On page1.aspx i hava a textbox with id="tb1"
On page2.aspx I have a textbox with id="tb2"
page2.aspx is set as postbackurl for page1.aspx. For both labels enabl;eViewState is true. Shouldn't the text I write in page1 also appear in the label on page2? Can I implement this without looking into Request headers, and setting the text myself?
I need a way to save and load the Page State in a persistent manner (Session). The Project i need this for is an Intranet Web Application which has several Configuration Pages and some of them need a Confirmation if they are about to be saved. The Confirmation Page has to be a seperate Page. The use of JavaScript is not possible due to limitations i am bound to. This is what i could come up with so far:
[code]....
I can't seem to find a way to load the Page State after being redirected from the Confirmation.aspx to the PageToConfirm.aspx.
I have a question regarding disabling viewstate.
I know how to do this in the page, however if I disable in a master page will all child pages and controls be disabled through inheritance?
After witnessing some strange behvior I'm confused about ViewState again :/
My understanding was a textbox needed to have "EnableViewState" set to true otherwise when the you postback the fields contents would disappear.
That's not happening, I created a textbox and button and a label.
The button was set to copy contents of text box into the label when I pressed it.
I did and the text was populated into the label and remained in the textbox?
This was inside an UpdatePanel and the page itself has a MasterPage, so that might have something to do with it, but I have about 50 textboxes on this page all with viewstate=true on, so I would really like to know what controls need to have enableViewstate=true in order o function properly.
Now 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:

I have problem getting values from viewstate in GetTopThemes.

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 bind textbox to a property of an object. After running the app, if the value of textbox is changed, I expect the object to update this property .This does not happen. I also understand that I am recreating the object from viewstate on postback, which is wrong. how to persist the state of object on postbacks all.

My web form works perfectly for me when on development and after publishing on IIS but when I try to access remotely the session value is always null.
I do these things in the following order and when accessing remotely I always get the exception i throw when session is null.
I debugged it and my list is never null when reaching the assignment point.

View 4 RepliesI have an object to hold some specific state information in my web application - I pass it back & forward between pages by making it a property of a basepage which works fine, but I lose it on postback.
Is there any way to persist this property without manually adding & reading it again from viewstate?
In my Application_BeginRequest I have code that gets query string value ?c=FR or ?c=US and store it in cookies.Based on query string value I have either US or FR,locale is selected from locale table.If ?c=FR then locale will be fr-FR and if it is US then locale will be en-US.My code is below.
void Application_BeginRequest(object sender, EventArgs e)
{
LocalizationInfo loc = GetLocalizationInfo();
if (Request.Cookies["Localization"] == null)
Response.Cookies.Add(new HttpCookie("Localization"));
Response.Cookies["Localization"]["Country"] = loc.Country;
CultureInfo objCI = new CultureInfo(loc.Locale);
Thread.CurrentThread.CurrentCulture = objCI;
Thread.CurrentThread.CurrentUICulture = objCI;
}
public static LocalizationInfo GetLocalizationInfo()
{
string countryCode = "";
string sLocale = "";
if (HttpContext.Current.Response.Cookies["Localization"]["Country"] != null)
countryCode = HttpContext.Current.Response.Cookies["Localization"]["Country"];
if (!string.IsNullOrEmpty(HttpContext.Current.Request.QueryString["c"]))
countryCode = HttpContext.Current.Request.QueryString["c"];
if (countryCode == "")
countryCode = "US";
sLocale = HertzRent2Buy.DataProvider.ListData.GetLocale(countryCode);
LocalizationInfo ret = new LocalizationInfo();
ret.Country = countryCode;
ret.Locale = sLocale;
return ret;
}
public struct LocalizationInfo
{
public string Country;
public string Locale;
}
Now when I run the project and in query string I set [URL] then for the very first page(home page itself) it shows me French translation,but on subsequent page,that query string parameter ?c=FR is lost and hence it shows be English translation not French translation since it does not pickup French resx file.If I manually append ?c=FR in subsequent page then it shows the French translation.Is there is way how I can make that query stringparameter available in all pages.Structure is there to hold Country and locale variables. In all pages I am calling GetLocalizationInfo() method as follow
LocalizationInfo info = some.DataProvider.Globalization.GetLocalizationInfo();
And I create instance info to pass locale and country as parameter. GetProductDetails(id,info.Country,info.locale). why my query string parameters get lost on subsequent pages.
I want to disable viewstate for nearly all of my pages and I have used the element to do so in my web.config.On a page that specifically uses viewstate, I used the EnableViewState=true. However the page fails to work and the dropdownlists that depended on viewstate are not filled in the postback.How can I enable ViewState for some Pages when it is disabled in WebConfig?

View 2 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 start with a blank ASP.NET page where I disable ViewState for the whole page with EnableViewState=False and even ViewStateMode=Disabled.keep adding various controls to the page -- Label, Table, Calendar, TextBox, DropDownList.Everything looks good, i.e. my __VIEWSTATE tag fluctuates between 24 and 28 characters.As soon as I add a single RadioButton (or CheckBox), the __VIEWSTATE shoots up to 130 characters. And it keeps growing by over 100 characters every time I add another RadioButton.

View 3 RepliesI am creating a simple string of values that get added to a label after a post back. I am setting the values thorugh ViewState. However, my appended values do not get updated until AFTER the 2nd postback. Example:
On Page_Load the label displays a "0";
If I enter a "1" in the text box and click the button the label still displays a "0";
If I click the button again (the 2nd postback) then my label correctly displays "0,1"; This works for whatever value I enter after. i.e. "0,1,35,hello world", etc.
What I am I missing? Code Below.
