Adding custom font/selecting text color to the Tab item title.In this article I’m going to show you how to customize your TabbedPage by doing some cool stuff, that covers the following topics: Using a command, you bind to an ICommand, similar to many other controls.When working with the TabbedPage in most cases we have a design requirement that require us to do some customizations. Using an event, you simply use the Activated event. If you want to perform an action when a toolbar item is clicked, you have the option of an event, or a command. Note: Toolbar Items are not, by default, updatable, after they have been added to the toolbar, however there are ways around this. Depending upon where you want to place it, use the Order property and set to Primary or Secondary. The secondary toolbar, as you can see in the screenshots above, is either a drop down menu, with more menu options, or a secondary bar, underneath the primary. You do this with the Priority Property, not the Ordering property. Ordering the icons, or text, is simply done by adding an integer from 0 to X, in order of left to right. In iOS, the same again, as it expands horizontally, taking the top priority. In Android, it expands horizontally, even taking priority on the title. In UWP, it expands vertically, in both the desktop and phone version. If you type in a really long piece of text, interestingly, this toolbar is quite high on the priority of what gets displayed. Add text to the Text property and it will be displayed. Note that I used the full color png for the icon image and it was automatically converted via the platform. In Android, the icon is shown in full color. You can not have a color icon, in UWP or iOS. In iOS they will be turned to the default theme color, and not shrunk. An interesting thing to note, is that icons will always be turned white or black in UWP, depending upon the theme of the app, and shrunk to size. UWP expects an icon and will leave a space there if none is specified. There are a number of options that allow you to change certain visual aspects and location of each ToolbarItem. If your ContentPage isn’t inside a NavigationPage, or you disabled your NavigationBar, then the ToolbarItems will not be displayed. ![]() The ContentPage must be part of a NavigationPage and the NavigationBar must not have been disabled. Here is an example of how to add ToolbarItems in Xamarin Forms, to a ContentPage. In UWP, the toolbar items are added to the Command Bar (App Bar prior to UWP). In iOS, the toolbar items are added to the NavigationBar. In Android, the toolbar items are added to the App Bar (a.k.a Action Bar). Toolbar Itemsįirst, lets have a look at how Toolbar Items look on each platform. In this post, I will go through how to add and customize items in the toolbar, however I normally recommend to steer clear of this functionality, and create your own navigation bar from scratch, due to the limitations on customization. The difficult part with this abstraction, is the need for it to be separate or included in the navigation bar. ToolbarItems are the individual items you add to the NavigationBar. The Xamarin Forms Toolbar is an abstraction of the extensions you can add to the NavigationBar on each platform.
