This weekend I was looking to update my settings page on my latest app, My Cadence, and introduce a new option to allow the user to select a default theme for their application. In previous applications I have built, I have used the Picker control to give users the option to pick a setting: There are a few ways to implement this features. This is a pretty good experience, however I wanted to see if there was something new in Xamarin.Forms 5 that I could leverage to create a better experience. Browsing the documentation I stumbled upon the brand new RadioButton control that is fully templatable! This means you can completely customize the look and feel of the control while still maintaining the functionality of the control. Whether using WPF, ASP.NET, WinForms, HTML5 or Windows 10, DevExpress tools help you build and deliver your best in the shortest time possible. So, let’s take a look at how to leverage this new feature to create a new way for my users to select the theme. DevExpress engineers feature-complete Presentation Controls, IDE Productivity Tools, Business Application Frameworks, and Reporting Systems for Visual Studio, Delphi, HTML5 or iOS & Android development. The first thing to do is to add the RadioButton to your application. To create a theme selection UI we will create a Grid with 3 columns each with a RadioButton in it. This will result with the default control that displays the RadioButton besides text. One of the beautiful parts of the new RadioButton is that it has control templating built in.
