Google Chrome Error when clicking on a regular .Net image button control inside of a GridTemplateColumn (works in IE & FF)

[Greg]

Like I said, it seems to work fine in IE and FF, but crashes in Chrome (weird). I have two image buttons inside of a GridTemplateColumn and when they are clicked, in chrome, I get the following error (detailed screenshot attached): 

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.

Hi Greg,

We are unable to identify the cause of this issue from the screen shot you provided. This seems to be a server exception not related to any particular browser. You shouldn't be getting it only in Chrome, unless, for example, you are disabling AJAX in Chrome and the stack trace pops up in Chrome and not in other browsers. In any case, if you can provide us with some test page or a sample runnable project we can debug locally, we might be able to better identify the cause of this issue.

All the best,
