DevExpress主题允许您在代码中使用调色板颜色作为资源，您可以使用DevExpress主题颜色绘制自定义控件，以使应用程序的样式保持一致。
您可以将每个调色板颜色用作颜色 (PaletteColorThemeKey) 或画笔 (PaletteBrushThemeKey)。
MainWindow.xaml
<ThemedWindow ...
xmlns:dxi="http://schemas.devexpress.com/winfx/2008/xaml/core/internal"
xmlns:dxt="http://schemas.devexpress.com/winfx/2008/xaml/themes">
<Button Background="{dxi:ThemeResource {dxt:PaletteBrushThemeKey ResourceKey=Button.Background}}"
BorderBrush="{dxi:ThemeResource {dxt:PaletteBrushThemeKey ResourceKey=Border}}"
BorderThickness="1" />
</ThemedWindow>
示例
下面的代码示例演示了如何将VS2017Blue主题的Border调色板资源绑定到自定义控件的BorderBrush属性：
CustomControls.cs
using System.Windows;
using System.Windows.Controls;
namespace WpfApp36 {
public class CustomControl1 : Control {
static CustomControl1() {
DefaultStyleKeyProperty.OverrideMetadata(typeof(CustomControl1), new FrameworkPropertyMetadata(typeof(CustomControl1)));
}
public string Text {
get { return (string)GetValue(TextProperty); }
set { SetValue(TextProperty, value); }
}
public static readonly DependencyProperty TextProperty =
DependencyProperty.Register("Text", typeof(string), typeof(CustomControl1), new PropertyMetadata(null));
}
}
