Very very god work all the pieces are starting to come together.

I don't understand way you aren't using unity to discover the ViewModel for the View's

Another question - can helix play nice with prism?

Thanks for the feedback mhnyborg.

Yes, I could certainly have used the Dependency Injection pattern and Unity to hook-up the View and ViewModel. There are a couple of things with that model I don't like but it's certainly do-able. I'll put together a post on that and explore the options.

I'm already using some Prism features in Helix - namely the DelegateCommand stuff - so they coexist side-by-side pretty nicely. There are some Prism features like modularity and regions that can really tie into Helix more deeply. I'm working on a blog post to show that too.

Thanks for your work on Helix and the CollectionViewModel. Pretty awesome !

I implemented the CollectionViewModel code for a datagrid. I noticed I get an error when I select a row in the grid and then sort on any column by clicking on the header. The count of the CollectionViewModel object seems to become zero. I fixed this simply by putting in a check condition for the count. There may be some better solutions I'm not aware of which could fix the same issue.

Regards,

@winrunner - Thanks for your feedback, and thanks for calling the DataGrid issue out. I'll take a look at that and see if I can see what's going on.

I've noticed that the DataGrid behaves differently when bound to an ICollectionView than other controls. I thought I'd accounted for these differences but it looks like I need to take a more careful look...

Hi David.

Are there some ways to integrate your Navigation framework with Navigation framework that comes from Silverlight 3.0 beta 1?

Could you please to write some thoughts about it?

Sorry for English.

I am interested in your thoughts on Erchan's thoughts, as well as your reason for creating your own route handler. Was the ASP.NET MVC route handler not sufficient or not a workable solution?

@Erchan - Yes, I'm working on a post to talk about navigation in SL3 & Helix. There are some similarities between SL3 navigation and Helix, but there are limitations with SL3 due to the lack of extensibility points... I'll keep you posted.

@riles01 - I would have loved to have used the ASP.NET Routing engine. Unfortunately, there are a couple of things that prevented me from doing so. First, it's a full .NET Framework assembly so won't work in Silverlight. Second, it's really designed for ASP.NET so it has some dependencies on specific web classes, like HttpContext, etc.
