WPF 功能区以编程方式折叠和展开
在最新（2010 年 10 月）的 WPF 功能区库中，存在一个用于最小化/最大化（或折叠/展开，如果您愿意）功能区控件的菜单项。
有谁知道是否还有一种方法可以挂钩控制此行为的事件，以便可以从单独的 UI 以编程方式控制它？ 或者，更好的是，有没有办法像 2010 Office 应用程序那样在功能区中显示折叠/展开按钮？
With the latest (October 2010) WPF Ribbon libraries, there exists a menu item to minimize/maximize (or collapse/expand, if you prefer) the ribbon control.
Does anyone know if there's also a way to hook into the events that control this behaviour so that it could be controlled programmatically from separate UI?
Or, better yet, is there a way to get a collapse/expand button to display in the ribbon like the 2010 Office apps do?

您可以使用布尔属性
Ribbon类上的 IsMinimized据我所知，默认模板没有像 Office 那样的显示/隐藏按钮，但修改模板（使用 Blend）来添加一个应该不会太难。
You can use the boolean property
IsMinimizedon theRibbonclass to show/hide the ribbon itself. It is a dependency property, so you can bind to its value to support the scenarios you describe.As far as I know, the default template does not have a show/hide button, like Office does, but it shouldn't be too hard to modify the template (using Blend) to add one.
如果您需要知道栏何时最小化（当您双击选项卡标题时会发生这种情况），您可以挂钩
IsMinimizedChanged事件，但是呃..它丢失了。希望它是一个 DependencyProperty，这样您就可以通过以下方式成功挂钩任何 DependencyProperty 更改：
DependencyPropertyDescriptor.FromProperty(Ribbon.IsMinimizedProperty, typeof(Ribbon))
.AddValueChanged(ribbon, (o, args) => /* 你的代码在这里 */);
我想做的（因此到达这里）是防止它在双击标题时最小化，所以我最终使用此代码：
DependencyPropertyDescriptor.FromProperty(Ribbon.IsMinimizedProperty, typeof(Ribbon)).AddValueChanged(ribbon, (o, args) =>ribbon.IsMinimized = false);
不是那么花哨，但完成了工作。
If what you need is know when the bar gets minimized (this happens when you double click a tab header) you could hook to the
IsMinimizedChangedevent, but er.. it is missing.Hopefully it is a
DependencyPropertyso you can successfully hook to anyDependencyPropertychange this way:DependencyPropertyDescriptor.FromProperty(Ribbon.IsMinimizedProperty, typeof(Ribbon)).AddValueChanged(ribbon, (o, args) => /* your code here */);
What I wanted to do (and hence got here) is to prevent it from minimizing when double clicking the header so I ended up using this code:
DependencyPropertyDescriptor.FromProperty(Ribbon.IsMinimizedProperty, typeof(Ribbon)).AddValueChanged(ribbon, (o, args) => ribbon.IsMinimized = false);
Is not so fancy but gets the job done.
添加一个切换按钮（简单按钮，根据请求的操作将其内容设置为 v 或 ^），然后您可以在按钮单击中使用 ContentControl 来满足您的要求：
Use contentControl.Visibility = System.Windows.Visibility.Visible;为了最大化功能区
Add a toggle button(simple button and set its content to v or ^ depending upon the operation requested) and then you can use ContentControl in button click to fulfill your requirement:
Use contentControl.Visibility = System.Windows.Visibility.Visible; in order to maximize the ribbon
