Request.Form error in



We have a web page that displays dated notes kept in SQL table. The users
have apparently done a copy/paste of email content into the nvarchar(max)
column. Now, when we read it in edit on a web form we are getting the error
below. Can anyone help us avoid this issue as the web page crashes. Thanks.

An unhandled exception occurred:
Message: A potentially dangerous Request.Form value was detected from the
client (ctl00$ContentMain$fvActivityHistory$txtActivityNotes="...g, Teresa
<[email protected]> w...").
