I have 3 tables "deal", "address" and "property":
table "property" is child of both "deal" and "address".
Then I use Entity Framework to create entities from database.
I also build the 3 BO inheriting BusinessBase.
Windows form has some controls databinds to the corresponding datasource, but when I save a change, i get error:"Edit level mismatch in AcceptChanges".
Can someone tell me what the problem is? Thanks.
You must bind/unbind BO and BindingSources properly.
You may read my blogpost here: http://jonnybekkum.wordpress.com/2009/10/20/forms-databinding-the-magic-sequence-of-binduiunbindui/
And I also recommend to read the DataBinding FAQ at http://windowsclient.net/downloads/folders/applications/entry1302.aspx
