LazyView isn’t out in stable yet at the time of writing this blog but will be part of version 1.1 and available in the nightly pre-release versions. With LazyView you can make any view lazy loading, including the ones used in TabView. That is a question we hear a lot, and with good reason! Lazy loading is not built into the TabView directly, however, also in the Xamarin Community Toolkit, we have the LazyView. I’ll admit that the tabs shown in this post might need a bit more styling… What About Lazy Loading? Another thing that stands out is that you can use a ControlTemplate to style the TabViewItem any way you want. But by not assigning any content and instead assigning an event to the TabTapped property, you suddenly gain a button instead of another tab. The thing you might notice about this code is that the middle action button is just another TabViewItem. The code has been adapted to show just the crucial things here. ![]() This is again taken from an example in the Xamarin Community Toolkit sample app. To achieve this, we can use the following code. You can see an example in the screenshot below. I’ve already mentioned it: the floating action button that looks so fancy in all those designs. See this full sample code in context (or run it!) in the Xamarin Community Toolkit sample app. When running the above code, it will show up like in the screenshot below. So, in practice, the TabViewItems will act as your actual tabs. But more importantly inside of these items you will specify the content. Those items even have more properties to customize. If we look a little bit closer, we see that we have a TabView at the root and inside of the you’ll need to use TabViewItem. Placement top or bottom, background color, specify a height, enable an indicator and give it a color. You can already see so many options that are not available on the default tab bar. Basic Usageīasic usage of the TabView looks like below. The TabView is available in the Xamarin Community Toolkit, today! But before you go off and install it right away, let me show you a couple of the cool things it can do. We’re able to bind items to tabs, scroll through them (both the pages as the actual tabs!), have animations, badges, and most of all… We can implement that big, floating, rounded action button. To be able to provide you with all the above, and more, there is now… TabView! TabView: All You’ve Ever Wanted from a Tab Barīy creating a tab bar from all Xamarin.Forms elements a whole new world opens. There was a big ask for having a bit action button floating on that tab bar or being able to scroll through tabs, have animations, and more! Over the years we’ve surfaced more APIs that allow you to style the tab bar more, but the native platforms kept limiting us. This works great and maps to the native equivalents on all platforms supported, but that is just the thing: it uses the native look and feel. The way to implement a tab bar in Xamarin.Forms is by using a TabbedPage. In this blogpost we’ll learn what it’s all about. With the TabView you have full control over the look-and-feel of the tab bar. To overcome this, we’ve added the TabView to the Xamarin Community Toolkit. One of the hardest parts of apps to customize is the tab bar.
