DevExpress 动态换肤

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>
