我们都知道Devexpress内置了很多themes，那要怎么在使用时动态更改呢。
下面是方法以：
1、如果你们已经有主题了，那就在XAML中删除类似下下面的语句。
dx:ThemeManager.ThemeName="LightGray"
2、确保你的XAML中Window是引用下面的
<dx:DXWindow
后台也一样：
MainWindow : DXWindow
3、下面就可以读取DevExpress中所有的主题：
comboBoxEdit1.ItemsSource = Theme.Themes;
4、更换应用主题：
ThemeManager.ApplicationThemeName = Theme.Themes[comboBoxEdit1.SelectedIndex].Name;
5、主程序更新布局：
this.UpdateLayout(); //重新布局
下面是Demo的完整代码：
<dx:DXWindow x:Class="theme.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:dx="http://schemas.devexpress.com/winfx/2008/xaml/core" Title="DXApplication" Height="300" Width="400" SnapsToDevicePixels="True" UseLayoutRounding="True" xmlns:dxe="http://schemas.devexpress.com/winfx/2008/xaml/editors" > <dx:DXWindow.Resources> </dx:DXWindow.Resources> <Grid> <dxe:ComboBoxEdit HorizontalAlignment="Left" Margin="64,85,0,0" Name="comboBoxEdit1" VerticalAlignment="Top" Width="150" /> <dxe:TextEdit EditValue="一个中国人" Height="40" Width="200" Margin="64,120,0,0" /> </Grid> </dx:DXWindow>
