Great videos!

I tried downloading Part 1-10 in iPod format. It seems that they are all copies of Part 1 :/

Really a wonderful set of videos.  I'm on the other side of the world in Hawaii.

I am also having Part 10 give me a media error about 85% of the way through.

Thanks!

At around 30 minues you go and create your own commands for ListBoxSelectionChanged and TreeViewSelectionChanged - what are your opinions on using, for example, a TwoWay Binding to the ListBox SelectedItem property to the view model instead and then publish the event in the Setter?  Not such a nice solution perhaps but possibly easier in many of these cases.  Here's what I did for the MailListViewModel which seems to work fine:

Adding a binding as follows:

<ListBox SelectedItem="{Binding SelectedItem, Mode=TwoWay}"
 ScrollViewer.HorizontalScrollBarVisibility="Hidden" 
ItemsSource="{Binding Emails}">

Then had the following property on the view model:

private object _selectedItem=null; 
public object SelectedItem { 
   get { return _selectedItem; } 
   set { 
        _selectedItem = value; 
        EmailSelectionChangedEvent evt = eventAggregator.GetEvent<EmailSelectionChangedEvent>();

        MailViewModel viewModel = (MailViewModel)value; 
        evt.Publish(viewModel == null ? null : viewModel.Email); 
       } 
}

Can you see any problems with this approach?

Fantastic set of videos by the way - really detailed and incredibly useful - many thanks for the work you have put into them; I for one really appreciate the hands-on "live code" approach that you take...

Cheers

Nice to hear from you ( and see you briefly at the StackOverflow day the other week ). I agree that creating the custom command here did a feel bit heavy handed as it's quite a lot of code for what you get out of it although it does keep that separation very "pure". Someone dropped me a mail saying "What if I used Expression's behavior library for that?" which seemed like another approach and you have another one here  which seems pretty reasonable to me ( and a lot less code ).

Thanks,

Mike.

Bravo!

Is it possible to have the code source from all samples, like you did for the last sample?

(In order to play with).

It's very easy to learn Prism with your screencasts. Thank you very much.

Do you plan to add a part 11, about the topic unit testing? Currently, I'm not sure how to unit tests the different assemblies from the email client. Do I need a bootstrapper in my unit test method and the region manager stuff to get it run for the unit testing?

Thanks in advance,

           I have gone through the video you have mentioned.

           Although many doubt regarding EventAggregator, UnityContainer, RegionManager where solved. But I am failed to get a Answer Regarding:

        In my project I have  to Navigate as if   "Shell"    conatin two region ToolBar +( (Common Module(LoginViews))--------> Module A or Module B or Module C)

        Here "Common Module" Can be Considered as "login module". After login the user will choose the application namely "Module A" or "Module B" or  "Module c".     Each module as number of  "sub-Module" say "View"s Expect  for "login Module" .Please help with an Idea.

       my  shell .Xaml code:

<UserControl x:Class="Forte.UI.Shell.Page"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

First of all, This is a great series post, I must say.

I am sure by now you are moved on to lot of new stuff like Silverlight 4 etc.

I have seen this series of posts and its immensely useful for someone to start getting insight into PRISM framework.

in my new project, I am trying to use PRSIM framework and want to have multi platform application.. ( that's the goal )

I was wondering, If you can post this application or parts of last series of smaller posts which shows "Test Driven Development using PRISM" , "Test first" approach.

That will give even more idea for new people trying to learn PRSIM, what to test and what not to test.

your comments are welcome.

Hope that would be possible.

Cheers.

Imagine my disappointment though when, at about 123 minutes of the last video, I got a "media failed" error ... oh well, at least I have the source code :/

Maybe the wmv or whatever could be made downloadable?

Anyways, really enjoys the series and got a lot out of it - cheers!

I followed through using VB and duplicated your efforts. It's starting to make sense for me now.

Thanks.

This one is particulary great. The presentation is really good. I hope we'll got more and more

 I am  a beginner in Silverlight & Prism. I saw this vedio and i learned some concepts. I ve ended up with few questions..

You have created many projects like "EmailEntities,EmailInterfaces,EmailService,MailListUI,MailReadingUI,MailSelectionUI,NewMailUI,

PresentationUtility,ViewInjectionImplementation,ViewInjectionInterfaces".

They are all related to UI  email functionalities. As a beginner, My questions are

1. What is presentation pattern you have used in this sample..

     Pls explain me what are all the Models , Views , Presenters stuff used in the solution.. ?

2. which class acts like a View , Model & Presenter ?

3.If at all i need to include Database stuff(reading messages from DB) , I assume i need to have 2 other projects namely domain layer, infrastructure layer. In this context,  should the Model communicates Or View communicates Or Presenter communicates with the domain layer ?

4. If i have domain & infrastructure layer, does it make sense to maintain the "PresentationUtility" project inside the infrastructure layer..?

These are my fundamental questions awaiting your esteemed reply.

Thanks

So, the next day, from work, on a different computer I was able to watch the whole video.

Maybe minor question but in all your View's you always set the DataContext in a lamda which fires on the FrameworkElement.Loaded event.

Is there a case when deferring this assignment until the Loaded event is better than just assigning immediately in the class constructor?

Start with .. and then .. wonderfull.

Now a days - Include the Wcf Ria Services with Prism - And show the last (show 10) again. Now ther is commands & behaviors.

The one I want most, is how to use it on Model first approach. It seems to me using the model first approach, dictate a wrong way to use Prism 4 and Ria services?

Is it Poco's or somthing else that is the starting point?

I think it would be a great thing if you could add videos about the other features of Prism 4.0 (navigation etc.)

Also, I wish you could extend this series so that after watched and studied, user should be able to build a robust Silverlight LoB application, using other related features of Silverlight and its relatives, such as WCF RIA Services, Entity Framework, and patters like Repository, DAL and more.
The final idea is to teach users how to create a real-life end-to-end LoB application using the most efficient available ways and technologies.

Shimmy
