For : VS 2008, C#, Windows 7, framework 3.5, Windows forms.
I creating a program, that on some occasions needs to retrieve data from database.
After the main screen retrieve the data, I want to expends the data, and make only the changes made by the expended screen to the database.
Also there are more inner screen (the expended screen expends a new one).
The whole process should commit at the first screen (as one transaction - changes are only in memory, till I do commit).
What is the best attitude doing the above.
I have tried putting two bindingSource with two dataSources, but it's a guess, which didn't work well.
I need an example for that, please.
