Introduction
Un style permet la modification complète de l'apparence visuelle d'un contrôle WPF. Voici quelques exemples de styles de base et une introduction aux dictionnaires de ressources et à l'animation.
Styling d'un bouton
Le moyen le plus simple de créer un style consiste à copier un style existant et à le modifier.
Créez une fenêtre simple avec deux boutons:
<Window x:Class="WPF_Style_Example.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d" ResizeMode="NoResize"
Title="MainWindow"
Height="150" Width="200">
<Grid>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Button Margin="5" Content="Button 1"/>
<Button Margin="5" Grid.Row="1" Content="Button 2"/>
</Grid>
Dans Visual Studio, la copie peut être effectuée en cliquant avec le bouton droit sur le premier bouton de l'éditeur et en choisissant "Modifier une copie ..." dans le menu "Modifier le modèle".
Définir dans "Application".
L'exemple suivant montre un modèle modifié pour créer un bouton ellipse:
<Style x:Key="ButtonStyle1" TargetType="{x:Type Button}">
<Setter Property="FocusVisualStyle" Value="{StaticResource FocusVisual}"/>
<Setter Property="Background" Value="{StaticResource Button.Static.Background}"/>
<Setter Property="BorderBrush" Value="{StaticResource Button.Static.Border}"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="HorizontalContentAlignment" Value="Center"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="Padding" Value="1"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Grid>
<Ellipse x:Name="ellipse" StrokeThickness="{TemplateBinding BorderThickness}" Stroke="{TemplateBinding BorderBrush}" Fill="{TemplateBinding Background}" SnapsToDevicePixels="true"/>
<ContentPresenter x:Name="contentPresenter" Focusable="False" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsDefaulted" Value="true">
<Setter Property="Stroke" TargetName="ellipse" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Fill" TargetName="ellipse" Value="{StaticResource Button.MouseOver.Background}"/>
<Setter Property="Stroke" TargetName="ellipse" Value="{StaticResource Button.MouseOver.Border}"/>
</Trigger>
<Trigger Property="IsPressed" Value="true">
<Setter Property="Fill" TargetName="ellipse" Value="{StaticResource Button.Pressed.Background}"/>
<Setter Property="Stroke" TargetName="ellipse" Value="{StaticResource Button.Pressed.Border}"/>
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Fill" TargetName="ellipse" Value="{StaticResource Button.Disabled.Background}"/>
<Setter Property="Stroke" TargetName="ellipse" Value="{StaticResource Button.Disabled.Border}"/>
<Setter Property="TextElement.Foreground" TargetName="contentPresenter" Value="{StaticResource Button.Disabled.Foreground}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Le résultat:
Style appliqué à tous les boutons
En prenant l'exemple précédent, la suppression de l'élément x: Key du style applique le style à tous les boutons de la portée de l'application.
<Style TargetType="{x:Type Button}">
<Setter Property="FocusVisualStyle" Value="{StaticResource FocusVisual}"/>
<Setter Property="Background" Value="{StaticResource Button.Static.Background}"/>
<Setter Property="BorderBrush" Value="{StaticResource Button.Static.Border}"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="HorizontalContentAlignment" Value="Center"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="Padding" Value="1"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Grid>
<Ellipse x:Name="ellipse" StrokeThickness="{TemplateBinding BorderThickness}" Stroke="{TemplateBinding BorderBrush}" Fill="{TemplateBinding Background}" SnapsToDevicePixels="true"/>
<ContentPresenter x:Name="contentPresenter" Focusable="False" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsDefaulted" Value="true">
<Setter Property="Stroke" TargetName="ellipse" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Fill" TargetName="ellipse" Value="{StaticResource Button.MouseOver.Background}"/>
<Setter Property="Stroke" TargetName="ellipse" Value="{StaticResource Button.MouseOver.Border}"/>
</Trigger>
<Trigger Property="IsPressed" Value="true">
<Setter Property="Fill" TargetName="ellipse" Value="{StaticResource Button.Pressed.Background}"/>
<Setter Property="Stroke" TargetName="ellipse" Value="{StaticResource Button.Pressed.Border}"/>
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Fill" TargetName="ellipse" Value="{StaticResource Button.Disabled.Background}"/>
<Setter Property="Stroke" TargetName="ellipse" Value="{StaticResource Button.Disabled.Border}"/>
<Setter Property="TextElement.Foreground" TargetName="contentPresenter" Value="{StaticResource Button.Disabled.Foreground}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Notez que le style ne doit plus être spécifié pour les boutons individuels:
<Window x:Class="WPF_Style_Example.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d" ResizeMode="NoResize"
Title="MainWindow"
Height="150" Width="200">
<Grid>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Button Margin="5" Content="Button 1"/>
<Button Margin="5" Grid.Row="1" Content="Button 2"/>
</Grid>
Les deux boutons sont maintenant stylés.
Créer un ComboBox
En commençant par les ComboBox suivants:
<Window x:Class="WPF_Style_Example.ComboBoxWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d" ResizeMode="NoResize"
Title="ComboBoxWindow"
Height="100" Width="150">
<StackPanel>
<ComboBox Margin="5" SelectedIndex="0">
<ComboBoxItem Content="Item A"/>
<ComboBoxItem Content="Item B"/>
<ComboBoxItem Content="Item C"/>
</ComboBox>
<ComboBox IsEditable="True" Margin="5" SelectedIndex="0">
<ComboBoxItem Content="Item 1"/>
<ComboBoxItem Content="Item 2"/>
<ComboBoxItem Content="Item 3"/>
</ComboBox>
</StackPanel>
Cliquez avec le bouton droit sur le premier ComboBox dans le concepteur, choisissez "Modifier le modèle -> Modifier une copie". Définissez le style dans la portée de l'application.
Il y a 3 styles créés:
ComboBoxToggleButton
ComboBoxEditableTextBox
ComboBoxStyle1
Et 2 modèles:
ComboBoxTemplate
ComboBoxEditableTemplate
Exemple de modification du style ComboBoxToggleButton :

Cela crée un ComboBox arrondi qui met en surbrillance orange au passage de la souris et devient rouge lorsque vous appuyez dessus.
Notez que cela ne changera pas la liste déroulante modifiable en dessous; modification qui nécessite de modifier le style ComboBoxEditableTextBox ou le ComboBoxEditableTemplate .
Création d'un dictionnaire de ressources
Avoir beaucoup de styles dans App.xaml deviendra rapidement complexe, de sorte qu'ils peuvent être placés dans des dictionnaires de ressources séparés.
Pour utiliser le dictionnaire, il doit être fusionné avec App.xaml. Ainsi, dans App.xaml, après la création du dictionnaire de ressources:
<Application
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Class="WPF_Style_Example.App"
StartupUri="MainWindow.xaml">
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="ResourceDictionaries/Dictionary1.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
</Application>
De nouveaux styles peuvent maintenant être créés dans Dictionary1.xaml et ils peuvent être référencés comme s'ils étaient dans App.xaml. Après avoir créé le projet, l'option apparaît également dans Visual Studio lors de la copie d'un style pour le localiser dans le nouveau dictionnaire de ressources.
Bouton Style DoubleAnimation
La Window suivante a été créée:
<Window x:Class="WPF_Style_Example.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d" ResizeMode="NoResize"
Title="MainWindow"
Height="150" Width="250">
<Grid>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Button Margin="5" Content="Button 1" Width="200"/>
<Button Margin="5" Grid.Row="1" Content="Button 2" Width="200"/>
</Grid>
Un style (créé dans App.xaml) a été appliqué aux boutons, qui anime la largeur de 200 à 100 lorsque la souris entre dans le contrôle et de 100 à 200 quand elle quitte:
<Style TargetType="{x:Type Button}">
<Setter Property="FocusVisualStyle" Value="{StaticResource FocusVisual}"/>
<Setter Property="Background" Value="{StaticResource Button.Static.Background}"/>
<Setter Property="BorderBrush" Value="{StaticResource Button.Static.Border}"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="HorizontalContentAlignment" Value="Center"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="Padding" Value="1"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Grid Background="White">
<Border x:Name="border" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="true">
<ContentPresenter x:Name="contentPresenter" Focusable="False" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Border>
</Grid>
<ControlTemplate.Triggers>
