ToolStripProfessionalRenderer Class

Note: This class is new in the .NET Framework version 2.0.

Handles the painting functionality for ToolStrip objects, applying a custom palette and a streamlined style.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public class ToolStripProfessionalRenderer : ToolStripRenderer
public class ToolStripProfessionalRenderer extends ToolStripRenderer
public class ToolStripProfessionalRenderer extends ToolStripRenderer

The ToolStripProfessionalRenderer applies a blue-toned, olive green, or silver-toned palette depending on the operating system color scheme selected by the user.

The following code example demonstrates how to create a composite control that mimics the Navigation Pane provided by Microsoft® Outlook®. For a full code listing, see How to: Create a Professionally Styled ToolStrip Control.
