Error:A potentially dangerous Request.Form value was detected from the client-- Allowing JavaScript to be submitted

We have a site were trusted users can add some Javascript tracking code into a text box for submitting, so naturally we have turned off Validation by adding the ValidateRequest="false" into the Page Directive.

However it we seem to be getting the error again all of a sudden : A potentially dangerous Request.Form value was detected from the client , Now we cant add ValidateRequest="false" into the Config or the Master page this page inherits from. So how do I allow Javascript to be posted, what is overridding the ValidateRequest?

We are using .Net 3.5

Solution

  • Probably something else, not the Page, is triggering the error due to the breaking changes made in the framework.. if you can't edit the web.config I fear you're pretty much stuck.
