OK, based on your sample above; 

        <Intersoft:UriMapper>
            <Intersoft:UriMapping Uri="" MappedUri="/Views/Detail/ProductDetail.xaml"/>
            <Intersoft:UriMapping Uri="/Inventory/{page}" MappedUri="/Views/Detail/{page}.xaml"/>
        </Intersoft:UriMapper>
    </Intersoft:UXFrame.UriMapper>

 Then I add 1 UriMapping :

<Intersoft:UriMapping Uri="/Customers" MappedUri="/Views/Detail/Customer.xaml"/>

 At the first state, I set (in mainpage.xaml)

<Intersoft:UXStackItem Text="Header Name" FontSize="12"  NavigateUri="/Products"/>

In ProductDetail.xaml, i want to have a button which can change NavigateUri above to "/Customers"

Do you have any idea ?

Well, here is the simple scenario;

I use 'Intersoft ClientUI MVVM Business Application' template.. there is uxFrame inside mainpage.xaml ..
In customer.xaml, there is uxTreeView and uxFrame.

And, what  I want to do is when I click an item from uxTreeView, I want to navigate uxFrame inside Customer.xaml to the specific page.

How can I achieve this goal?
I've tried to navigate uxFrame inside customer.xaml, but the result is uxFrame inside mainpage.xaml that navigated.

Hi

I use Intersoft WebUI studio 2011 R1, when I try to use some control like video player, uxFrame, uxFlow, etc. , I got this error :
