Rounded RadForm in Winform

[Sungkyun]

Hello, I want to create a rounded form.

I want to convert existing forms created using RadForm into rounded forms.

I want to create a BaseRoundedForm that inherits from RadForm.

Is there a way to do this?

I'm using C#.

Since ShapedForm inherits from Form, it may be difficult to apply it to existing RadForm forms.

Hello, Sungkyun,

As of R3 2021 RadForm comes with rounded corners by default. Windows OS 11 brings plenty of great features, where the rounded corners are just a piece of the improved design. This is why we also provide a more elegant experience to RaForm in desktop applications, giving smooth, rounded edges.

The rounded corners are enabled by default when the operating system is Windows 11. This functionality can be controlled by the Telerik.WinControls.WindowsSettings.EnableRoundedCornersDefaultValue property. More information is available here: Rounded Corners - Telerik Presentation Framework - Telerik UI for WinForms

Below you can see a very simple RadForm with rounded corners:

So, while you keep Telerik.WinControls.WindowsSettings.EnableRoundedCornersDefaultValue=true, you should be able to create BaseRoundedForm class that inherits from RadForm and achieve the rounded corners that you need.

I hope this information helps. If you have any other questions, please let me know.
