Not answered RadControlsSilverlightCourseware.PDF code missing and incorrect

I have just coded up a drag and drop walkthrough in the courseware pdf document. Immediately it becomes evident that code is missing and obviously the project wont compile. This is just like the approach Microsoft take. They test very little and wait for the complaints to role in... ie: free testers. Is Telerik following this example?

I am using Silverlight 4; Windows 7.

No Problem..
I have deleted the project now so this will be from memory:

Page 759: Document doesnt specify that the dragDrop xaml namespace should be included and an error is thrown.

<ListBox.ItemContainerStyle>

<Style TargetType="ListBoxItem">

<Setter

Property="dragDrop:RadDragAndDropManager.AllowDrag"

Value="True" />

</Style>

</ListBox.ItemContainerStyle>

Page 761/ 766: On page 766, when you run the application you get an error because at this point the code on page 761 had not yet been implemented:

RadDragAndDropManager.AddDragQueryHandler(this, OnDragQuery);

RadDragAndDropManager.AddDropQueryHandler(this, OnDropQuery);

Also , I have been looking at the ScheduleView, this time on the help webite. When trying to show a basic Scheduler View, an error is thrown by the ViewDefnitions. I have not been able to find references to building a SchedulerView in the documentation.

Could you tell me if Telerik intends to keep the Courseware in sync with the examples on the help website? If not, where can one find walk through type tutorials (as in the Courseware PDF) on this and other controls?

Hey Nick,
I'm working my way through this doc too and have found quite a few places where you have updated your code but not the training. Mostly working out these differences has resulted in more learning but now I am quite stuck.
Here are the ones I can remember:
1. p.114 ADO.NET Data Service has been called WCF Data Service since 2009 - took me quite a while to work this out.
2. p.117 'DataMemberPath' is not just deprecated but deleted - code won't compile. Need to use DataMemberBinding="{Binding FirstName}" etc.
3. p.120 Query_Completed method fails due to cross-threading. Need to use:

gvAddressBook.Dispatcher.BeginInvoke(() =>

            {

                gvAddressBook.ItemsSource = addressBook.ToList();

            });

4. p.121 OpenAccess - this entire section is based on the old OpenAccess. I don't want to learn how it was done. I just want to know how it is done now! I can't complete this section at all so ironically, the one datasource I can't use it the Telerik one. ;(

Can you give me updated text for this section?

So this is as far as I have got as yet. You can see there are quite a few major errors which slow down the learning experience.

But... I've got to say too that I have learned heaps from your tutorials. I am finding the level of detail and the general overview to be just about right.
