UXNavigationWindow offers modularity concept by creating each steps of the wizard in a single UXPage. Developer can easily find a step; modify a specific step without having to worry that the changes will affect the other steps.

In order to create simple wizard in a single UXPage, you may try to create each step in a StackPanel. Step 1 in StackPanel1, Step 2 in StackPanel2, and so on. On initial loaded, set the Visibility property ot StackPanel1 to Visible and other StackPanel(s) to Collapsed. And when user presses Next button, set the corresponding StackPanel to Visible and other StackPanel(s) to Collapsed.
