MVP : How to deal with with Complex Data?

In MVP : If we have Hierarchical data model such as "Folder Structure" where does the logic for binding will occour. In View or in Presenter.

What data type is best represented to capture Hierarchical data model?

What all member does IView will have? If it is binding data (supervising)? If not the what methods presenter will have (passive)?

We have TreeControl in WinForm to representer such Hierarchical data model, if we use third party control we might not have "Node" concept. In such scenario having logic in Presenter will render presenter useless if we change View from WinForm to Webform. becuase we might have tightly coupled View (TreeView control logic) in Presenter.

I think, you create the DTO which represent your hierarchichy and presenter will process this to pass in view.

There is nothing more from SQL Express 2005 on my system, only 2008. In the Control-Panel's Uninstall program I see only Microsoft SQL Server 2008 (64-bit), Browser, Native Client, Setup Support Files, and VSS Writer, eg. 5 entries.

What I would do is uninstall sql express 2005 and install sql express 2008. That's what I had to do.

In any case the basic error is always "Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed."
