Let wrap it into a TabView by a ForEach, and don’t forget to set tag for it content(index). Because we don’t know what view we will put into in the future, that why we need to make this view Generic with Ĭontent for each tab we will get from the closure let content: (Int) -> Content, with Int is the index of that tab.
The input of CustomTabView is tab item array, selectedIndex, and content view for each tab. TabView.TabItemTemplateSelector Property (Microsoft.UI.Xaml. The control is fully customisable and comes with rich functionality, including item selection, tabs and header customisation, templates and a flexible styling API. For more information, you guys can read it here. Gets or sets a selection object that changes the DataTemplate to apply for content, based on processing information about the content item or its container at run time. Each TabView item has an associated content displayed on selection. Therefore, we will use the attribute name ViewBuilder. When I open the application, all the pages in TabView enter the initialization method, but if I go to another page and come back, it does not enter the initialization method or the constructor and does not take its data. We are using the Int value type to keep track of the currently selected tab. I tried to use refresh view but the page does not appear at all, the respective page in TabView is white and the content is missing. Then we are using the tag modifier for each of the tab items.
Tabview selection code#
Démo: Voici un code simplifié décrivant lapproche (avec lutilisation de vos vues). Firstly we are using the VStack views with a Button inside to select the next tab or the last the first accordingly. TabViewItem can be selected by setting its IsSelected(bool) property to True. Lidée est de joindre dynamiquement la TabViewsélection au NavigationViewcontenu. However, if this is done after scrolling through my TabView's contents what happens is the selection changes many times as the size changes, causing the TabView to erratically scroll through many pages, rather than stay on the same selection. We aim to reuse this component in other projects, we will create a view that can adapt with any View. NET MAUI exposes properties that help you work with the item selection: SelectedItem(of type ) set the selected item. When a tab is tapped the second view in the HStack disappears and the TabView resizes to fill the space. And the final thing we will build in this tutorial is CustomTabView.
