Forward	The forward navigation is performed.
Itself	The navigation is performed to an identical URI source or content.
New	New navigation is performed.

Remarks

UXFrame provides an advanced mechanism to automatically detect the direction of the current navigation process. Called AutoDetectNavigationDirection, this feature makes it easy for you to determine the position of the target destination relative to the current navigation position, which enables you to perform certain actions based on the navigation direction. There are five type of NavigationDirection member that can be use, such as: Back, Forward, Itself, New and Unknown.

For more information, see Navigation Overview.

Example

The following example shows how to enable automatic navigation direction feature.

XAML

<Intersoft:UXFrame Name="ContentFrame"
                   EnablePageTransition="True"
                   AutoDetectNavigationDirection="True">
</Intersoft:UXFrame>

Once the feature is enabled, you can obtain the information of the navigation directions in the event data of the Navigating event, which is shown in the following example.

void ContentFrame_Navigating(object sender, NavigatingCancelEventArgs e)
{
    if ((e.FragmentNavigationDirection & FragmentNavigationDirection.Child) == FragmentNavigationDirection.Child)
    {
        if (e.UserNavigationDirection == NavigationDirection.New)
        {
            // do something
        }
    }
}
