Navigation can be performed within a tab, provided that the ContentPage object is wrapped in a NavigationPage object. For more information, see Combined View Controller Interfaces in the iOS Developer Library. This is because, on iOS, a UITabBarController always acts as a wrapper for the UINavigationController. While a NavigationPage can be placed in a TabbedPage, it's not recommended to place a TabbedPage into a NavigationPage. This is accomplished in XAML as follows: This is achieved by adding the Page objects to the TabbedPage.Children collection. Populate a TabbedPage with a Page collectionĪ TabbedPage can be populated with a collection of child Page objects, such as a collection of ContentPage objects.
For more information, see Xamarin.Forms Shell.
However, Xamarin.Forms Shell enables pages accessed through a tab bar to be created on demand, in response to navigation. This can lead to a poor user experience, particularly if the TabbedPage is the root page of the application. In a TabbedPage, each Page object is created when the TabbedPage is constructed. With both approaches, the TabbedPage will display each page as the user selects each tab. For more information, see Populate a TabbedPage with a template. Assign a collection to the ItemsSource property and assign a DataTemplate to the ItemTemplate property to return pages for objects in the collection.For more information, see Populate a TabbedPage with a Page Collection. Populate the TabbedPage with a collection of child Page objects, such as a collection of ContentPage objects.Two approaches can be used to create a TabbedPage: For more information about converting SVG files to vector drawable resources, see Add multi-density vector graphics on .įor more information, see Xamarin.Forms TabbedPage with SVG tab icons. Alternatively, SVG files can be converted to vector drawable resources, which can automatically be displayed by Xamarin.Forms.

If there are more than five tabs, and the tab list is at the bottom of the screen, a More tab will appear that can be used to access the additional tabs.
