Hello Karl,

The messaging display is coming from server/database as default. You could not change it. 
FYI, you only can change the error message if there are an unusual error that came because of server response failure. For this error, you can change the text in UnhandledError clientside events.

I had auto Incrementing ID fields so I had to write custom insert methods anyway that retreive the Identity values.  I simply caught the  sql exception  there  and checked if it was a unique key constraint violation and if it was i threw a new exception with a more generic and user firendly message.

When you handle identity incorrectly, it will return error exception. Please try to handle your select identity correctly.

Thanks Handy,

 Though I may have muddied the waters by mentioning identity.  The problem is not with identity insert but rather with vioalting a unique or primary key constraint, for example if you have a unique constraint on some kind of name column and a user tried to insert a duplicate. This will cause the db constraint violation exception to flow to the user, the only way of stopping it is to wright your own Insert method and explicity catch the exception and throw your own message instead.

thanks,

Karl
