Plugin Segmented Control for Xamarin Forms and .NET Standard

NuGet Badge

Please star this project if you find it useful. Thank you!

Why this library?

There are other Segmented Control libraries out there. This library adds two important capabilities:

  • It works across all four key platforms: iOS, Android and UWP - all other libraries I've encounted lack UWP and/or MacOS.
  • It's based on .NET Standard 2.0

Furthermore, this library is has more flexibility and features than other libraries that I'm aware of.

Enjoy! And please don't forget to star this project if you find it useful and/or provide feedback if you run into issues or shortcomings.

How to used

Using this plugin is easy.

iOS

Add initializer to AppDelegate

public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
    global::Xamarin.Forms.Forms.Init();

    SegmentedControlRenderer.Initialize();
    ...
}

UWP

You need to add the assembly to App.xaml.cs in you project. For more details see the Xamarin documentation here.

var assembliesToInclude = new List<Assembly> {typeof(SegmentedControlRenderer).GetTypeInfo().Assembly};

Xamarin.Forms.Forms.Init(e, assembliesToInclude);

Android

No special needs.

For using custom fonts with Android see this blog post: https://blog.verslu.is/xamarin/xamarin-forms-xamarin/custom-fonts-with-xamarin-forms-revisited/

.NET Standard

The Xamarin Forms must use .NET Standard. I suggest using .NET Standard 2.0+.

            </control:SegmentedControl>
        </StackLayout>
    </ContentPage.Content>
</ContentPage>

You can bind to the SegmentSelectedCommand for notification in your view model when a segment change has occurred.

<control:SegmentedControl
    SegmentSelectedCommand="{Binding SegmentChangedCommand}"
</control:SegmentedControl>
