Thank you for writing.
Currently, we do not have RadEditor for WinForms
control. We have plans to make one in the future, but we cannot give you a specific timeframe when it will be available.
Fortunately, we have a ASP.NET RadEditor
you can use in your windows application. You can learn more about how to do that in the Knowledge Base under: Using Telerik RadEditor for ASP.NET in a Windows application.
This RadEditor has all the buttons you may need to format your text, so you do not need to implement all that functionality yourself.
Should you have additional questions, do not hesitate to contact us.
All the best,
the Telerik team
