Saving and Restoring the Layout of Bars

• May 22, 2020

 

The layout of bars can be saved to a data store (for instance, a stream), and then restored from this data store, overriding the changes made since the layout was saved. This document provides more information on this topic.

Saving and Restoring the Layout of Bars

The layout of bars can be saved to a data store manually, using the BarManager.SaveLayoutToStream method. To restore the layout, use the BarManager.RestoreLayoutFromStream method.

NOTE

For the layout of bars to be saved, set the DevExpress.Xpf.Core.Serialization.DXSerializer.DXSerializer.SerializationID attached property for a BarManager to any object (for example, a string).

XAML

xmlns:dx="http://schemas.devexpress.com/winfx/2008/xaml/core"
<!--...-->
<dxb:BarManager x:Name="barManager1" dx:DXSerializer.SerializationID="barManager">
<!--...-->

C#

System.IO.Stream str;
// Create and save the layout of bars to a new memory stream
str = new System.IO.MemoryStream();
barManager1.SaveLayoutToStream(str);
str.Seek(0, System.IO.SeekOrigin.Begin);
//...
// Load the layout of bars from the memory stream
barManager1.RestoreLayoutFromStream(str);
str.Seek(0, System.IO.SeekOrigin.Begin);

VB.NET

Dim str As System.IO.Stream
' Create and save the layout of bars to a new memory stream
str = New System.IO.MemoryStream()
BarManager1.SaveLayoutToStream(str)
str.Seek(0, System.IO.SeekOrigin.Begin)
' ..
' Load the layout of bars from the memory stream
BarManager1.RestoreLayoutFromStream(str)
str.Seek(0, System.IO.SeekOrigin.Begin)
