Invalid Viewstate Error When Posting Back To Same Page
May 24, 2012
I'm having some issues with an Invalid Viewstate error and I can understand why it's happening but I don't know how to fix it so I'm hoping someone can help.
I have a page which is similar to this /story/?id=123 but I'm using a different page to Server.Transfer to this page.
So I've set up /info to Server.TransferRequest("/story/?id=123") and it works fine until the page does a postback to itself.
We have a login form on this page which simply reloads the page but when it does it seems to add /?id=123 onto the end of the URL so it ends up like this /info/?id=123 thus causing an Invalid Viewstate error.
I've already tried adding EnableViewStateMac="false" - this fixes the error but it doesn't log the user in as expected so it does not give the required result.
Is there a better way to redirect to my page other than Server.TransferRequest but still keeping the nice URL? - I don't want to response.redirect if I can avoid it.

I want my ListBox control to respond dynamically to a change of selected item.However, "OnSelectedIndexChanged" fires an event only when AutoPostBack is set to true. Having a dozen of controls updating each time a user makes a change in selection insingle one is quite annoying and irritates a lot. Is it possible to enable

I keep getting the following error message when I run my vb.net web app:The state information is invalid for this page and might be corrupted.After a good search, I came across this Microsoft page, which describes the problem exactly. The likely cause seems to be "scenario 2":[code]I appear to have prevented this error from happening by using EnableEventValidation="False" in the Page node of the markup as recommended here.

I'm using Visual Studio 2005 and ASP. NET 2.0 with this program. This is written in VB.net
Right now, we've got a Gridview that is embedded and databound into another gridview. The 2nd Gridview is hidden by default and expanded by the user. Within the 2nd gridview are several DropDownLists. The problem is that these DropDownLists are not firing the OnSelectedIndexChanged functon nor AutoPostback whenever I change the selecteditem.[code]...

I am generating ListItems for a CheckBoxList control in ASP, but when I do something like the following:
...
Dim newListItem As ListItem = New ListItem("RoleName")
newListItem.Attributes.Add("style", "color:blue;")
CheckBoxListControlToFill.Items.Add(newListItem)
...
"RoleName" is maintained from post back to post back, but my style tag is dropped after the first post back. If I want to keep any attribute like this, do I need to re-add it every post back?

Is it possible to make the viewstate false of whole page including all controls at a time.I mean I don't want to set enableviewstate="false" for all controls..In the page directive of the aspx page I have made enableviewstate="false" but still viewstate of all the controls of the is enabled.. And what the EnableViewState="False"actually works within Page directive.

I have written methods to override the LoadPageStateFromPersistenceMedium and SavePageStateToPersistenceMedium methods. now the problem is that i am using a masterpage, so how do i maintain using my masterpage and still inherit from System.Web.UI.Page?
Bear in mind that the .vb Code behind the masterpage already inherits System.Web.UI.MasterPage. Anybody know how i can "properly" override these methods in a MasterPage?

Upon a javascript button click, I'm using jquery to post to a url:
$(".optionClick").click(function () {
var caseOption = $(this).attr('title');
$.post("../tracking/RecordClick.aspx?page=gallery&item=" + caseOption);
});
On the page being called, I'm using the following vb.net code to retrieve the querystring variables and write them to a database:Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
[Code]...
Each of the javascript blocks above worked locally as intended but failed in the same manner with multiple DB writes and Firebug "Aborted" status.If I call the url+querystring directly via the browser, everything works as expected. (Edit) Also tried using the full path url in the code above - no improvement.

I have a search page with a couple of pulldowns. Dependig on the values of them I show a grid matching the searched criteria, basically a table with links the user can navigate to. My problem comes when the user wants to navigate back. At the moment I have a "Back" button which simply redirects the user to the initial search page. I think it would be a good improvement to have the values of the pulldowns filled in with the values the user selected, this way when he presses the "Back" button he would not have to restart the whole search process again.

Clicking on a link button on a page causes Postback to a page containing a number of controls. [code]During the Postback to (page a) on the server, (page d) is requested when using the IE browser (doesn't happen in Firefox) there are absolutely NO artefacts requested that live on (page d), there are no response redirects or server transfers or anything referencing (page d).The only thing I have seen like this is when an image or artefact is requested and cant be found, or some pathing issues for an image, and this somehow screws the request up.

I have an asp.net website that is using update panels on the page that i cant get to reload from the server. I have this for the disable page cache on the master page.
'Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1))
'Response.Cache.SetValidUntilExpires(False)
'Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches)
'Response.Cache.SetCacheability(HttpCacheability.NoCache)
'Response.Cache.SetNoStore()
When I click the browser back button to go back to the page it says the page has expired. the other pages on my web site work and call the page load, the only solution i found but cant use is to wrp the whole page in an update panel, but i cant do this becuase i have a report viewer on the page that does not work with ajax.

I am redirecting to a page and passing some querystrings. My pages are in a masterpage in asp.net.
What I am trying to do is go back to the page that calls the current page via the button, btnBack.
I am using the Request.UrlReferrer.ToString() to get the String URL of the previous page but the URL equals nothing.
I placed my code in my form load if not ispostback.

If you do a search for "ie8 back button disabled" you'll see a number of blogs with people having difficulties with the Internet Explorer version 8 back button becoming disabled. This now happened to one of my ASP .Net pages. The page uses a user control, aspx page, and a master page. It uses no redirects and seems to be happening when I click the back button and then the forward button (after the forward button is clicked, it does not fire the Load event and the back button becomes disabled).

I have a need for a button to take the user back to their previous page.Because of how this page is accessed, the only way to do this is with javascript using history.back()
This part works perfectly apart from the fact when a user goes to click a button on the page they have gone to back to, I get the error that Request.QueryString is not supported in this context.I'm guessing the Request object is lost when javascript is directing the user to the previous page.I cannot use Request.UrlReffer either because the the nature of the back button. (it causes a loop at times).

I have three dropdown list boxes and a gridview. The gridview shows data based on what is entered in the dropdown list boxes. I have added a button that allows the user to insert a record into the database and then the page refreshes. The problem is that when the page refreshes the gridview goes back to whatever was initially in the dropdown list boxes when I first brought up the page. Is there a way to refresh and maintain the data in the list boxes so the gridview shows the same data? My code is below.

I have a popup aspx page that receives data from a parent page gridview Edit click. There is a great deal of parsing of data from parent page to pop up as the data is being translated in pop up, then sent back to parent page to be reassembled in the original text block before update.
When the popup passes the data back or is canceled, the parent page gridview is still in Edit mode.I would like to pass the Cancel or Update button click from the popup to the parent page gridview so it can complete the update or cancel event without asking the user to click the corresponding command button link from the gridview edit mode, to Update or Cancel.
UPDATE: There is also a jquery UIBlocker on the Parent page to prevent the user from returning to the page until the PopUp page processing has been completed. Below is the critical code:
PARENT Page:
function parentFunc(a) {
// Unblocks on return from popup page.
$.unblockUI({});
[code]...
Had a problem with preventing the popup from reloading. So there is an if condition in the load event. A dynamic number of controls are built on the popup as literals. So the Page Init event and Page Load event fire on non Postback to rebuild the controls.
