I am trying to generate CheckAccessHelper with the check boxes "Allow Role Check Access", "Allow Task Check Access" using the web console(hosted in my pc), and i am getting th following error:

A potentially dangerous Request.Form value was detected from the client (ctl00$ContentPlaceHolder1$txtSourceCode="...-----
// <auto-generated>

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: <httpRuntime requestValidationMode="2.0" />. After setting this value, you can then disable request validation by setting validateRequest="false" in the Page directive or in the <pages> configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case. For more information, see

Exception Details: System.Web.HttpRequestValidationException: A potentially dangerous Request.Form value was detected from the client (ctl00$ContentPlaceHolder1$txtSourceCode="...-----
// <auto-generated>



Can you tell me how to fix that?

try to add the validateRequest="false" into the @page directive of the dlgGenerateCheckAccessHelper.aspx page.

Anyway … generate the CheckAccessHelper class with the MMC console and try to see if there are some tag like <…> or something strange (application / item description) ?
