Winform 2.0中的Strip控件

including MenuStrip, ToolStrip, StatusStrip, and ContextMenuStrip

The new strip controls improve on MainMenu, ToolBar, StatusBar, and ContextMenu in several key ways, including:

• A consistent API to all strip controls
• Improved design-time experience
• Allowing adjacent strip controls to be repositioned with respect to one another, as well as repositioned to the top, right, bottom, and left of the host form's client area
• Contemporary look of Office 2003 and Windows themes
• Ability to host a rich set of child controls, such as dropdown lists, labels, menus, and textboxes
• Rendering support that simplifies custom painting coding

While MainMenu, ToolBar, StatusBar, and ContextMenu are not included by default in the Visual Studio Toolbox, they are still included in the .NET Framework, primarily for backwards compatibility. Of course, the strip controls are located on the Toolbox so you can easily drag them onto your form. Through the Designer, you can add a variety of controls to each strip control

Figure 11 Key Strip Control Property Configurations

Property	Description
AllowItemReorder	Users can reposition strip items by setting this property to True. The user needs to press Alt before repositioning (not for ContextMenuStrip).
ShowItemToolTips	Sets whether strip items can also display tool tips (not for MenuStrip or Context MenuStrip).
Dock	Specifies the form edge to line the strip control up against or fill.
RenderMode	Strip controls support three render modes: System: rendered with colors from the system palette. Professional: rendered according to the current Windows Color Scheme—Blue, Olive Green, or Silver. ManagerRenderMode: rendered using the Windows Theme sensitive ToolStripRenderer and is the default. Custom is currently unsupported.
SizingGrip	Specifies whether the form sizing grip should be shown or hidden (StatusStrip only).
GripStyle	Specifies whether a MenuStrip or ToolStrip displays a grip allowing it to be repositioned.
CanOverflow	When the form becomes narrower than a strip control, this option specifies how to visually represent strip items that are hidden by the overlap, either hidden if False or accessible via a dropdown at the end of the strip control if True.
