DevExpress BarManager SaveLayoutToStream

Question

我有一个全是DevExpress控件的窗口。突出的控件是一个包含透视表( TabbedGroup )的标签(标签包含以下控件之一:透视表控件或网格控件)。围绕此控件的是其他可停靠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来保存项目菜单栏的布局。

当且仅当突出控件的布局与原始布局相同时(即在设计时)，此函数才会成功完成。如果我拖动各个选项卡并将它们停靠在DockLayoutManager中，则会出现以下异常：

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

我们已经检查了callstack，甚至无法想象是什么导致了这个问题的出现。请将显示此问题的示例项目发布到DevExpress support center。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，请为所有对象分配DXSerializer.SerializationID属性

例如

<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" >
