Check out the third of 8 videos by Ken Cox about the development of CRUD application using Silverlight and Visual Basic.NET.

In Episode 3 of my series on creating a Silverlight 2 Data Form, we display the details of the selected item and explore the DataContext property. I spend some time on the interesting and flexible ObservableCollection objects and configure automatic UI updating by implementing INotifyPropertyChanged.

Note: The previous episodes are prerequisites: Episode 1, Episode 2

Sometimes the video might not be available because of some internal problems of the Silverlight streaming services. Please excuse us for the inconvience, we hope that this problem will be fixed very soon.


The full source code is available for download from here.

    Hi Ken,

    I found something different on my program which was written based on yours. At the end of your video you wrote a method named 'OnCompanyNameChanged' and declared it to private, right? However, when I declared this method to private, an error occurred. It said 'Type Customer already defines a member called OnCompanyNameChanged with the same parameter types'. It's right, I found the method with the same name and the same parameter types in file Reference.cs. But luckily, when I changed the declaration of this method to 'partial', it worked.

    So I wondered if it had something different between C# and VB in this situation as I wrote the program in C#.

    I'm looking forward to your reply.
