Navigation frame, how to set its source

06-29-2009 3:19 AM |

Hi

I have one UserControl- 'MainPage'. MainPage contains a navigation:frame 'frm_Navigation' I don't have a source in my xaml code so the first time the Mainpage is displayd, the 'content area' is empty. I also have a treeview in mainpage which I use for navigation, this displays different pages in frm_Navigation. This works fine.

 What I now need to accomplish is that the content in navigation:frame must display different pages from time to time when its first initialized (the user should not need to click in the treeview). I need a method in my mainpage.cs that checks certain criteria and then displays the correct page in navigation:frame.

 I don't know how to accomplish this, I tried to simple run navigate

Did you put the uri as absolute or relative?

this.Frame.Navigate(new Uri(goToPage, UriKind.Relative));

I tried both

Relative is the one I use when the user clicks in the navigation menu. But in this scenario it throws  a null exception.

I tried absolute as well, wont work.
