Change Theme Swatch at Runtime in C# Code

[Pedro]

I configured the application to use customized Theme Colors (Swatches) following the link:

https://docs.telerik.com/devtools/maui/styling-and-themes/customize-the-theme#customizing-the-theme-colors-swatches

Next as requirement I should change the Theme Color (Swatch) at run-time based on the device, using C# code, the only link I found was:

https://docs.telerik.com/devtools/maui/knowledge-base/change-telerik-theme-runtime

But here the Telerik Theme is changed at run-time using only pre-defined Telerik Themes. So my question is: how can I change Default Theme Colors (Swatches) at run-time using C# code?

Thanks

Hi Pedro,

To achieve the desired functionality in C#, you need to set TelerikThemeResources.AppTheme to the desired theme. After that, merge the custom swatch ResourceDictionary to apply the custom colors to the selected theme.

I’ve created a sample project that demonstrates how to switch from the TelerikPurple theme to the TelerikTurquoise theme, and then merge a custom swatch defined in CustomTelerikSwatch.xaml.

I hope this project will be of help. If you need further assistance, please reach out.
