DevExpress BarManager SaveLayoutToStream

Question

我有一个完整的DevExpress控件窗口。显着的控制是一个包含TabbedGroup的DockLayoutManager（选项卡包含以下之一：数据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（即在设计时），此功能才能成功完成。如果我拖了个人标签和DockLayoutManager内停靠他们，然后我得到以下异常：

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

Answer 1

我们审查了调用堆栈甚至不能想象什么可能导致此问题的出现。请将显示此问题的示例项目发布到DevExpress support center。我们将研究为什么会出现问题并解决问题。

如果您使用在布局相同类型的对象，分配DXSerializer.SerializationID财产的所有对象

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" >
