Navigation within a frame using a button : Silverlight

Question

 Hello everyone, 

I am new to Silverlight and C#. Im trying to use a hyperlink to call a page into a frame. Within the same frame, i want to use a button (which is outside the frame) to call another page.

its something like this:

        |------------------------------------------------|
        |     |------------------------|   |  hyperlink1 |
        |     |                              |   |                  |
        |     |       page a             |   |  hyperlink2 |
        |     |                              |   |                  |
        |     |------------------------|   |                  |
        |        backbutton nextbutton                    |
        |------------------------------------------------|

as seen above, there will be several hyperlinks and each hyperlinks have several pages in it. I want the page a to change into page b when i click nextbutton. When i click the nextbutton again, page b --> page c and so on.

How can i do this??? can help me please......its so urgent and important 4me. PLEASE HELP ME.....................
