Silverlight page navigation?

I have three xaml pages page1.xaml, page2.xaml and page3.xaml,

1. how to navigate page1.xaml on button1 click event to Page2.xaml?
2. how to open Page3.xaml as a popup on butt开发者_Python百科on2 click event of page1.xaml?

I have seen multiple answers but not able to find any exact solution that's why I've tried here.

I am using the intersoft controls here but the same principle applys for standard buttons

Intersoft:UXNavigationButton 
        Content="View Error Log" 
        NavigateUri="/ServerSideOperation/ErrorLog" 

Your code would look something like:

Button Content="Go to Page 2" NavigateUri="/Page2" 

For the Pop Up you will need to use a child window. Google for Childwindow and check the examples.
