Progress Telerik UI for WinForms
Thanks to the powerful Telerik Presentation Framework, each RadElement/RadItem (integral parts of all controls in the suite) has built-in support for shapes. Besides predefined shapes, we also offer the ability to create your own—this is where the Shape Editor comes in handy.
The Shape Editor is used to create curved free-form designs for your UI elements on an integrated drawing surface. There is no code involved, keeping the design as simple as possible. The Windows Forms Shape Editor supports both lines and Bezier curves, adding, moving and removing points as well as options to edit each point setting, for complete control over the element's appearance.
