Server Error in '/' Application.
A potentially dangerous Request.Form value was detected from the client (txtCode="<br/>").
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.
