Silverlight QueryString Validating ID, GUID and Timestamp (Date)

This post is very much a combination of my three previous posts (Silverlight QueryString using TryParse() method, Validate GUID in Silverlight – Parse GUID in C# and Extension methods in Silverlight and C#) to demonstrate all these great features in one place. I have also added an Extension method in this project to validate Date and Time using a simple Regular Expression, for better validation I suggest change the Regular Expression to match your specific needs.

I am not explaining the code for this project as each part is explained in details in the posts I mentioned above, but please do feel free to ask any questions in the comment section below and I will try to answer as soon as I can.

This project can be downloaded from CodePlex from here, and feel free to play with the working version of it below.

dev:

I have a question about SL3 PagedCollectionView and wonder if you could help. I have the following code and the data enter on 1 page and copied over to another page on the same row number. Is this a bug? is there a workaround?

PagedCollectionView pagedCollectionView = new PagedCollectionView(e.Result);
dataGridBike.ItemsSource = pagedCollectionView;
dataForm1.ItemsSource = pagedCollectionView;

// populate employee info
ObservableCollection bikes = new ObservableCollection();
//PagedCollectionView bikeView = pagedCollectionView;
bikes = (ObservableCollection)pagedCollectionView.SourceCollection;
