When signing in using the following generated password:

+$cSB;!"q<y^I recieve the following error:A potentially dangerous Request.Form value was detected from the client (ctl00$cphContent$txtPassword="+$cSB;!"q<y^").System.Web.HttpRequestValidationException


What characters am I allowed to include in a value that will be generated and submitted in a TextBox? When I generate something simple (such as "testing" or "abc123") it gets submitted with no problem at all, so I need to know what characters will cause this problem so that I can modify my function for generating the String. Can anyone help me? Thanks.
 
depends on if you have validate request on (default). if you do then
asp.net is checking for injection attacks. ms does not document the list
but it "<" & "&#" combinations (probably also quotes). the list gets
updated as new attacks are found.
