>When I got this error, I was not using a grid to add the record. I did have a grid on one tab for locating a desired record and a separate tab for entering and editing data but I was not adding records directly to the grid. I don't know if that makes a difference or not.

I must have got this mixed up with your other post. What are the controls you are using? Can you send me a screenshot of the error message?

>>>Yes, that's exactly the error I was getting. I had put a break point at the beginning of the checkruleshook but never got there. I'm not sure where to put the breakpoint on the save button because I think all this code fires before the click method. I'll have to dig around to figure out something. I guess I can put a breakpoint somewhere in the mmBusinessObject. Thanks.

>>>>What I did was open the jump start windows application and in an existing order I clicked new on the OrderDetail grid. I tried to add a new record with the same OrderId and ProductId of an existing detail. This brings up an error message (ugly) that says a constraint is being violated. I am wondering if this is the same type message you are getting? I was going to use this as a starting point to try to replcate what you are doing.
