我正在使用 Microsoft.Windows.Controls.Ribbon，我想保存和加载 QuickAccessToolBar。
如何在功能区控件中找到 QuickAccessToolBar 项目？
这是我保存功能区 QuickAccessToolBar 的想法
- OnClosing 应用程序：获取 QuickAccessToolBar 项目，并在 Ribbon 项目上定位。然后序列化
- OnLoad : 读取序列化对象，并添加插入项 QuickAccessToolBar

最后我做到了！
我基于WPF Ribbon Sample来保存/加载。它使用 datacontext 来本地化 RibbonControl 上的控件，我不喜欢，所以我使用 QuickAccessToolBarId 来本地化控件。
这是解决方案： - OnClosing Application： 我保存 QuickAccessToolBar，通过 QuickAccessToolBar 搜索功能区控件上的项目，并保存路径。注意：当项目在应用程序菜单中时，第一个路径是 -1.A - OnLoadApplication：
加载项目，并通过路径搜索功能区控件。
这是代码：

要序列化的类：
public class QatItem {
public QatItem()
{
}
public QatItem(int qatbIdHashCode)
{
QuickAccessToolBarIdHashCode = qatbIdHashCode;
}
public Int32Collection ControlIndices
{
get
{
if (_controlIndices == null)
{
_controlIndices = new Int32Collection();
}
return _controlIndices;
}
set
{
_controlIndices = value;
}
}
Int32Collection _controlIndices;
[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public int QuickAccessToolBarIdHashCode { get; set; }
//Is only for load
[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public Control Owner { get; set; }
}
public class QatItemCollection : List<QatItem>
{
}
这是从窗口保存/加载的代码
RibbonHelper helper;
protected override void OnClosing(CancelEventArgs e)
{
helper.Save();
base.OnClosing(e);
}
private void RibbonWindow_Loaded(object sender, RoutedEventArgs e)
{
helper = new RibbonHelper(ribbon);
helper.Load();
}
