Problem in child object

Sundar posted on Friday, September 06, 2013

Hi All,

I'm very new for CSLA.NET. Can anyone suggest me how can I handle this scenario?

I have OrderMaster root object and 2 child objects OrderDetails and OrderAddress in web form. I can create/Update the OrderMaster and OrderAddress because 1 to 1 relationship. OrderDetail is 1 to many. when I test the orderDetail i can update but I couldn't insert the transaction.

I would appreciate if anyone suggest me how can I implement above scenario. Thank you.

Normally your grid control would call AddNew on the collection, assuming you bound the grid to the Order.OrderDetails collection.  If you're adding the new line item some other way, it might be that its not being added to the collection.  If you post some code showing your OrderMaster and OrderDetails that might help.
