Wpf DevXPress BarManager SaveLayoutToStream

我有一个充满DevExpress控件的窗口。突出的控件是一个DockLayoutManager，其中包含一个选项卡组。选项卡组包含以下选项之一：透视表控件或网格控件。围绕此控件的是其他可固定窗口以及窗口顶部的项目菜单

我想通过调用BarManager对象上的SaveLayoutToStream来保存项菜单栏的布局

当且仅当突出控件的布局与原始布局（即设计时）相同时，此功能才会成功完成。如果我拖动“个人”选项卡并将其停靠在DockLayoutManager中，则会出现以下异常：

Exception of type 'DevExpress.Xpf.Core.Serialization.DuplicateSerializationIDException' was thrown.

我们已经查看了调用堆栈，甚至无法想象是什么导致出现此问题。请将显示此问题的示例项目发布到。我们将研究问题出现的原因并解决它。

如果在布局中使用相同类型的对象，请为所有对象指定DXSerializer.SerializationID属性

比如说

<Window x:Class="WpfApplication.MainWindow"
        xmlns:core="http://schemas.devexpress.com/winfx/2008/xaml/core"
        xmlns:dxdo="http://schemas.devexpress.com/winfx/2008/xaml/docking"

<dxdo:DockLayoutManager Name="FilterGridDockLayoutManager" core:DXSerializer.SerializationID="dock1" >
