    ValidateRequest="false" error

    After I set my <%@ page ValidateRequest ="false" %> , I still get the
    error illustrated below. The msdn mentioned something about filtering
    using the HTMLEncode. This is a snippet of the code that should display
    the result.

    Server Error in 'name of app' Application.
    ------------------------------------------------------------------------
    --------

    A potentially dangerous Request.Form value was detected from the client
    (RevisionHistor yTable=" <TABLE border=1 styl...").
    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. You can 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.
