NavigationService.GetNavigationService Returning Null

[Bill Kempf]

Arghhh. Can I say again, I hate WPF navigation.

I've got this "little" issue. I've got a Window, which contains a
Frame, which in turn has been navigated to a Page initially through
the Source property. A couple of other pages have been navigated to
through the use of
NavigationService.GetNavigationService(page).Navigate(uri). One such
page when navigated to tries to get the NavigationService in a Loaded
event handler, and at this point
NavigationService.GetNavigationService(page) returns null! I don't
know how this could be, and I'm not at all sure how to go about
figuring out why? Anyone got any suggestions?

Which means rolling your own navigation since WinForms doesn't have
anything built-in. In that case, I'd be better off rolling my own in
WPF. Which, in fact, I would be! But, unfortunately, neither is an
option.

Bill have you had a chance to check out nRoute? It's pretty incredible! From what I'm reading there are several cases that causes NavigationService to return empty, none of them appear to apply to you. Rather than using the GetNavigationService method have you tried the Page.NavigationService property? Doubt it'd make a difference though.

[Bill Kempf]

Where I'm at, there's no guarantee I'll have a Page, but I can try and
special case that. Like you, though, I doubt it will make much
difference.

No, I haven't looked hard at nRoute yet, but I don't think that's any
more an option for me now than rolling my own navigation framework.
Too much code reliant on the WPF navigation services.

Argh. Never mind folks. This one was my stupidity.
