Avoiding a flashing WPF button

I am writing a program using WPF (C #). I use a few buttons. After clicking on it, the Anny! Button will flash Its color fades from background color to aqua color (light blue). It does not stop flashing when I press another button (then this button starts flashing !!!). This is mistake? is it related to my visual studio?

How can I fix this problem?

First, you can try setting the Focusable button to False . However, this will be a problem if you use keyboard navigation. However, I found this Window.Resource XAML code:

 <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, when you want to apply a custom button style, set the Style button to:

 <Button Style="{DynamicResource BoringButtonStyle}"/>

You can override the Button template to remove the default Themed(Aero) style.

Something like this would be a good place to start.

 <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>
