Hello
I got this exception System.Web.HttpRequestValidationException.
I am using textbox to retrieve data from dataset then edit it. Then when update button is clicked it updates database but I got this error.

What is this??


A potentially dangerous Request.Form value was detected from the client (txtPara1="....NET IDE. <br><br> At this mee...").
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. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case.

hi,
in studio.net 2003 because Microsoft change its security therefore every textbox will checked automatically and if unusual character is there it will show this exception. if you want never .net check your textbox at that specified page, just add this line in header of page
<%@ Page Language="vb" AutoEventWireup="false" ValidateRequest="false" ...
after that ur problem will be solved.

if I were you I could try other ways except ValidateRequest="false"
maybe some changing in your code could solve your problem ....
(why at all you have a <br> tag in the Text property of the TextBox!?)
