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 have an ASCX control which is a special dropdownlist. I add that control dynamically to the page and fill it with data. This control has a postback that will change the contents of a second dynamically created standard dropdownlist.
When I change the selection on the first dropdown, the indexchanged fires and I get new data and attempt to place it in the second dropdownlist's items collection, by first clearing it then filling it with new data.
This works fine the first time a change the selection, but when I select a second time the following error is thrown:
The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request.
I'm not adding or removing new controls in the fired event, only changing data. And again, it works the first time, but doesn't subsequent times.
If I disable stateview on the child control, then the control just doesn't get updated with data at all.
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 had to switch to
sessionState
mode="StateServer"
timeout="30"/>

I am recently trying to set enough permissions to let web application write entries in System's "Event Log" .The following are the lines of code i added in web.config files:
<securityPolicy >
<trustLevel name="Full" policyFile="internal" />
<trustLevel name="CustomMedium" policyFile="customWeb_mediumtrust.config"/>
</securityPolicy >
<trust level="CustomMedium" originUrl=""/>
And here goes the html markups inside of customWeb_mediumtrust.config:
<configuration>
<mscorlib>
<security>
<policy>
<PolicyLevel Version="1">
<SecurityClasses>
<SecurityClass name="EventLogPermission"
Description="System.Diagnostics.EventLogPermission,System,Version=2.0.0.0,Culture=neutral,PublicKeyToken=b77a5c561934e089"/>
</SecurityClasses>
<PermissionSet version="1" Name="ASP.NET">
<IPermission Version="1">
<Machine name="." access="Write"/>
</IPermission>
</PermissionSet>
</PolicyLevel>>
</policy>
</security>
</mscorlib>
<appSettings></appSettings>
<connectionStrings/>
</configuration>
The problem at the moment is that web.config generates the error "invalid syntax" if i include the line: <trust level="CustomMedium" originUrl=""/>. In case i remove the line , site compiles successfully. Did i go wrong any where with the above codes.

I am looking for an event firing before a DropdownList auto-postback to save Listbox items (populated with JS) in the ViewState.I tried the OnSelectedIndexChanged event but it's fired too late.
View 5 RepliesI have a CheckBox on an ASP.NET Content Form like so:
<asp:CheckBox runat="server" ID="chkTest" AutoPostBack="true" OnCheckedChanged="chkTest_CheckedChanged" />
In my code behind I have the following method:
protected void chkTest_CheckedChanged(object sender, EventArgs e)
{
}
When I load the page in the browser and click the CheckBox it becomes checked, the page posts back, and I can see chkTest_CheckedChanged being called.When I then click the CheckBox again it becomes unchecked, the page posts back, however chkTest_CheckedChanged is not called.The process is repeatable, so once the CheckBox is unchecked, checking it will fire the event.I have View State disabled in the Web.Config, enabling View State causes this issue to disappear. What can I do to have reliable event firing while the View State remains disabled?Update:If I set Checked="true" on the server tag the situation becomes reversed with the event firing when un-checking the CheckBox, but not the other way around.Update 2:I've overridden OnLoadComplete in my page and from within there I can confirm that Request.Form["__EVENTTARGET"] is set correctly to the ID of my CheckBox.
I have a TabContainer, within a tab, i have a gridview, within the gridview i have a ImageButton. When I click on the ImageButton, I will call a javascript. The javascript will call a Hidden Button click. This hiddenbutton is the TargetControl of the Modalpopup so that when I click on the ImageButton, modalpopup is trigger. The Popup panal, Hidden Button and ModalPopupExtender below:
<asp:Panel ID="panEditAccessLog" runat="server" CssClass="gc_modalPopup" Style="display: none" BorderWidth="0px">

View 2 RepliesI haveMaster Page -> ASPX page -> User ControlUser control page is contains all dynamic bind controls (e.g Repeater) depended on ASPX Page (Only one parameter say ItemNo)The problem is, if I bound user control on page load event with passing respective parameters then it's create to much view state (I checked source file and it's almost 1.5 MB)In other way if I put one textbox, and a command button and I pass required parameter on button click and load the control then page size is ok (I checked and it's < 500KB)

SelectedIndexChanged event doesn't fire for the first item of the DropDownList. For any other item SelectedIndexChanged fires, but not for the first one.Could someone, please, explain what kind of magic is it?(I use Visual Studio 2008)
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 keep getting the error ') expected' and 'Invalid expression )' on the following code:

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 have all application errors sent to my email. I keep getting this:

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]

I have the above error while deploying the svc file via IIS 7 but when I deployed it via VS 2008 everything works ok.note I have checked the web site configuration to map to asp.net 2.0 and added the handler mapping for .svc file in IIS 7 but no luck.
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)
