I have started using Presentation Model w/ ASP.NET webforms and like the pattern quite a bit. What I am really having an issue with is where to instantiate some of my classes, mostly the presentation model, my business object, and things like the data for drop down lists. So I could use some tips or a complete example of the Presentation...
At my current job we have a CMS system that is .NET/SQL Server based. While customizing a couple of the modules for some internal use, I was a little surprised to see that instead of having APIs that returned data via your typical result set that was bound to a DataGrid/DataList/Repeater control, that the APIs returned an XML node/collec...

What I'm trying to achieve: I currently have a view displaying non-editable information about a domain object called Node. Depending on if the Node is editable and the user has the right privileges, an additional view becomes available whe...

All the examples I can find are simple, flat data entities with no 1-many or many-many relationships, which are what I can't get working - specifically, on updates and inserts into associative relationships. Queries I can get working fine - I have my presen...
I'm sharing data via RIA services using a presentation model on top of LINQ to SQL classes. On the Silverlight client, I created a couple of new entities (album and artist), associated them with each other (by either adding the album to the artist's album collection, or setting the Artist property on the album - either one works), added ...
I am trying to prepare myself for being challenged with the question: "Why cant we just implement the presentation model in the code behind?" In fact I have worked on a project where we used a Presentation Model that was implemented in the code behind. It worked fairly well, we were even able to run unit tests on it. Yes you have a dep...

I enter a task name in a text box, click on the add task button, and expect the list to be updated with the new item and the task name input to be cleared. I only want to be able to add tasks if the task name is not...

An easy example with be a view with 3 buttons and 7 textboxes, all having value, enabled and visible properties exposed from the view. Adding validation results for this, and you could easily end up with an interf...

I'm re-working a Winforms application and would like to employ a variation of the Presentation Model pattern for the UI. Could someone tell me from the following explanations if I'm doing it correctly? I have decided to set up dependencies as follows: Model <---- Presentation Model <---- View That is: The model is not aware of...
I'm working on a 2-tier application where WinForms client makes direct calls to the database. In one of the scenarios I need to display a list of Customer entities to a user. The problem is that Customer entity contains a lot of properties (some quite heavy) and I need only two of them - first and last names. So to improve performance an...
