Progress Telerik UI for WinForms
Telerik TitleBar is a separate RadControl, which can be dropped on any standard Form, ShapedForm or RadForm to provide the form with a set of customizable maximize, minimize and close buttons. Each button is a RadButtonElement that includes properties to control its text, image, and layout. The title bar can be manually skinned to match the form's UI, or can use one of the preset themes.
In addition, the control supports the Help button.
