A potentially dangerous Request.Form value was detected from the client

Posted by Aamir Hasan on Tuesday, July 5, 2011 Total Views:

Serval times this error has been discussed by me, so i decided to share with you. To resolve this issue you have to modify few changes in your web sites to fix this issue.

Here’s is the solution

Open your Web.Config file.
Add <httpRuntime requestValidationMode="2.0" /> under <system.web>
Add <pages validateRequest="false">

You can see the changes in Web.Config as shown.

Note: You can also add validateRequest="false" in your page on the top of the page directive for that page only.

If you have an alternative solution you can comments below.
