سلام دوستان!
من یک پروژه ای رو دارم طراحی می کنم که در آن نیاز دارم که کد html را از کاربر گرفته و یک سری تغییرات انجام بدهم و همین طور کد را در یک TextBox به نمایش بگذارم.
اما با ورود یک کد و یا نمایش دادن یک کد این خطا می آید:
Server Error in '/' Application.
A potentially dangerous Request.Form value was detected from the client (ctl00$ContentPlaceHolder1$TBXImport="<!--Code--><div alig...").
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 http://go.microsoft.com/fwlink/?LinkId=153133.
