This bug is very difficult to troubleshoot. I run 4 apps on the same server, all 4 are clones from the first one, just differ on their database connection. 2 run perfectly, but on two of them, when making a postback from a certain page, by clicking a button or by changing a datagrid page, it throws this error:

I'm trying to validate that a GridView logated in one of the steps of the Wizard Control is populated by the user before the Next button is clicked. What I mean is that I need to block Next (or Prev) button until the user populates a gridview, once the gridview has at least one element then enable the (Next/Prev) buttons. How can I enable/disable Next/Prev buttons within a specific step?.

I'm trying to php/curl scrape data from an .NET site (those with __VIEWSTATE, __EVENTVALIDATION). I monitor headers and post vars using Tamper Data so I'm pretty sure I haven't missed anything. My approach is to micmic the post back when the user click on one of the links and parse the response. But the response I'm getting is a page redirect to "Unable to validate data".

I'm developing and maintaining an ASP.NET web site.
The site is hosted at the 3rd party company running IIS6.
Recently the hosting service provider has setup an additional IIS server and moved part of the applications to this new server. This moment, my application is installed on both old and new servers.
Although the hosting provider claims that IIS configuration on the both servers is absolutely equal, I get the following exception on the new server, while on the old one everything works like a charm.

According to the service provider in both cases my application runs under Network Service user account.
An additional observation: retrieving the "System.Environment.UserName"
shows "Network Service" on the old server and "IUSR_XXX" on the new one.
I loose my head trying to understand what is different and what I need in order to make the things working.
For the heck of it, I decided to run my ASP.NET MVC 2 app in VS2010 with first chance exceptions enabled. I noticed a first chance exception in our custom ControllerActionInvoker. It appears to be non-fatal but seems to happen frequently. Concerned this could be slowing the web app down.

I'm working on a website powered by .NET asp/C# code. The clients require that sessions have a 25 minute timeout. However, sometimes the site is used, and a user stays connected for long periods of time (longer than 25 mins). Session_End is triggered:
protected void Session_End(Object sender, EventArgs e)
{
Hashtable trackingInformaiton = (Hashtable)Application["trackingInformation"];
trackingInformaiton.Remove(Session["trackingID"]);
}
The user returns some time later, but when they interact with the website, they get an error, and we get this email notification:
User: Unauthenticated User
Error: System.Web.HttpException
Description: 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...
The telling part of the stack trace is System.Web.UI.Control.AddedControl. Apparently, the server has thrown away the session data, and is sending new data, but the client is trying to deal with old data. Hence the error that "the control tree into which viewstate is being loaded [doesn't] match the control tree that was used to save the viewstate during the prevoius request."
So here's the question. How can I force instruct the user's browser to redirect to a "you're logged out" screen when the connection times out? (Is it something I should add to the Session_End method?)
I am developing a C#/SQL ASP.NET web application in VS 2008. Currently I am using the Server.Transfer method to transfer control from one ASPX.CS file to another ASPX file. The first time through, this works. But after control is transferred to this new file it encounters a condition:
if (restart == false)
{
where "restart" is a boolean variable. After this statement it immediately transfers control back to the same ASPX.CS file and tries to reexecute the Server.Transfer method. This time it gives me the following exception and stack trace. Do you know what is causing this? I tried to read this but it didn't make much sense to me.
System.Web.HttpException was unhandled by user code

I ran into this error today and much googling didn't get me the answer. I have been for years now publishing this particular site by simply doing "Publish web site" and then supplying it a UNC path, then I go to the server delete the old bin and copy to the new bin folder to the live site, this has always worked except today I started getting the "cannot be requested" error for certian pages in certain directories. Everything else worked and after several attempts nothing else broke and only these same certain few pages where screwed up - there was nothing exciting about any of these pages, in fact they were part of the admin portion of the site and were very simple
View 2 RepliesI'm trying to return an error page indicating that the user couldnt be found and therefore I throw a HttpException with status code 404, however for some reason it wont redirect to the error page? - Is there some sort of trick to handle error pages with JSON that I should be aware of? My current code:
public ActionResult Details(int id)
{
User userToGet = _session.Query(new GetUserById(id));
if(userToGet == null)
{
throw new HttpException(404, "User not found");
}
DetailsUserViewModel userToViewModel = AutoMapper.Mapper.Map<User, DetailsUserViewModel>(userToGet);
return Json(new
{
HTML = RenderPartialViewToString("Partials/Details", userToViewModel)
}, JsonRequestBehavior.AllowGet);
}

// MyJs.js
function openBox(object) {
$("body").append("<div id='fadeBox'></div><div id='overlay' style='display:none;'></div>");
$("#fadeBox").html("<div style='position:absolute;top:0;right:0;margin-right:2px;margin-top:2px;'><a id='closeBox' href='#'>x</a></div>" + object["HTML"])
$("#fadeBox").fadeIn("slow");
$('#wrapper').attr('disabled', 'disabled');

We're having an issue with a .NET 3.5 WebForms site where occasionally our error logs start filling up with the following error message:
"Multiple controls with the same ID 'ctl09' were found. FindControl requires that controls have unique IDs."
I know very little about the exception as I have never seen it while debugging locally and have never caught it in the error logs soon enough to run a remote debugging session. I do know that an application pool recycle fixes the issue.
This only affects a single [high traffic] page in the site. The strange thing is that the site uses the pre-4.0 ID generation logic. So, when the page is working, there isn't an html element in the entire view source that isn't some autogenerated control ID prefix followed by a the 'actual' IDs (i.e. ctl09_someID_someOtherID).
What would case a control to randomly stop being built correctly? Other than the Global.asax, how can I trap this error and force the control to ... recompile? App pool to recycle?
I developed an asp.net mvc application. In one of my forms, I'm getting a following
exception:
A public action method 'UpdateBasket' could not be found on controller 'App.Controllers.WebShopController'
But the funny thing is, that form submit works (even in debug mode) and finds an
ActionMethod UpdateBasket and returns View. The problem is that because of that html generated error w3c validators and google crawlers can't access the site (I think so, correct me if I'm wrong).
