstate? Would I be able to make sure none of items on my master page are using the viewstate?
i have a big query and many data
when i try to execute this query i got this error
how can i run this query complete?
I am trying to make a UserControl that have all data process, initialize data, ajax, all self contain into one control.So I can insert to anywhere on my Asp pages.But the problem is, the UserControl contains a Script Manager and the Page that contain that User Control has a Script Manager too, so Asp doesn't allow me to have two Script Manager in one page.In case like this, I wonder if UserControl can completely self contain?Or the proper way of using UserControl is just using it like a template, and all the data process, event handler I have to do on the page that contains the UserControl?

I am a .NET web designer and I wish to create a modular based website for people, similar to what DNN does (but I want to create my own cut down version).
The idea is that I create a base website that can 'activate' features which the client needs (and has paid for). These features may be used by many clients which require frequent future updates for all clients (so I wish to keep upgrade time down to a minimum).
For example, I upload the base web application using web deploy and it sets up the core database tables/views/SPs in the process.Then I login into the website as developer and activate the out of the box features that I wish to permit the user to take advantage of. The only way I can think of currently is via user control, resources etc..But I need a little of your experience and advice over what the possibilities / dangers are....
e.g. images for an application e.g. blog, that I have activated for a client - how do I reference those images
e.g. Can user controls be dynamically added to a web application (which is pre-compiled unlike a website - it must be a web application since I am using web deploy).
e.g. Modification of web.config to add additional routing (doesn't matter if app has to go down to do this).
I can upgrade websites features en-mass, rather than manually enhancing each individual website which given a certain amount of clients would result in an awful amount of time lost.I do not have access to sharepoint (nor do I intend to). how to automate modularity completely via a front end in asp.net would be superb! how to reference files and resources outside of the websites directory and without using virtual directories
need to turn off the cookies in my ASP.net site completely
I'm doing some funky stuff serving images and scripts from a .aspx file, which causes the request to have cookies tagged to it.
So, how do I get rid of these?
I've tried setting the SessionState mode="Off" in the web.config, but that didn't seem to work.
Is there any way to completely ignore line break and tab characters etc. in RegEx?
For instance, the line break and tab characters could be found anywhere and in any order in the content string.

Our current web portal at work was a port from a classic ASP codebase. Currently, all pages in our project extend a custom Page class called PortalPage. It handles login/logout, provides access to a public User object for the currently authenticated user, and adds the standard page header and footer to all of our pages. Every Page in our site is 100% designed in the codebehind. The ASPX page is not used at all. Every single div, img, and block of text is allocated as an object and added from a C# function, even if it is completely static content (which we have a decent amount of). Example for a page header:
HtmlGenericControl wrapperDiv = new HtmlGeneric("div");
HtmlAnchor bannerLink = new HtmlAnchor();
HtmlImage banner = new HtmlImage();
bannerLink.HRef = "index.aspx";
banner.Src = "mybanner.png";
banner.Alt = "My Site";
bannerLink.Controls.Add(banner);
wrapperDiv.Controls.Add(bannerLink);
this.Page.Controls.Add(wrapperDiv);
Even worse, all Javascript is added to the page as a giant mess of string concatenations:
ClientScript.RegisterClientScriptBlock(this.GetType(), "javascript", @"
<script language='javascript'>
fullUrl = '" + ConfigurationManager.AppSettings["fullUrl"].ToString() + @"';.............

I want to create a complete dynamic view engine in that absolutely all html content will be loaded from a database. This is so I have a templating engine that is totally customisable. I have something similar in classic asp and the way that works is with fillpoints so you have a master page html which will just be a string when extracted from the database and then content is dynamically added to the string to sections identified by a fill point. So for example I have my master page content loaded into a C# string and I want to load a main view and a partial view onto the page, how would you go about that in MVC? I guess I would have to keep the fill point idea as there is no other way to know where the content will go. I'm just after opinions from the community really on how to go about it.
View 3 RepliesWhat I have is a masterpage with some tables and contentplaceholders. What I want in some pages is that a table be removed because i have 3 columns on 3 tables and i need 2 columns only(so minus one table). Now i can access the table and give it some css through code but what i give is width:0 (and visibility:hidden if ever successful). The table contains one contentplaceholder inside a <td>. I can also access the td.The problem is that the table (thus contentplaceholder) will not go away.
It remains as entity as extending the second column will just push it downside(behavior expected when the column3 with contentplaceholder is present). So is there a way to remove the table holding the contentplaceholder?Only thought is to hide it and push it right that i admit i haven't tried it yet, I suppose it would be easier to make another master page but the problem is that i want specific designs on many pages so if this does not work i would either have to make many master pages or just use simple pages.
