It is not possible to disable the event validation only for a certain page. The EnableEventValidation property is set after the page is initialized. You cannot set the EnableEventValidation property in code of a control. You could bypass validation for a specific ASP.NET Server control by setting the control's CausesValidation property to false. Disabling event validation could result in the way that the postback could be constructed and this could have an unintended effect. If this does not help, you could use an external ASP.NET web page which is located in your project and you will use it with your form. This will allow you to set the enabledEventValidation attribute of the @ Page
