  Hi,
  
  Migrate from 2010v1 to 2025v2 399 in ASP.NET WebForms NET Framework 4.8.1.

  Using C1FormDecorator ?

  My legacy code:

  <%@ Register Assembly="C1.Web.UI.Controls.3" Namespace="C1.Web.UI.Controls.C1FormDecorator" TagPrefix="cc3" %>

  any alternative control ?

  Hello Enrique,

  There is no direct 1:1 replacement for ‘C1FormDecorator’ in the modern assemblies. Instead, you would typically:

  1. Remove ‘C1FormDecorator’.
  2. Identify the controls that were being decorated.
  3. Apply the corresponding Wijmo extender, such as ‘WijButton’, ‘WijTextbox’, ‘WijCheckbox’, etc., to the target controls as needed.

  For more information, please refer to the following documentation:
  
  https://developer.mescius.com/componentone/docs/webforms/online-wijmoopenjuiceui/FormDecorators.html

  That said, our recommendation is to remove ‘C1FormDecorator’ from the application and use standard CSS styling instead, as it provides a more modern and maintainable approach.

  Regards,
