NavigationService.CanGoForward Property

Gets a value that indicates whether there is at least one entry in the forward navigation history.

Namespace:  System.Windows.Navigation
Assembly:  System.Windows.Controls.Navigation (in System.Windows.Controls.Navigation.dll)

public bool CanGoForward { get; }

Property Value

Type: System.Boolean
true if there is at least one entry in the forward navigation history; otherwise, false.

The GoForward method throws an InvalidOperationException exception if there are no entries in the forward navigation history. To determine whether there is at least one entry in the forward navigation history, check the value of the CanGoForward property.

The following example shows buttons within a Silverlight page that allow forward and back navigation. The page uses the NavigationService property of the Page class to access the navigation service used by the hosting frame.


private void BackNavButton_Click(object sender, RoutedEventArgs e)
{
    if (NavigationService.CanGoBack)
    {
        NavigationService.GoBack();
    }
}

private void ForwardNavButton_Click(object sender, RoutedEventArgs e)
{
    if (NavigationService.CanGoForward)
    {
        NavigationService.GoForward();
    }
}
