Remarks

The ViewStateEncryptionMode property cannot be set in code. It can only be set in the @ Page directive or in the < element of the configuration file. Values set in the @ Page directive override any values set in the configuration file.

The syntax for setting this property in the @ Page directive is as follows:

<%@ Page Language="VB" ViewStateEncryptionMode="Always" %>  

<%@ Page Language="C#" ViewStateEncryptionMode="Always" %>

The syntax for setting this property in the configuration file is as follows:

<system.web>  
  <pages viewStateEncryptionMode="Always" />  
</system.web>  

<system.web>  
  <pages viewStateEncryptionMode="Always" />  
</system.web>

Custom control developers may wish to check the value of this property in code before saving potentially sensitive data to view state in their control.
