How to avoid flashing button WPF
提问by Babak.Abad
I'm writing a program using WPF(c#). I use several buttons. Anny button start flashing after clicking on it! Its color fading from background color to aqua (light blue) color. It does not stop flashing while I click another button( then this button starts flashing!!!). Is it a bug? is it related to my visual studio?
我正在使用 WPF(c#) 编写程序。我使用了几个按钮。点击后Anny按钮开始闪烁！它的颜色从背景颜色渐变为浅绿色（浅蓝色）。当我点击另一个按钮时它不会停止闪烁（然后这个按钮开始闪烁！！！）。这是一个错误吗？它与我的视觉工作室有关吗？
How can I fix this problem?

Firstly, you could try setting the button Focusableto False. However, this will be a problem if you use keyboard navigation. I did however find this Window.ResourceXAML code:
首先，您可以尝试将按钮设置Focusable为False。但是，如果您使用键盘导航，这将是一个问题。但是我确实找到了这个Window.ResourceXAML 代码：
<Window.Resources>
<Style x:Key="ButtonFocusVisual">
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Rectangle Margin="2" SnapsToDevicePixels="true" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<LinearGradientBrush x:Key="ButtonNormalBackground" EndPoint="0,1" StartPoint="0,0">
<GradientStop Color="#F3F3F3" Offset="0"/>
<GradientStop Color="#EBEBEB" Offset="0.5"/>
<GradientStop Color="#DDDDDD" Offset="0.5"/>
<GradientStop Color="#CDCDCD" Offset="1"/>
</LinearGradientBrush>
<SolidColorBrush x:Key="ButtonNormalBorder" Color="#FF707070"/>
<Style x:Key="BoringButtonStyle" TargetType="{x:Type Button}">
<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 Button}">
<Microsoft_Windows_Themes:ButtonChrome x:Name="Chrome" BorderBrush="{TemplateBinding BorderBrush}" Background="{TemplateBinding Background}" RenderMouseOver="{TemplateBinding IsMouseOver}" RenderPressed="{TemplateBinding IsPressed}" RenderDefaulted="{TemplateBinding IsDefaulted}" SnapsToDevicePixels="true">
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Microsoft_Windows_Themes:ButtonChrome>
<ControlTemplate.Triggers>
<Trigger Property="ToggleButton.IsChecked" Value="true">
<Setter Property="RenderPressed" TargetName="Chrome" Value="true"/>
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Foreground" Value="#ADADAD"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Then whenever you want to apply the custom button style, set the button Styleto:
然后每当您想应用自定义按钮样式时，将按钮设置Style为：
<Button Style="{DynamicResource BoringButtonStyle}"/>

You can override the Buttontemplate to remove the default Themed(Aero)style
您可以覆盖Button模板以删除默认Themed(Aero)样式
Something like this will be a good place to start.
像这样的事情将是一个很好的起点。
<Style TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="Border" CornerRadius="2" BorderThickness="1" Background="{x:Static SystemColors.ControlBrush}" BorderBrush="{x:Static SystemColors.ControlDarkDarkBrush}">
<ContentPresenter Margin="2" HorizontalAlignment="Center" VerticalAlignment="Center" RecognizesAccessKey="True"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsKeyboardFocused" Value="True">
<Setter TargetName="Border" Property="BorderBrush" Value="{x:Static SystemColors.ControlBrush}" />
<Setter TargetName="Border" Property="BorderBrush" Value="{x:Static SystemColors.ControlDarkDarkBrush}" />
</Trigger>
<Trigger Property="IsDefaulted" Value="True">
<Setter TargetName="Border" Property="BorderBrush" Value="{x:Static SystemColors.ControlBrush}" />
<Setter TargetName="Border" Property="BorderBrush" Value="{x:Static SystemColors.ControlDarkDarkBrush}" />
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="Border" Property="Background" Value="{x:Static SystemColors.ActiveCaptionBrush}" />
<Setter TargetName="Border" Property="BorderBrush" Value="{x:Static SystemColors.ControlDarkDarkBrush}" />
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter TargetName="Border" Property="Background" Value="{x:Static SystemColors.ActiveCaptionBrush}" />
<Setter TargetName="Border" Property="BorderBrush" Value="{x:Static SystemColors.ControlDarkDarkBrush}" />
</Trigger>
<Trigger Property="IsEnabled" Value="False">
<Setter TargetName="Border" Property="Background" Value="#EEEEEE" />
<Setter TargetName="Border" Property="BorderBrush" Value="#AAAAAA" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
