Theming Official

The advanced Theming functionality in Telerik UI for .NET MAUI has now moved from Preview to Official Release, enabling developers to build more visually cohesive and brand-consistent applications than ever before. The Official Theming mechanism empowers you with built-in Light and Dark modes, advanced customization options, and extended support across key controls. Whether you're creating enterprise dashboards or consumer-grade mobile apps, the Theming system helps you accelerate UI development while ensuring a polished, responsive, and modern user experience across all platforms.  

It also comes with two predefined themes: 

- Platform Theme, which applies a native look and feel per platform—iOS apps will appear with iOS styling, Android apps with Android styling, and so on. 

- Telerik Theme, which delivers a consistent appearance across all platforms, allowing you to apply different color swatches to match your brand identity and design language. 

Popular components such as DataGrid, CollectionView, Calendar, Scheduler, and ComboBox now fully support the theming system – bringing high-impact design consistency to your development toolkit.
