Invalid postback or callback argument

Hi, 

I have a website and having a default page. In Default.aspx page, on top right corner, have a hyperlink button named 'SignIn'.

On click of 'SingIn' hyperlink button, I am redirected to SignIn.aspx page where user has to login. For the whole website, I have a Master page and using ScriptManager tag.

On click of SignIn hyperlink button, the page is redirected to SignIn.aspx page. While redirecting, rarely this page is throwing the below error message.

Exception information: 
    Exception type: ArgumentException 
    Exception message: 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. 

I am not clear whether set EnablePartialRendering to true or not. 

Please let us know, what I need to do the changes ? 

Thanks in advance.

Regards,
Sriram
