uwp multiple pages

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I am tasked with creating a multi-page UWP app that needs to pass a student object through multiple pages. The app starts on the main page where there are two buttons, one to add a new student and then and the other to then view the students details. I am currently struggling trying to figure out how to pass the student object from the "new student page" to the "student details" page.

I'm not allowed to store the students information in a file or database. When a new student has been added the information should be stored within the Student object, is it possible to make this object public so that it can be used without passing it through pages? Is it also possible to bind the text blocks on the student details page to the student object that is from the input page?

You can use your Student class object and then pass it to another page when Navigate to it as parameter. You see… an expert developer sees the UI only as the "presentation layer" for app data, NOT as the main logic layer. The correct way to do it is creating a static entity that acts as the "engine" of the logic of your app and that is present during all the app's session.

The usual way to implement this, in fact, is by using the standard MainPage as the "shell" of the app, containing a static field named "Current" that redirects to the MainPage itself, and an AppViewModel class, that contains all the app data and logic.

Then you access the MainPage.

Navigate instead of MainPage. The code here uses the return value of Navigate to throw an app exception if the navigation to the app's initial window frame fails.

When Navigate returns truethe navigation happens. Now, build and run the app. Click the link that says "Click to go to page 2". The second page that says "Page 2" at the top should be loaded and displayed in the frame.

Before we add more functionality to our app, let's look at how the pages we added provide navigation within our app. First, a Frame called rootFrame is created for the app in the App. OnLaunched method in the App. The Navigate method is used to display content in this Frame.

By default, this method loads MainPage. In our example, Page1 is passed to the Navigate method, so the method loads Page1 in the Frame. Page1 is a subclass of the Page class. The Page class has a read-only Frame property that gets the Frame containing the Page.

When the Click event handler of the HyperlinkButton in Page1 calls this. Navigate typeof Page2the Frame displays the content of Page2. Finally, whenever a page is loaded into the frame, that page is added as a PageStackEntry to the BackStack or ForwardStack of the Frameallowing for history and backwards navigation.

Our app navigates between two pages, but it really doesn't do anything interesting yet. Often, when an app has multiple pages, the pages need to share information. Let's pass some information from the first page to the second page. In Page1. Here, we add a TextBlock label and a TextBox name for entering a text string.

In Page2.

Here, we add a TextBlock for displaying the text string passed from Page1. Run the app, type your name in the text box, and then click the link that says Click to go to page 2.

Textthe name.If you think of an app as a collection of pages, navigation describes the act of moving between pages and within a page. It's the starting point of the user experience, and it's how users find the content and features they're interested in.

It's very important, and it can be difficult to get right. While there's no single navigation design that works for every app, there are principles and guidelines to help you decide the right design for your app.

Navigation should be consistent with user expectations. Using standard controls that users are familiar with and following standard conventions for icons, location, and styling will make navigation predictable and intuitive for users. Fewer navigation items simplify decision making for users. Providing easy access to important destinations and hiding less important items will help users get where they want, faster.

Clear paths allow for logical navigation for users. Making navigation options obvious and clarifying relationships between pages should prevent users from getting lost. Now, let's take our design principles--consistency, simplicity, and clarity--and use them to come up with some general recommendations. Think about your users. Trace out typical paths they might take through your app, and for each page, think about why the user is there and where they might want to go.

Avoid deep navigation hierarchies. If you go beyond three levels of navigation, you risk stranding your user in a deep hierarchy that they will have difficulty leaving.

Avoid "pogo-sticking. Now that you're familiar with general navigation principles, how should you structure your app? There are two general structures: flat and hierarchal. You can go from one page to another in any order.

In a hierarchical structure, pages are organized into a tree-like structure. Each child page has one parent, but a parent can have one or more child pages.

To reach a child page, you travel through the parent. Hierarchical structures are good for organizing complex content that spans lots of pages. The downside is some navigation overhead: the deeper the structure, the more clicks it takes to get from page to page.

You don't have to choose one structure or the other; many well-design apps use both. An app can use flat structures for top-level pages that can be viewed in any order, and hierarchical structures for pages that have more complex relationships. If your navigation structure has multiple levels, we recommend that peer-to-peer navigation elements only link to the peers within their current subtree.

Consider the adjacent illustration, which shows a navigation structure that has two levels:. Once you've decided on a page structure, you need to decide how users navigate through those pages. UWP provides a variety of navigation controls to help ensure a consistent, reliable navigation experience in your app.

With few exceptions, any app that has multiple pages uses a frame.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I try to port some Windows Phone 8 projects to current UWP, and get stucked in this snippet code that I've used in old project. In that code, I used NavigationService to pass some parameters to another page.

My question is how to do in proper way to passing some parameters in UWP project? What you passed in Windows Phone 8 has just been a simple string that included all your parameters. You had to parse them in the OnNavigatedTo method of your target page. Of course you can still do that and pass a string to the Frame. Navigate method. But since UWP you can pass complete objects to other pages.

So why don't you create a small class that includes all your parameters and pass an instance of that? Learn more. Asked 4 years, 2 months ago. Active 2 months ago. Viewed 17k times.

If it isn't, then use SessionState. Not sure how to fix that. That means, the the parameters you pass can't be converted to a string in the background.

Can you show us the parameters you pass? I cut and pasted this exact class RestaurantParams into my project to test and I get the same error. I'm thinking maybe UWP has changed this somehow.Help your users be more productive by letting them view independent parts of your app in separate windows. When you create multiple windows for an app, the taskbar shows each window separately. Users can move, resize, show, and hide app windows independently and can switch between app windows as if they were separate apps.

Important APIs : Windows. ViewManagement namespaceWindows. WindowManagement namespace. While each app layout is unique, we recommend including a "new window" button in a predictable location, such as the top right corner of the content that can be opened in a new window.

Also consider including a context menu option to "Open in a new window". To create separate instances of your app rather than separate windows for the same instancesee Create a multi-instance UWP app.

An app view is the pairing of a thread and a window that the app uses to display content.

Show multiple views for an app

Having to work on different UI threads can complicate multi-window apps. The main view for your app is always hosted in an ApplicationView. Content in a secondary window can be hosted in a ApplicationView or in an AppWindow. If your app targets earlier versions of Windows 10, you must use ApplicationView to create secondary windows. AppWindow is currently in preview. This means you can submit apps that use AppWindow to the Store, but some platform and framework components are known to not work with AppWindow see Limitations.

You can use APIs on these classes to get information such as the window bounds. To retrieve an instance of these classes, you use the static CoreWindow. GetForCurrentView method, or Window. Current property. In addition, there are many classes that use the GetForCurrentView pattern to retrieve an instance of the class, such as DisplayInformation.

This abstraction layer lets you write the same code regardless of which windowing host the XAML runs in. This table shows code that does not work correctly across windowing hosts, and the new portable code that you can replace it with, as well as some APIs that you don't need to change.

There is a document about printing here: Print from your app. And here is the printing Sample. Both the sample and the document shows how to print one page. So you will need to change the sample code a little bit to print more than one page. In scenario 1, the basic print function, when you want to print a page, you will need to call the PreparePrintContent method in the codebehind to initialize print content.

Then when you try to show the print preview, it will trigger PrintDocument. Paginate Eventin that event handler you can prepare the content that needs to be printed. And you will need to do most of the changes in this event handler.

You could try this on your side. When you click the print button in scenario1, it should show you two pages. Attachments: Up to 20 attachments including images can be used with a maximum of 3.

Your app can have multiple pages: when a user launches a UWP app, the application code creates a Frame to place inside of the application's Window.

The Frame can then navigate between the application's Page instances. Most pages follow a common layout structure, and this article covers which UI elements you'll need, and where they should go on a page.

Your app layout begins with the navigation model you choose, which defines how your users navigate between pages in your app. For this article, we'll discuss two common navigation patterns: left nav and top nav. For guidance on choosing other navigation options, see Navigation design basics for UWP apps. Left nav, or the nav pane pattern, is generally reserved for app-level navigation and exists at the highest level within the app, meaning that it should always be visible and available.

We recommend left nav when there are more than five navigational items, or more than five pages in your app. The nav pane pattern typically contains:. The menu button allows users to expand and collapse the nav pane.

When the screen size is larger than px, clicking the menu button collapses the nav pane into a bar. Top nav can also act as top-level navigation. While left nav is collapsible, top nav is always visible. Next, you might want to provide users with easy access to your app's most common tasks. A command bar can provide access to app-level or page-level commands, and it can be used with any navigation pattern. Finally, content varies widely from app to app, so you can present content in many different ways.

Here, we describe some common page patterns that you might want to use in your app. Many apps use some, or all, of these common page patterns to display different types of content.

Likewise, feel free to mix and match these patterns to optimize for your app. Landing pages, also known as hero screens, often appear at the top level of an app experience.

The large surface area serves as a stage for apps to highlight content that users may want to browse and consume. Collections allow users to browse groups of content or data. Grid view is a good option for photos or media-centric content, and list view is a good option for text-heavy content or data. Both panes are fixed and have vertical scrolling.

When an item in the list view is selected, the content view is correspondingly updated. A form is a group of controls that collect and submit data from users. Most, if not all apps, use a form of some sort for settings pages, log in portals, feedback hubs, account creation, or other purposes. To see how these patterns can be implemented, check out our UWP sample apps :. You may also leave feedback directly on GitHub. Skip to main content. Exit focus mode. Navigation Your app layout begins with the navigation model you choose, which defines how your users navigate between pages in your app.

Left nav Left nav, or the nav pane pattern, is generally reserved for app-level navigation and exists at the highest level within the app, meaning that it should always be visible and available. The nav pane pattern typically contains: Navigation items Entry point into app settings Entry point into account settings The NavigationView control implements the left nav pattern for UWP.

When a navigation item is selected, the Frame should navigate to the selected item's Page.
