Checkbox For Xamarin.Forms

Xamarin.Forms is great. But, every now and then, it falls short on some basic modern controls e.g checkbox, radio buttons, cards, etc. Luckily, Xamarin community is large and very engaged with the platform. You can find plethora of custom controls or blogs on how to build custom controls for your project needs.

In recent years, I have created a bunch of custom controls that I am sure the community at large can benefit from. One such controls is a simple Checkbox. There are lots of implementations of checkbox available, but I wanted something simple and light, so I created one. Here’s how the checkbox works…

Pro Tip: Useful Code Snippets For Your Xamarin.Forms Development

Code snippets are a hidden gem in Visual Studio that most of us do not pay much attention to. Utilizing them correctly can increase productivity when we have a lot to code. In Visual Studio, code snippets are available for multiple programming languages e.g. C#, F#, XML, HTML, CSS, Python, etc. They are extremely useful when we have a bunch of boiler plate code for our properties, constructors, bindable properties, etc.

Code snippets can be a huge topic, but in this post, I will list some of the XAML and C# code snippets useful when developing Xamarin.Forms mobile applications.

In this post,

Tutorial: BottomNavigationView and ViewPager in Xamarin.Android

Android introduced BottomNavigationView in API 25.1 and I like it. To be honest, one of the biggest difference between iOS and Android for me was the placement of tabs. I enjoyed ActionBar tabs when they were a thing and loved the fact that I could swipe the tabs as I wished. But, when I used the bottom tabs in Android recently, I fell in love instantly. In today’s world of giant smartphones, one can only reach the bottom of the device during one-handed operations, so I loved the fact that I could use my hardware back button to navigate back and switch between tabs all with a single thumb.

Prism.Forms EventAggregator

Using Prism.Forms EventAggregator with Xamarin.Forms

If you are building a Xamarin.Forms app, it should be a no-brainer that you use MVVM pattern for your code base. It should also be a no-brainer that you give Prism.Forms a try.
