Web Forms :: Machinekey With Explicit Validationkey?

Dec 2, 2010

I had "Invalid viewstate" error in my application; I found out it's caused by worker process recycling, so I generated a <machinekey> section with explicit validationkey. refer to this link,[URL] My quesitons are 1. I have the application installed on dev, qa, stg and prd servers. Should I use the machinekey with the same(or different) validationkey for all the servers? I think it shouldn't be matter because the servers are independent from each other.

2. Where should I put the <machinekey> section, machine.config or individual application level's web.config? There are multiple applications on the server.

If I put it at the application level, does that mean other applications still may have the same "Invalid viewstate" error?

If I put it at the application level, should I add the <machinekey> section for all the other applications using the same validationkey?

Web Forms :: Specify Explicit ID To Usercontrol?

May 18, 2010

User controls when rendered generates a dynamic ID for themselves. It makes sense also, as a page might have more than one of such user control and if dynamic id is not generated, there would be an ID conflict. But I am working on a page (legacy page yopu can say :D ) where I really need to specify a specific ID to usercontrol to make existing javascripts work. Is there a way to achieve this? OR if above is not doable (though I prefer it), below I have a dropdown in aspx like

.net - Leveraging MachineKey For Encrypting Own Data?

Sep 10, 2010

I have some data I want to encrypt in an ASP.NET MVC application to prevent users from tampering with it. I can use the Cryptography classes to do the actual encryption/decryption, no problem there. The main problem is figuring out where to store the encryption key and managing changes to it.

Since ASP.NET already maintains a machineKey for various things (ViewData encryption, etc), I was wondering if there were any ASP.NET functions which let me encrypt/decrypt my own data using the machineKey? This way I would not have to devise my own key management system.

MachineKey Config Section Default Location?

Sep 21, 2010

Where do I find the machineKey config section for ASP.NET?

I don't have one in my application Web.config, there isn't one in the root Web.config and there isn't one in my machine.config.

Does this mean there is some other default hardcoded into ASP.NET? If so, what are the defaults? (For .NET 2 and 4)

Having read this: [URL]

i was expecting to find something like this, somewhere:


Edit: the 1.1 docs seem fairly clear wrt default values: [URL] but the 4 docs are rather ambiguous [URL]

How To Modify MachineKey For Session State Server

Jul 20, 2010

I'm trying to implement a SessionState server to allow multiple web servers to share the same state. At first this will be the different dev machines, and later it'll be the different web servers in the web farm.

So far, I'm making good progress I think, but one of the requirements has me confused. In order to implement this, I need to make sure that all web servers are using the same machine key.

This is a sample MachineKey taken from my local dev machine:


If we have a Session State Server deployed locally, do I need to ensure that all other machines using this service (specifically, the other devs working on the same project, and then when we deploy to the web farm) have the exact same entry in their Machine.Config files?

Or do I have to somehow generate a new machine key that can apply to all the machines?

Security :: Membership, Password Hashes And MachineKey?

Jun 29, 2010

I have a question about the encryption key/keys the standard ASP.NET Membership provider uses for creating the password hashes.Although we haven't deployed this new system we are working on yet, we might switch servers in the future. So I thought it might be a good idea to specify the encryption key/keys in the web.config file to avoid any problems with mismatched hashes if we do switch servers.We use the standard ASP.NET Membership provider ("AspNetSqlMembershipProvider"), passwordFormat is set to "Hashed" and we use Forms authentication.The current web.config file initially did not have any machineKey element. I used the web application and had registered and thus created an account and the hash of my password is stored in one of the aspnet_* tables.Then I created a machineKey element in the web.config file, and specified validationKey, decryptionKey, validation and decryption attributes. I had expected not to be able to log in with my password anymore, but I was surprised that I could still do so with the existence of the new machineKey specifying new encryption keys.So - why can I still log in?Does the AspNetSqlMembershipProvider not use the encryption keys specified in machineKey?

Configuration :: Theoritical Problem When Encryptin Machinekey

I encrypt my machinekey with aspnet_regiis The problem is on this lines on web.config.


on the first line The 'configProtectionProvider' attribute is not declared on the second line The element 'machinekey' cannot contain child element 'http://www.w3.org/2001/04/xmlenc#Element:Encrypteddata' because the parent element content model is empty.I've read that it has something to do with intellisence and the application will work ok.

Setup Identical <machinekey /> Sections On Each Servers .config File?

Mar 2, 2010

We have a scenario using asp.net Forms Authentication in a web farm and need to setup identical <machinekey /> sections on each servers .config file.

Is it better to store the <machinekey /> section in machine.config rather then web.config? what's the advantages and disadvantages of each approach concerning security?

<machineKey validationKey="[keyhere]"
decryptionKey="[keyhere]" validation="SHA1" />

If its not secure enough, is there any way to encrypt <machinekey /> section like we encrypt our connectionsstring (with DPAPI)? (http://msdn.microsoft.com/en-us/library/ms998280.aspx)

Adding MachineKey To Web.config On Web-farm Sites / Padding Is Invalid And Cannot Be Removed

Oct 4, 2010

We (out IT partner really) recently changed some DNS for a web farmed site we have so that the two production server have round-robin DNS switching between the two. Prior to this switch we didn't really have problems with WebResource.axd files. Since the switch, when we hit the live public URL, we get an error:


Padding is invalid and cannot be removed.

When we hit the specific servers themselves, they load fine. I've researched the issue and it seems since they're sharing assets between two servers, we need to have a consistent machineKey in the web.config for each server so they can encrypt and decrypt consistently between the two. My questions are:

Can I generate a machineKey via a tool on the server, or do I need to write code to do this?

Do I just need to add the machineKey to the web.config on each server or do you think I'll need to do anything else to make the two server work together? (Both web.config's currently do not have a machineKey)

SQL Server :: Where Is Statement In XML Explicit

Dec 27, 2010

I've build a query, but the where statement is doing strange things. First my query:

select * from
SELECT 1 as Tag, null as Parent, row_number() OVER (ORDER BY tblOccasion.ID DESC) AS [tblOccasion!1!rownum], FROM tblOccasionwhere tblOccasion.UserID = @UserName and ((tblOccasion.MerkDesc like '%' + @search + '%')or(tblOccasion.UitvoeringDesc like '%' + @search + '%')or(tblOccasion.UitvoeringDesc like '%' + @search + '%'))
) AS A where a.[tblOccasion!1!rownum] BETWEEN (@startRowIndex) AND (@startRowIndex+@pageSize)
order by a.[tblOccasion!1!MerkDesc!Element],a.[tblOccasion!1!TypeDesc!Element],a.[tblOccasion!1!UitvoeringDesc!Element]

But the result should be ordered by Merkdesc, then TypeDesc, and then as last the uitvoeringDesc.
So for testing i only used the MerkDesc. The strange thing is that i get the result:


But this was page 1, on page 2 (paging) you got BMW again... so he takes the first 5 rows ore something and then the order. But i like that he first orders it by MerkDesc and then picks the first 5. How can i change that, i can't add a Order by in the inline sql statement i get this error: Msg 1033, Level 15, State 1, Procedure MijnAdvertenties, Line 47 De ORDER BY-component is ongeldig in weergaven, in line functies, afgeleide tabellen en algemene tabelexpressies, tenzij ook TOP of FOR XML is opgegeven.

Explicit __doPostBack() - Page_Load Is Calling Twice By Clicking The Button

Sep 19, 2010

I have explicitly added __doPostBack() on Button onclientClick event.

<asp:Button ID="Button1" runat="server" Text="Button"

When I am clicking the button the Page_Load is calling twice. But if I am adding below code inside page load ,page load is calling only once on button click.

Button1.Attributes.Add("onClientClick", "__doPostBack('Button1','')");

Again if i add with return false it is giving me it calling only once page load on click

<asp:Button ID="Button1" runat="server" Text="Button"
OnClientClick="__doPostBack('Button1','');return false;"/>

and return true is giving me again twice page load ,but adding return true or false in attribute.add code is giving the same result ,only one page load call.

Button1.Attributes.Add("onClientClick", "__doPostBack('Button1','');return true;");

I am not able to understand what is going on exactly when I tried to add __doPostBack in different way.

AJAX :: Including JQuery Using ScriptManager Explicit Mode

Nov 23, 2010

Is there a way to use the .NET ScriptManager in Explicit mode to inlcude the CDN JQuery file(s)? There is plenty of dicussion and information about including the indivudual AJAX framework files such as "MicrosoftAjaxCore.js", but since AJAX uses JQuery, I thought there might be a way to explicitly include the JQuery file(s) using the ScriptManager rather than hard coding an address to the MS CDN.

Explicit Localization - Translate The Confirmation Message To Norwegian

Mar 2, 2010

when trying to translate the confirmation message to Norwegian i get the following error: Cannot have more than one binding on property 'OnClientClick' on 'System.Web.UI.WebControls.LinkButton'. Ensure that this property is not bound through an implicit expression, for example, using meta:resourcekey. i use Explicit localization in the following manner:

<asp:LinkButton ID="lnkMarkInvoiced" runat="server" OnClick="lnkMarkInvoiced_OnClick"
OnClientClick="<%# Resources: lnkMarkInvoicedResource.OnClientClick%>"
Visible="False" CssClass="stdtext" meta:resourcekey="lnkMarkInvoicedResource" ></asp:LinkButton>

here's the local resource file entry:

<data name="lnkMarkInvoicedResource.OnClientClick" xml:space="preserve">
<value>return confirm('Er du sikker?');</value>

if i remove the meta attribute i get the English text(default). how do i get the Norwegian text appearing without resorting to using the code behind? Update: removing the meta attribute prevents the exception from occurring but the original problem still exists. I can't get the Norwegian text to show. only the default English text shows.

Another Update: I know this question is getting old but i still can't get the Norwegian text to display.

C# - Explicit Localization - Parsing Of A Resource Required To Service

Jan 11, 2011

I have some problem with the Localization in ASP.net. I have generated the resources and binding the text property by an variable. In the source file.

<asp:Label ID="Label1" runat="server" Text='<%# Eval("name") %>' meta:resourcekey="Label1Resource1"></asp:Label>

code behind

protected string name;
protected void Page_Load(object sender, EventArgs e)

The above things are simple but when I run the project. I got Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: Cannot have more than one binding on property 'Text' on 'System.Web.UI.WebControls.Label'. Ensure that this property is not bound through an implicit expression, for example, using meta:resourcekey. Source Error: The above is just an example what I am facing in my project. how can I make localization and binding both at the same time.

Forms Data Controls :: Error When Inserting Into Table - Cannot Insert Explicit Value For Identity Column In Table

Aug 11, 2010

I am working on a web app for an online photo album. It is the last project in Scott Mitchell's book: "ASP.Net 2.0 in 24 hours".

I am creating a page where users can enter new photo images. The functionality for uploading an image will come later. I am working on just inserting a new row into the Pictures table with an optional category, a required title and a required description.

I am getting an error when I try to insert a new row.

Here is a screenshot of the page with a shot of the dropdown list.

The Categories are user-specific. I am getting the correct values retrieved.


There are two pretty simple database tables involved here.

NOTE: The CategoryID and PIctureID are both autoincrement integer columns.


The page uses a DetailsView that uses a SqlDataSource that uses the Pictures table. (The DetailsView's Default Mode property is set to "Insert". The "Enable Inserting" checkbox is also checked.)

The dropdown list uses a dropdown control that uses a SqlDataSource that uses the Categories table.

When the "Insert" button is clicked the CategoryID value associated with selected (Category) Name on the dropdown list will be used along with the Title and Description values to insert a row in to the Pictures table. (If no Category value is selected, then a null value will be used for the CategoryID. This is OK because the CategoryID column in the Pictures table allows nulls.)

My problem is that I am getting this error:

Cannot insert explicit value for identity column in table 'Pictures' when IDENTITY_INSERT is set to OFF.

(FYI: I have the full version of both Visual Studio and SQL Server.)

Here is my source code for the page:
