.net - Invalid Viewstate Error - OnPreRender?
Jan 19, 2010
I'm getting 100+ errors per day on my website with System.Web.HttpException: Invalid viewstate. The website is asp.net 3.5 running on iis6 , not running in a web-garden/web-farm , single server.Here are a few sample errors.
Machine: ML Framework Version: 2.0.50727.3603 Assembly Version: 6.5.3664.33889
Source: http://www.domain.com/WebResource.axd?d=z5VmXXoSLLpQHoPictureAlert
Exception: System.Web.HttpException: Invalid viewstate. at System.Web.UI.Page.DecryptStringWithIV(String s, IVType ivType) at
i already tried wraping all inline javascript with //<![CDATA[ //]]>
i already set enableViewStateMac to false.From looking at all the errors guessing out of the "d" paramter it seems to focus on a single usercontrol on my website.in this control i change the visiblity of div's + text in the usercontrol OnPreRender function.
protected override void OnPreRender(EventArgs e)
{
base.OnPreRender(e);
PreparePage();
}
Can the errors be related to the usercontrol behavioral?

I am having this problem with, it seems, Viewstate. This issue only occurs on certain machines, if I browse the website myself it works fine but if another user browses the pages they will lock up and timeout with the error "Viewstate verification failed. Reason: Viewstate was invalid." appering in the event log. Full error is as follows:
Event code: 4009

I have a DevExpress grid that needs to be refreshed every time the value in a combobox is changed. For example, I have a combobox that sets the grid's page size. One of the requirements is that the combobox does not cause a full postback.
The combobox is declared like this:
<asp:DropDownList ID="cboPages" AutoPostBack="false" runat="server"
EnableViewState="false" OnSelectedIndexChanged="cboPages_SelectedIndexChanged" />
On selected index changed, it sets a cookie whose value is the selected value. When the combobox value changes, a javascript function is called:
function PerformCallbackOnGrid(grid) {
try {
grid.PerformCallback("refresh");[code]....
The function is attached in code behind: this.cboPages.Attributes["onChange"] = "PerformCallbackOnGrid(" + this.GridClientID + ")";
After performing these steps:The user changes the grid page size using the combobox, so PerformCallback is called at least once.
The user presses F5(refresh).
The user tries to change the page size again.
an 'Invalid viewstate' error message appears.
I have tried setting ViewStateMode to Disabled for the grid, also EnableViewState="false".

I am trying to execute a CREATE TABLE which results in the following SQL exception:
Invalid object name 'UserLock'.
The statement looks like this:
USE [db]
GO
CREATE TABLE [db].[dbo].[UserLock] (
[Login] [varchar](150) NOT NULL,
[ExpirationDate] [datetime] NOT NULL,
CONSTRAINT [PK_UserLock] PRIMARY KEY CLUSTERED
([Login] ASC)
WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
The strange part is that I can run the query successfully inside the Microsoft SQL Management Studio with the same user but not within my .NET web application written in C#. I am not using any frameworks and I connect to the database with the provided classes out of System.Data.SqlClient. All other database queries work within the app. The database is Microsoft SQL Express 2005.
-- Edit ---
This is how my execution code looks like:
string createString = "CREATE TABLE [" + catalog + "].[dbo].[UserLock]("
+ " [Login] [varchar](150) NOT NULL,"
+ " [ExpirationDate] [datetime] NOT NULL,"
+ " CONSTRAINT [PK_UserLock] PRIMARY KEY CLUSTERED "
+ " ([Login] ASC)"
+ " WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]"
+ ") ON [PRIMARY]";
SqlCommand createCommand = connection.CreateCommand();
createCommand.Connection = connection;
createCommand.CommandText = createString;
selectCommand.ExecuteNonQuery();
I catch the exception in another method. The SQL connection itself is beeing set up in antoher method, aswell. It's the standard SqlConnection connection = new SqlConnection(connectionString);

I am getting the following error when doing a search on my master page:-
Code:
Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.
Basically if I load the site from my development PC it works okay but if I go to a web page on my site and then try it I get this error. If I go to a page that does not get a rewrite it also works.
Here is my search button code:-
Code:
Protected Sub butSearch_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles butSearch.Click
If txtSearch.Text <> "" Then
Session("SearchFor") = txtSearch.Text
Response.Redirect("~/Search.aspx")
End If
End Sub

I don't know what is causing this. The weird thing is, eventually, it goes away (as in, i get to see the web application form), BUT my web app does not work properly. I have image buttons that are not showing the image that I set at imageButton.ImageUrl. It works fine when I run it on my local machine (IIS), but when I try it on one of those free hosting sites, it will go as far as showing the interface (which has the image buttons), but when I click, it suppose to be set with an image.
btw, the first aspx page contains a ListView control, then after clicking on a button in that page, it goes to another page that contains a bunch of imagebuttons and an ajax timer control. I get the " Validation of viewstate MAC failed" error AFTER clicking on the button (in the ListView page).

I am using a Datapager in my project with a ListView control. The Datapager is set to use a querystring value Page, so that a typical URL looks like: [URL]. The problem is that the ListView throws an ugly error if the pageview is invalid (0, for example).
The error is:
Specified argument was out of the range of valid values.
Parameter name: startRowIndex
The error originates in the ListView SetPageProperties method. What is the best way to address this? Can I override the SetPageProperties method in some way, to check the startRowIndex parameter? Here's a very simple page that replicates the error: [URL]. A copy of a simple webapplication project demonstrating the error: [URL]

Getting an error whenever we click a particular button/link on our site. It is generating a javascript "Invalid Argument" error. I know in the other posts it is typically because it is a syntax error in the javascript however it only just seems to have started happening and it doesn't happen on all pcs.
ie. in our client's environment if I remote onto their web server and view the uat website I get the javascript error. If I remote onto their sql server and view the uat website I don't get the javascript error. If it was a syntax error then I would always get the error wouldn't I?
both browsers are the same version of IE6 (yeah I know...) :) I have tried deleting temporary internet files - including viewing the files and deleting them myself - but no joy.
client uses citrix.. and they're all getting the error :(
Update - I haven't posted specific code as there is too much to post (and I'm not sure where the error is occurring). The "button" launches a new window which in turn opens up a couple of aspx pages and calls lots of javascript. So the window opens ok, and there's a function that gets called to resize the window - but before it calls the resizing of the window/content it throws the invalid argument error. Am busy trying to get alerts to trigger to see if I can see where it's falling over but so far no luck.
Again not sure why this error doesn't occur when I use a particular PC (same browser version)

My original understanding was that the asp.net page lifecycle is run once for all pages and controls under normal circumstances. When I attached a control during a container's OnPreRender, I encountered a situation where the control's OnInit was not called. OK, I considered that a bug in my code and fixed as such, by attaching the control earlier.
But just today, I encountered a situation where OnInit for a control seems to be called after the normal OnInit has been done for everyone else. See stack below. It seems that during the page's PreRender, the control's OnInit is called as it is being dynamically added.
So I just want to confirm exactly what ASP.NET's behavior is? Does it actually keep track of the stage of each control's lifecycle, and upon adding a new control, it will run from the very beginning?

I am getting the following error as Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. when an invalid value is passed in dropdown with autopostback=true. What should I do. I want the solution with "EventValidation=true" and "ValidateRequest=true" in the Page directives. Also without any Custom Error Pages Enabled in web.config file i.e Custom Error Pages are off in web.config file.

I am making a call to a WCF service(Existing) from another WCF Service(New, my service), which is configured as Anonymous access. I did a service reference of my service to web application both under same solution file and web app is configured as Windows Authentication. When I call the existing WCF Service from my web app directly, everything works fine, but when I call the same existing WCF Service from my service, I got a "user does not have valid credentials" error. To avoid this error, I published my service to a server and referenced that URL to my web app. Though I got past the error, now, I am getting "Invalid Argument" error. No further information on the error.
Error source is MSCORLIB. There is no problem in the code of my service and the existing service, because if the same value that I get from the existing service is hard coded, then everything works fine. The existing service is used by many other app and it works fine. So, its a tested service. I tried to find a solution of "invalid argument" and I found few threads where others are facing the same problem when they publish a WCF service, but I did not find any proper solution for this.
