Frame.CanGoBack Property

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

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

public bool CanGoBack { get; internal set; }

Property Value

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

Dependency property identifier field: CanGoBackProperty

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

The following example shows event handler code for buttons on a frame that allow forward and back navigation.


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

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