Το μήνυμα αυτό επίσης μπορεί να παρουσιαστεί αν έχεις ορίστει το property DataKeyNames στο GridView σου και φορτώνεις δυναμικά τα περιεχόμενα της σελίδας σου με τέτοιο τρόπο ώστε μεταξύ των postbacks το control να παίρνει διαφορετικό ID. Είναι αυτή η περίπτωσή σου;

Αν το site είναι σε webfarm (δηλαδή η ίδια εφαρμογή τρέχει σε πολλούς Servers ταυτόχρονα και όχι μόνο σε έναν) τότε θα πρέπει στο web.config (ή το machine.config) κάθε server να δηλώσεις ένα κλειδί (το οποίο θα πρέπει να είναι ίδιο σε όλους τους servers που τρέχουν το συγκεκριμένο web application, και μπορείς να χρησιμοποιήσεις αυτόν τον online generator).

Δυστυχώς αγνοώ σε ποια άλλη περίπτωση μπορεί να λάβεις το συγκεκριμένο μήνυμα.

Server Error in '/' Application.

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.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Web.HttpException: 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.

Source Error:


The source code that generated this unhandled exception can only be
shown when compiled in debug mode. To enable this, please follow one of
the below steps, then request the URL:

1. Add a "Debug=true" directive at the top of the file that generated the error. Example:

   <%@ Page Language="C#" Debug="true" %>

or:

2) Add the following section to the configuration file of your application:

<configuration>
    <system.web>
        <compilation debug="true"/>
    </system.web>
</configuration>


Note that this second technique will cause all files within a given
application to be compiled in debug mode. The first technique will
cause only that particular file to be compiled in debug mode.

Important:
Running applications in debug mode does incur a memory/performance
overhead. You should make sure that an application has debugging
disabled before deploying into production scenario.
