UI for ASP.NET Core
Declarative initialization—a feature that serializes the component declaration as an MVVM declarative configuration instead of an inline initialization script—is supported in Telerik UI for ASP.NET ColorPicker. It is beneficial in cases when the Content Security Policy (CSP) is enabled as it eliminates the requirement to call the methods that defer the initialization script generated after the component's HTML markup.
