How to hide the navigation bar in a WPF page

问题:

I want to hide the navigation bar in a page created using WPF. I have tried ShowsNavigationUI = false, but it is still displaying the control.

回答1:

Setting ShowsNavigationUI=false on a Page object ought to do it. There does seem to be a bug, however, that will cause this to fail in at least one sequence of events:

1. Page is already in NavigationWindow when this is set
2. Page is navigated away and back again

There may be other scenarios I haven't run into yet that make it fail.

To get this to work totally reliably, what I do is ignore the Page.ShowsNavigationUI property entirely and set it instead on NavigationWindow. This seems to be completely reliable.

Here is how this can be done in your Page constructor:

Dispatcher.BeginInvoke(ApplicationPriority.Render, new Action(() =>
{
  var navWindow = Window.GetWindow(this) as NavigationWindow;
  if(navWindow!=null) navWindow.ShowsNavigationUI = false;
}));

If you do this, remember not to set ShowsNavigationUI on any Page object.

FYI, you can also restyle your NavigationWindow any way you like by changing its ControlTemplate. For example this removes everything but the actual page content:

  <Style TargetType="{x:Type NavigationWindow}">
    <Setter Property="Template">
      <Setter.Value>
        <ControlTemplate TargetType="{x:Type NavigationWindow}">

          <AdornerDecorator>
            <ContentPresenter Name="PART_NavWinCP" 
                              ClipToBounds="true"/>
          </AdornerDecorator>

        </ControlTemplate>
      </Setter.Value>
    </Setter>
  </Style>

just tell in Your page Container , you want navigation bar or not, using NavigationUIVisibility property.

<Frame Margin="173,41,1,28" Name="frmPageContainer" NavigationUIVisibility="Hidden" Panel.ZIndex="1" >

It's a very easy implementation.

<Frame x:Name="_FrameName" NavigationUIVisibility="Hidden" />

If you're using a Frame you can change the Frame's default style to remove the navigation buttons (shown below). The same approach could be done for NavigationWindow. I originally tried setting Page.ShowsNavigationUI and it had no effect. Just add the below style to a ResourceDictionary and it works fine.

<Style TargetType="{x:Type Frame}">
  <Setter Property="Control.Template">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type Frame}">
        <Border BorderThickness="{TemplateBinding Border.BorderThickness}" Padding="{TemplateBinding Control.Padding}" BorderBrush="{TemplateBinding Border.BorderBrush}" Background="{TemplateBinding Panel.Background}">
          <ContentPresenter Content="{TemplateBinding ContentControl.Content}" ContentTemplate="{TemplateBinding ContentControl.ContentTemplate}" ContentStringFormat="{TemplateBinding ContentControl.ContentStringFormat}" Name="PART_FrameCP" />
        </Border>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>

This one I found really easy. In your MainWindow, do this:

public MainWindow()
   public partial class MainWindow : NavigationWindow
    {
        public MainWindow()
        {
            InitializeComponent();

            ShowsNavigationUI = false;
        }
    }
}

And if you have an event on button click to open a new page, just do this:

private void btnEndUserSearch_Click(object sender, RoutedEventArgs e)
{
            EndUser EndUserSearchPage = new EndUser();
            this.NavigationService.Navigate(EndUserSearchPage);
            EndUserSearchPage.ShowsNavigationUI = false;
}

Above works only for Navigation windows, but I am using ordinary WPF windows. Some say these are better than Navigation windows. I am using DockPanel to host my pages. My solution creates a new template for the DockPanel and simply does not add buttons or makes them hidden (see StackPanel Visibility="Hidden"). It works nicely.

<DockPanel>    
    <Frame x:Name="_mainFrame">
    <Frame.Template>

        <ControlTemplate TargetType="Frame">
            <DockPanel Margin="7">
                <StackPanel Visibility="Hidden"
                    Margin="0"
                    Orientation="Horizontal"
                    DockPanel.Dock="Top"
                    >
                    <!--<Button
                        Content="Avast! Go back!" 
                        Command="{x:Static NavigationCommands.BrowseBack}" 
                        IsEnabled="{TemplateBinding CanGoBack}" 
                        />
                    <Button 
                        Content="Forward you dogs!" 
                        Command="{x:Static NavigationCommands.BrowseForward}" 
                        IsEnabled="{TemplateBinding CanGoForward}" 
                        />-->
                </StackPanel>

               <Border>
                    <ContentPresenter />
               </Border>
            </DockPanel>
        </ControlTemplate>

        </Frame.Template>
    </Frame>
</DockPanel>

I had this problem whenever I dynamically changed the Content property of a Frame, and solved it by using the following code in my click() event.

ContentFrame.NavigationUIVisibility = NavigationUIVisibility.Hidden;

Where ContentFrame is the name of the frame, as defined in XAML. i.e.

<Frame x:Name="ContentFrame"  />

On the NavigationWindow itself I use ShowsNavigationUI="False"
