DevExpress BarManager SaveLayoutToStream

Question

我有一個完整的DevExpress控件窗口。顯着的控制是一個包含TabbedGroup的DockLayoutManager（選項卡包含以下之一：數據透視表控件或網格控件）。圍繞此控件的是其他可停靠窗口以及窗口頂部的項目菜單。

我想通過調用BarManager對象上的SaveLayoutToStream來保存項目菜單欄的佈局。

當且僅當突出控件的佈局與原始佈局相同（即在設計時），此功能才能成功完成。如果我拖了個人標籤和DockLayoutManager內停靠他們，然後我得到以下異常：

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

我們審查了調用堆棧甚至不能想象什麼可能導致此問題的出現。請將顯示此問題的示例項目發佈到DevExpress support center。我們將研究爲什麼會出現問題並解決問題。

如果您使用在佈局相同類型的對象，分配DXSerializer.SerializationID財產的所有對象

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" >
