Thanks, that will address the second issue.  But what about when Item.Price changes?  How would I update Order.Total in that scenario? 

If memory serves, the changed event of an Entity property only fires once, which doesn't really work how you would expect it.  So am I left to create my own event and handle this scenario manually?

Thanks again!

I also wanted to add the following scenario.  I have had no luck supporting this type of domain model pattern with WCF RIA, due to lack of supplied events.

Debug.WriteLine(Order.Total); // outputs 0

Item newItem = new Item() { Price = 30 };

Order.Items.Add(newItem);

Debug.WriteLine(Order.Total); // outputs 30

Order.Items.Remove(newItem);

Debug.WriteLine(Order.Total); // outputs 0

Thanks again!

How do you create a calculated field based on child objects?  For example, if you have an Order object that exposes a Total property based on a child Item.Price value, how can Item.Price notify Order to update its Total property (Order.Total) ?

So you would have Order.Items[1].Price = 2.25;  Then Order.Total would be updated to reflect the change made to the Item.Price property.

Thanks!

Excellent, thanks!

Bruno, does the download include the source as well? 

If not, can you briefly explain the UI composition that holds the main chart towards the middle and the 2 smaller charts to the right. 

Also, are you using any UI frameworks such as PRISM or MEF?

Thanks and nice work!

Great content, thanks! 

John, when watching the vids in full screen mode, the vs ide is always blurry.  Can you fix that in future vids?  It's terribly difficult to see the code.

Thanks!

Really great job, Mike, thanks!  I really enjoy how you dig into the framework so the average developer is educated and not blinded by the abstraction.  I really enjoy watching all of your presentations and look forward to seeing more!

I really dig what you're doing, Jesse.  Thanks for the blog posts, the code, and all of your efforts thus far!
