I'm using TableAdapterManager to update relational data. when i insert a master row then insert some child rows and then press update, the following exception occure on UpdateAll method :

Concurrency violation: the UpdateCommand affected 0 of the expected 1 records

i know solution of this problem is handle BindingSource.AddingNew event of child table, if i using BindingSource (see this link: http://msdn.microsoft.com/en-us/library/bb384432.aspx[^]), but i don't use BindingSource and my problem is that how to solve this issue without BindingSource ?
Thanks
