How to Connect Presentation Layer to DataEntity Tier without WCF

Question

4.00/5 (1 vote)

I want to follow the procedure at:

http://msdn.microsoft.com/en-us/library/bb384570.aspx[^]

but the client has told me not to use a WCF service in between the Data Entity Layer and the Presentation Tier. Nor a web service or any service of any kind. So I put in a Class Library instead.

Or should I plop down a DataGridView on my form that's linked directly to the DataEntityTier somehow?

I've already tried putting together a class library to serve as the go-between and using it as an Object Data Source. The BindingNavigator works OK but the gridview won't populate.

Solution 2

For such case an MVP[^] pattern is quite good.

Solution 1

Take a look at How to: Bind Objects to Windows Form Controls[^] - no need to put anything between. If you want to use DataSet, DataTable and adapters, I think it's better to just stick with the "old" Fill way of doing things.

An aternative is to use something like:Database Helper v 2.0.0[^]
