A given rectangle might, for example, have an X-coordinate that is in device units, a Y-coordinate that is in proportional units, a height that is in proportional units, and a width that is in device units, or any other combination of device and proportional units.

Application developers should remember the following points when specifying a structure that will define the layout bounds of a child element: + For elements whose height and width fit on the screen, proportional position dimensions in the range [0,1] represent elements that are completely on the screen, regardless of whether the height, width, or both are specified in device or proportional units.The above point means that, to specify an element in the lower right hand corner of the screen and that is half as wide and half as all as the screen, with a value of All, the application developer would specify "0.1, 0.1, 0.5, 0.5".The app developer can inadvertently cause child elements for which one or both size dimensions were specified proportionally to be displayed partially off the screen, or hidden altogether, by specifying device-unit positions that do not leave enough room for the calculated size of the child.Each part of the bounding structure is interpreted according to the value that controls it. A given rectangle might, for example, have an X-coordinate that is in device units, a Y-coordinate that is in proportional units, a height that is in proportional units, and a width that is in device units, or any other combination of device and proportional units. Rectangles that, when interpreted by using the current set on the child, represent bounding boxes that are partially or wholly off-screen—for example, by having a width that is larger than the screen width—may give unexpected results. + + + + Interpret all dimensions proportionally. + + + Interpret height property as proportional to layout height. + + + Disable all flags. + + + Equivalent to both XProportional | YProportional. + + + Equivalent to both WidthProportional | HeightProportional. + + + Interpret width property as proportional to layout width. + + + Interpret x property as proportional to the remaining space after width is accounted for. + + + Interpret y property as proportional to the remaining space after height is accounted for. + + + A visual control used to indicate that something is ongoing. + + This control gives a visual clue to the user that something is happening, without information about its progress. + + + + XAML for Xamarin.Forms supports the following properties for the class: + + + Property + Value + + + Color + + A color specification, with or without the prefix, "Color".

All of the visual elements in the namespace inherit from class, so they can all be used to bind the data behind their user interface elements to View Models that are supplied by the application developer. + + To bind the data behind a property in a , typically a view, to a property in the View Model, application developers should do the following. + First, the developer creates a pair of properties on the view, one of which is a , and the other of which is a property of whatever type is required. In the code below, MockBindableObject stands in for what would typically be a user interface object in production code. Application developers should note the use of and to get and set the value on the bound property; The property of the desired type provides the interface that the target of the bound property will implement. + ( + // o => o.Foo, default (string) + // ); + + public string BoundName + { + get { return (string) GetValue (BoundNameProperty); } + set { SetValue (BoundNameProperty, value); } + } +} + ]]> + Second, the developer creates the implementation for the bound property in a class that implements the interface. In the MVVM design pattern, this is typically done by the View Model. Application developers should implement the interface on classes that they want to use as View Models. In the example below, app developers should take note of the idiomatic way that the Name property is implemented to, first, ensure that the property actually changed and return if it did not, and only then assign the value and call the method. Additionally, the Name property in the example below merely wraps the name field. In practice, the application developer may choose a different model in which to store application data. + + Third, and finally, the application developer binds an instance of a BindableObject to an instance that implements INotifyPropertyChanged. In the vocabulary of the MVVM design pattern, this is "binding an instance of the View to an instance of a View Model." Once this step is complete, changes in the data are propagated between the View and View Model in a way that is determined by the value of the enumeration, if any, that was passed during the binding step. + The code below, when included in a project that reference the classes above, creates an instance of both MockBindable and MockViewModel, performs some intitialization, sets the binding, and then demonstrates a one-way binding.

If the developer provides a 4-digit hexadecimal number, then the data are interpreted as above, except that the first digit specifies the alpha channel. For example, "#1234" specifies the color that is represented by "#11223344". Finally, if the developer provides a 6 digit hexadecimal number, the data are interpreted as a fully opaque color with those RGB values. For example, "#112233" specifies the color that is represented by "#FF112233". + When specifying a color with a string, app developers can use color name in isolation, or prefix it with "Color.".

Currently, the default behavior is to retain item data in their generated cells when they are not needed. (Items are not needed, for example, when they are far enough off screen that their display is not imminent.) This behavior corresponds to a value of . For performance reasons, it is likely that the default behavior will be changed to in a future release. In the meantime, for memory and performance reasons, app developers should specify when constructing a new List View. + The performance advantage of is so great that application developers have been provided with a XAML syntax shortcut for initializing List Views. Instead of x:TypeArguments syntax that specifies a parameter for the constructor, XAML for Xamarin.Forms provides a XAML attribute for a non-existent property that corresponds to the caching strategy argument of the constructor. Application developers can set the CachingStrategy attribute to either of the RecycleElement (preferred) or RetainElement values to choose a caching strategy. For example: + + + + + + + + +]]> + + When devolopers specify , OnElementChanged events are not raised when cells are recycled. Instead, the cell is retained and its property values change when the binding context is updated to that of an available cell, OnElementPropertyChanged events are raised.

Note that the NamedColorPage class, defined in as a sublcass of in another file in the sample application, simply displays RGB data, a with its background color set to the color that the user selected, and, finally, hue, saturation, and luminosity data. + The sample below illustrates three key concepts. First, the "Master" portion of the MasterDetailPage is represented by the property, which is set to a element in this example. This element contains a label and a list of colors. Second, the "Detail" portion of the is represented by the property, which, in this example, is set to the NamedColorPage that was noted above. Third, and finally, the page that is represented by the property is displayed by setting the property to ; That is, the property controls whether or not the page that is represented by the is presented to the user. + The page must have its property set.

Objects that are derived from the see class are most prominently used as the top level UI element in Xamarin.Forms applications. Typically, application developers will provide such an object to the target platforms by returning it from a static method that the developer created in a project that references . The contents of a typical App.cs file that would appear in a project that reference are shown below: + + + + While a object was returned in the example above, note that any class that extends could have been passed, instead. For example, by using conditional compilation or by checking the platform, the developr can pass a to Windows Phone applications, in order to better match the style of the user interface on that platform, while passing objects or other Page types to the other platforms. + The other projects in the solution that target the Windows Phone, iOS, and Android platforms can call the GetMainPage method to obtain the descendant that describes the portable user interface. This object can then be used with platform-specific static methods or extension methods to incorporate it into the native UI for each platform. + In each platform-specific project, Application developers must call the Xamarin.Forms.Forms.Init() method, with platform-specific parameters, before they get or create any elements. + Each targeted platform uses the returned page in a different way. The Xamarin.Forms.Platform.iOS library provides Xamarin.Forms.Page.CreateViewController() extension method, which returns a UIViewController that application developers can assign to the UIWindow.RootViewController property of the top-level UI. This code is typically placed inside the UIApplicationDelegate.FinishedLaunching override for the main application class. A typical example is shown below: + + +using System; +using Xamarin.Forms; + +namespace MyFirstFormsApp.iOS +{ + [Register("AppDelegate")] + public partial class AppDelegate : UIApplicationDelegate + { + UIWindow window; + + public override bool FinishedLaunching(UIApplication app, + NSDictionary options) + { + Forms.Init(); + + window = new UIWindow(UIScreen.MainScreen.Bounds); + + window.RootViewController = App.GetMainPage().CreateViewController(); + window.MakeKeyAndVisible(); + + return true; + } + } +} + + + + The Xamarin.Forms.Platform.Android.AndroidActivity class provides the Xamarin.Forms.Platform.Android.AndroidActivity.SetPage method, which performs the work that is necessary to make its page argument the top-level UI element of the Xamarin.Forms.Platform.Android.AndroidActivity. A typical example is shown below: + + +using System; +using Android.App; +using Android.OS; +using Xamarin.Forms.Platform.Android; + + +namespace MyFirstFormsApp.Android +{ + [Activity(Label = "MyFirstFormsApp", MainLauncher = true)] + public class MainActivity : AndroidActivity + { + protected override void OnCreate(Bundle bundle) + { + base.OnCreate(bundle); + + Xamarin.Forms.Forms.Init(this, bundle); + + SetPage(App.GetMainPage()); + } + } +} + + + For Windows Phone, provides an extension method for that is called . This method returns a System.Windows.UIElement object that has the page that was passed to it as its current page. A typical example is shown below: + + +using System; +using System.Windows; +using System.Windows.Controls; +using System.Windows.Navigation; +using Microsoft.Phone.Controls; +using Microsoft.Phone.Shell; + +using Xamarin.Forms; + + +namespace MyFirstFormsApp.WinPhone +{ + public partial class MainPage : PhoneApplicationPage + { + public MainPage() + { + InitializeComponent(); + + Forms.Init(); + Content = Phoneword.App.GetMainPage().ConvertPageToUIElement(this); + } + } +} + + In addition to their role as the main pages of applications, objects and their descendants can be used with navigation classes, such as or , among others, to provide rich user experiences that conform to the expected behaviors on each platform. + XAML for Xamarin.Forms supports the following properties for the class: + + + Property + Value + + + BackgroundImage + + A local file specification that identifies an image. + + + + Icon + + A local file specification that identifies an image. + + + + Padding + + A comma-separated list of 4 integers that represent a structure. + + + + Title + + Text that represents the title of the page. + + + + ToolbarItems + + A list of ToolBarItem elements. + + + + + + + Creates a new element with default values. + To be added. + + + This method is for internal use. + To be added. + + + This method is for internal use . + To be added. + + + Indicates that the is about to appear. + To be added. + + + Identifies the image used as a background for the . + To be added. + To be added. + + + Identifies the property. + To be added. + + + This method is for internal use. + To be added. + + + Indicates that the is about to cease displaying. + To be added. + + + Title of the displayed action sheet.
