My UWP app uses the MvvmCross framework and has a NavigationView with a main and a detail page, as you can see in the illustration and folder structure. Content ] to display them on the content side. Now I want to add a working back button on the detail view, but I do not know how to enable the button and navigate back.

NavigationView has a built-in back buttonyou could set IsBackEnabled as True to display it and subscribe the BackRequested event to control the navigate back operation in it. By checking the code, the page isn't loaded in the FrameContent, the NavigationView has it build-in Frame, so you can use the VisualTreeHelper to get the Frame by referring to this thread.

In this article, I will show you how to use the Navigation View to show your content and navigate between pages. To add navigation items, you should use its MenuItems property. For example, when you use this code:. You need to add an icon to the items. This is done with the Icon property. You can set it directly using an enumeration for the symbol see all enumerations here or you can set the icon from an image. This code shows how this is done:. ItemInvoked is called when an item is selected by a user interaction tap, pointer, mouseand it can be called even if the item is already selected.

In the handler, you have to find out which is the item selected and take the according action, usually changing the content of the control. This code shows how to handle this:. We are checking the selected item, if it is a different one, we create a grid with a textblock that shows the text of the selected option and set it as the content for the NavigationView. We could manage the content and navigation by ourselves. In this case, we would need a navigation mechanism, that handles the back navigation and replaces the content in the NavigationView.

But we can do it by adding a single control: the Frame. It can control the back navigation and even replace the content with a transition. This can be done with something like this:.

In our case, we will store an unique string that will point to the view, so we can navigate to it. Our code will be something like this:. Now, we must create the views for each item.

If you run the program, you will see something like this when you click an item:. This code has one problem: if you click the Settings item, you will get an error. If the tag is null, we will navigate to the SettingsView. With this change, the code works fine and you can click on the Settings item. There is only one thing that can be made, here: manage when the back button is clicked. We do this in the BackRequested handler:. As you can see, the NavigationView allows you to create easily a responsive UI, with lots of features and many different ways to handle navigation.

But it seems to have " acrylic " that I can not remove, as well as changing the background color of the Header. You would generally modify these two resources to customize the appearance of the Acrylic Brush, by overriding them the following way:.

No need to over complicate anything. You already have your ViewModel referenced in your code-behind in order to use x:Bind, so I can't think of any reason whatsoever why you can't just use the code-behind event handlers. This does not violate MVVM, not even a little.
