My engine is Aspx.

How can I decode/encode the html tags that is in my text box. I have the html tag
to make it more readable. I tried the ValidationRequest and the htmlDecode(freqQuestion.Answer) but no luck. I just keep getting the same message.

Server Error in '/Administrator' Application.

Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. To allow pages to override application request validation settings, set the requestValidationMode attribute in the httpRuntime configuration section to requestValidationMode="2.0". Example: . After setting this value, you can then disable request validation by setting validateRequest="false" in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case. For more information, see http://go.microsoft.com/fwlink/?LinkId=153133.
