Bonjour,
Je peux me tromper mais cette surbrillance est du au style du boutton par défaut de WPF et je ne pense pas qu'une propriété puisse y changer quelque chose.
Voici le code xaml du style du button par défaut :
<Style x:Key="BaseButtonStyle"
TargetType="{x:Type ButtonBase}">
<Setter Property="FocusVisualStyle"
Value="{StaticResource ButtonFocusVisual}"/>
<Setter Property="Background"
Value="{StaticResource ButtonNormalBackground}"/>
<Setter Property="BorderBrush"
Value="{StaticResource ButtonNormalBorder}"/>
<Setter Property="BorderThickness"
Value="1"/>
<Setter Property="Foreground"
Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
<Setter Property="HorizontalContentAlignment"
Value="Center"/>
<Setter Property="VerticalContentAlignment"
Value="Center"/>
<Setter Property="Padding"
Value="1"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ButtonBase}">
<theme:ButtonChrome Name="Chrome"
Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
RenderDefaulted="{TemplateBinding Button.IsDefaulted}"
RenderMouseOver="{TemplateBinding IsMouseOver}"
RenderPressed="{TemplateBinding IsPressed}"
SnapsToDevicePixels="true">
<ContentPresenter Margin="{TemplateBinding Padding}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
RecognizesAccessKey="True"
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</theme:ButtonChrome>
<ControlTemplate.Triggers>
<Trigger Property="IsKeyboardFocused"
Value="true">
<Setter TargetName="Chrome"
Property="RenderDefaulted"
Value="true"/>
</Trigger>
<Trigger Property="ToggleButton.IsChecked"
Value="true">
<Setter TargetName="Chrome"
Property="RenderPressed"
Value="true"/>
</Trigger>
<Trigger Property="IsEnabled"
Value="false">
<Setter Property="Foreground"
Value="#ADADAD"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Donc dans ton cas il faut redéfinir ton style des boutons (dans mon exemple j'utilise le style aero) :
voici un exemple que tu peux tester :
<Window x:Class="WpfApplication20.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:theme="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Aero"
Title="MainWindow" Height="350" Width="525">
<Grid>
<Grid.Resources>
<Style x:Key="ButtonFocusVisual">
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Rectangle Margin="2"
StrokeThickness="1"
Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"
StrokeDashArray="1 2"
SnapsToDevicePixels="true"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<LinearGradientBrush x:Key="ButtonNormalBackground"
StartPoint="0,0"
EndPoint="0,1">
<LinearGradientBrush.GradientStops>
<GradientStop Color="#F3F3F3"
Offset="0"/>
<GradientStop Color="#EBEBEB"
Offset="0.5"/>
<GradientStop Color="#DDDDDD"
Offset="0.5"/>
<GradientStop Color="#CDCDCD"
Offset="1"/>
</LinearGradientBrush.GradientStops>
</LinearGradientBrush>
<SolidColorBrush x:Key="ButtonNormalBorder"
Color="#FF707070"/>
<Style x:Key="BaseButtonStyle"
TargetType="{x:Type ButtonBase}">
<Setter Property="FocusVisualStyle"
Value="{StaticResource ButtonFocusVisual}"/>
<Setter Property="Background"
Value="{StaticResource ButtonNormalBackground}"/>
<Setter Property="BorderBrush"
Value="{StaticResource ButtonNormalBorder}"/>
<Setter Property="BorderThickness"
Value="1"/>
<Setter Property="Foreground"
Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
<Setter Property="HorizontalContentAlignment"
Value="Center"/>
<Setter Property="VerticalContentAlignment"
Value="Center"/>
<Setter Property="Padding"
Value="1"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ButtonBase}">
<theme:ButtonChrome Name="Chrome"
Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
RenderDefaulted="{TemplateBinding Button.IsDefaulted}"
RenderPressed="{TemplateBinding IsPressed}"
SnapsToDevicePixels="true">
<ContentPresenter Margin="{TemplateBinding Padding}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
RecognizesAccessKey="True"
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</theme:ButtonChrome>
<ControlTemplate.Triggers>
<Trigger Property="ToggleButton.IsChecked"
Value="true">
<Setter TargetName="Chrome"
Property="RenderPressed"
Value="true"/>
</Trigger>
<Trigger Property="IsEnabled"
Value="false">
<Setter Property="Foreground"
Value="#ADADAD"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Grid.Resources>
<Button Content="test" Click="Button_Click" Style="{StaticResource ResourceKey=BaseButtonStyle}"/>
</Grid>
</Window>
et le code C# pour tester si la pression sur le bouton fonctionne bien :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
namespace WpfApplication20
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void Button_Click(object sender, RoutedEventArgs e)
{
MessageBox.Show("test");
}
}
}
Cordialement, Pascal.
