DevExpress主題允許您在代碼中使用調色板顏色作爲資源,您可以使用DevExpress主題顏色繪製自定義控件,以使應用程序的樣式保持一致。
您可以將每個調色板顏色用作顏色 (PaletteColorThemeKey) 或畫筆 (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
下面的代碼示例演示瞭如何將VS2017Blue主題的Border調色板資源綁定到自定義控件的BorderBrush屬性:
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)); } }
MainWindow.xaml
<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:local="clr-namespace:WpfApp36" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="WpfApp36.MainWindow"> <Grid> <Grid.RowDefinitions> <RowDefinition/> </Grid.RowDefinitions> <local:CustomControl1 Grid.Row="0" Margin="5" Text="Custom control binding to a theme name"/> </Grid> </Window> CustomControl1_Resources.xaml <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:dxt="http://schemas.devexpress.com/winfx/2008/xaml/core/themekeys" xmlns:local="clr-namespace:WpfApp36"> <Style TargetType="{x:Type local:CustomControl1}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type local:CustomControl1}"> <Border BorderBrush="{DynamicResource {dxt:PaletteBrushThemeKey ResourceKey=Border, ThemeName=VS2017Blue}}" BorderThickness="3"> <TextBlock Foreground="Black" HorizontalAlignment="Center" Text="{TemplateBinding Text}" VerticalAlignment="Center"/> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> </ResourceDictionary> App.xaml <Application x:Class="WpfApp36.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" StartupUri="MainWindow.xaml"> <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/WPFApp36;component/CustomControl1_Resources.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> </Application>
添加 XPF.Core 和 VS2017Blue 主題引用來運行這個項目。
