Thank you so much your answer is very helpful. Here is the sum up
1. am sure that "_area" is not null, nevertheless I tried your suggestion and its the same issue
2. Your link was especially useful:
MIKEAL:
Overall, I recommend anyone to think twice before using the LongListSelector. The grouping-functionality is nice but in my humble opinion it’s not worth the problems the control causes.
3. There are some suggestion on codeplex I'll try them out

By the way you have been very helpful

Thank you
I recieve a null reference after press the back button, within the OnNavigateTo overrriden method. Specifically, the last line. I ravelled by the fact that this error is not there when the page is created initially, but if I try to navigate back to it, after leaving the page, it gives this error. This error does not occur if I don't override the OnNavigateTo Method OR if I just merely use the ListBox, but I just feel the ListBox is too ordinary.

I'll try to update my question with details of the error. You check it out, Please.

The null reference occurs at the OnNavigateTo Method override (shown in the question), when I press the back button. What mavels me is that it does raise this exception on the initial creation of the page but when I navigate away from the page and I try to go "back" to the page with the back button it gives null reference. I am trying to display heirarchical data.
A simple switching of the control to ListBox just solves, but I feel ListBox is too Ordinary.

Thank you

@Parwej Ahamad: I am quite sure the port number is correct. I am using ASP.NET Development Server and each time I run my WP7 app I check to make sure it is still run at "ASP.NET Development Server - Port 3808".
