We will want to use a layout to define the structure of our user-interface and we will want to bind data to views inside that layout to present the news feed content. 4 | 5 | ## Layouts 6 | 7 | ![Layouts Available in .NET MAUI](img/layouts.png) 8 | 9 | Layouts diagram courtesy of [Microsoft docs](https://learn.microsoft.com/dotnet/maui/user-interface/layouts/?view=net-maui-7.0) 10 | 11 | .NET Multi-platform App UI (.NET MAUI) layout classes allow you to arrange and group UI controls in your application. Choosing a layout class requires knowledge of how the layout positions its child elements, and how the layout sizes its child elements. In addition, it may be necessary to nest layouts to create your desired layout. 12 | 13 | For our application, we will prefer a StackLayout because not all RSS feeds are created with images and supporting content where a Grid or FlexLayout would help create a more interesting layout. 14 | 15 | ![The desired layout of our feeds page](img/results.png) 16 | 17 | We'll start with a simple CollectionView that will use a StackLayout to present a list of feeds stacked vertically. 18 | 19 | ### Model 20 | 21 | We will be downloading details about the newsfeed and will need a class to represent it. 22 | 23 | RSS content will need to be downloaded from each feed and presented in the project. It's preferred to have an object model representing the RSS feed and we can create one from a feed avaialble on the web, like my blog at `https://jeffreyfritz.com/feed` 24 | 25 | We can easily convert the xml content with the **Paste Special** feature in Visual Studio. Copy the content of the XML file to your clipboard with Ctrl+C and select Edit - Paste Special - Paste XML as Classes. I have updated and made this content available for you as the RSS class in the project. 26 | 27 | --- 28 | > **NOTE** 29 | 30 | > After completing the demo, I realized there is a SyndicationFeed object and package available for .NET. I will update the content of the workshop to use this standard object instead of the serialization I wrote 31 | 32 | --- 33 | 34 | Let's also define the NewsFeed object we will work with in the project 35 | 36 | 1. Open `Models/NewsFeed.cs` 37 | 2. In `NewsFeed.cs`, copy/paste the properties: 38 | 39 | ```csharp 40 | public record NewsFeed(string SourceUrl, string Title) { 41 | 42 | public NewsFeed() : this(string.Empty, string.Empty) { } 43 | 44 | } 45 | ``` 46 | 47 | ### Displaying Data 48 | 49 | We can display hard coded data of any data type in a `CollectionView` in our `MainPage.xaml`. This will allow us to build out our user interface by setting the `ItemTemplate` with some simple images and labels. 50 | 51 | We first need to add a new namespace at the top of the `MainPage.xaml`: 52 | 53 | ```xml 54 | xmlns:model="clr-namespace:MyNewsReader.Models" 55 | ``` 56 | 57 | This will allow us to reference the Monkey class above for data binding purposes. 58 | 59 | Add the following into the MainPage.xaml's `ContentPage`: 60 | 61 | ```xml 62 | 64 | 65 | 66 | 67 | 68 | 69 | 70 | 71 | 72 | 73 | 81 | 82 | 83 | 84 | ``` 85 | 86 | 87 | 88 | If we wanted to display the two strings vertically on top of each other, we could wrap two `Label` controls inside of a `VerticalStackLayout` and assign font sizes to stand out: 89 | 90 | 91 | ```xml 92 | 93 | 96 | ``` 97 | 98 | 99 | 100 | ### Run the App 101 | 102 | Ensure that you have your machine setup to deploy and debug to the different platforms: 103 | 104 | * [Android Emulator Setup](https://docs.microsoft.com/dotnet/maui/android/emulator/device-manager) 105 | * [Windows setup for development](https://docs.microsoft.com/dotnet/maui/windows/setup) 106 | 107 | 1. In Visual Studio, set the Android or Windows app as the startup project by selecting the drop down in the debug menu and changing the `Framework` 108 | 109 | 110 | ![Visual Studio debug dropdown showing multiple frameworks](img/framework-selection.PNG) 111 | 112 | 2. In Visual Studio, click the "Debug" button or Tools -> Start Debugging 113 | - If you are having any trouble, see the Setup guides for your runtime platform 114 | -------------------------------------------------------------------------------- /doc/1-BindingData/img/layouts.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/csharpfritz/MauiWorkshop/155283ecb14e12968cb677252514aead83b863b7/doc/1-BindingData/img/layouts.png -------------------------------------------------------------------------------- /doc/1-BindingData/img/results.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/csharpfritz/MauiWorkshop/155283ecb14e12968cb677252514aead83b863b7/doc/1-BindingData/img/results.png -------------------------------------------------------------------------------- /doc/1-BindingData/src/MyNewsReader.sln: -------------------------------------------------------------------------------- 1 |  2 | Microsoft Visual Studio Solution File, Format Version 12.00 3 | # Visual Studio Version 17 4 | VisualStudioVersion = 17.0.31903.59 5 | MinimumVisualStudioVersion = 10.0.40219.1 6 | Project("{9A19103F-16F7-4668-BE54-9A1E7A4F7556}") = "MyNewsReader", "MyNewsReader\MyNewsReader.csproj", "{13F698DD-A76C-4AF9-9BAA-842F64F03CEC}" 7 | EndProject 8 | Global 9 | GlobalSection(SolutionConfigurationPlatforms) = preSolution 10 | Debug|Any CPU = Debug|Any CPU 11 | Release|Any CPU = Release|Any CPU 12 | EndGlobalSection 13 | GlobalSection(ProjectConfigurationPlatforms) = postSolution 14 | {13F698DD-A76C-4AF9-9BAA-842F64F03CEC}.Debug|Any CPU.ActiveCfg = Debug|Any CPU 15 | {13F698DD-A76C-4AF9-9BAA-842F64F03CEC}.Debug|Any CPU.Build.0 = Debug|Any CPU 16 | {13F698DD-A76C-4AF9-9BAA-842F64F03CEC}.Debug|Any CPU.Deploy.0 = Debug|Any CPU 17 | {13F698DD-A76C-4AF9-9BAA-842F64F03CEC}.Release|Any CPU.ActiveCfg = Release|Any CPU 18 | {13F698DD-A76C-4AF9-9BAA-842F64F03CEC}.Release|Any CPU.Build.0 = Release|Any CPU 19 | EndGlobalSection 20 | GlobalSection(SolutionProperties) = preSolution 21 | HideSolutionNode = FALSE 22 | EndGlobalSection 23 | EndGlobal 24 | -------------------------------------------------------------------------------- /doc/1-BindingData/src/MyNewsReader/App.xaml: -------------------------------------------------------------------------------- 1 |  2 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | -------------------------------------------------------------------------------- /doc/1-BindingData/src/MyNewsReader/App.xaml.cs: -------------------------------------------------------------------------------- 1 | namespace MyNewsReader; 2 | 3 | public partial class App : Application { 4 | public App() { 5 | InitializeComponent(); 6 | 7 | } 8 | 9 | protected override Window CreateWindow(IActivationState activationState) { 10 | 11 | if (DeviceInfo.Current.Idiom == DeviceIdiom.Desktop) { 12 | 13 | return new Window(new AppShell()) { 14 | Width = 600 15 | }; 16 | 17 | } 18 | 19 | return new Window(new AppShell()); 20 | 21 | } 22 | } 23 | -------------------------------------------------------------------------------- /doc/1-BindingData/src/MyNewsReader/AppShell.xaml: -------------------------------------------------------------------------------- 1 | 2 | 8 | 9 | 10 | 11 | 16 | 26 |
