In the sample code you sent I saw the following error:
In your XAML class:
This means that the namespace is : PageNavTestBench and the class is Page1.
However, in the code-behind you have :
public partial class Page1 : RadPage
The namespace is different : TelerikTest2 !
In order to compile the code and Initialize the page there should be no difference between the namespace in the XAML and the code-behind. You should correct this and the code will compile.
