i use cascading dropdown lists (in a user registration form) and when the user hits the submit button i get the error:
"Invalid postback or callback argument"
I've seen on the net that this is a problem dating back many years but still haven't found a solution to this.
I've read about changing EnableEventValidation to false, but this poses a security risk.
Anyone knows a good solution to this? (i'm coding in c#)
