Answer 1

One of the great fetatures of WPF is the ability to leverage the behavior of a control while completely swapping the look of that control.You can just delete the chrome altogether and create a custom appearence that matches your requirement.

Sample

 <Style x:Key="NoChromeButton" TargetType="{x:Type Button}">
        <Setter Property="Background" Value="Transparent"/>
        <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}">
                    <Grid x:Name="Chrome" Background="{TemplateBinding Background}" SnapsToDevicePixels="true">
                        <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                    </Grid>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsEnabled" Value="false">
                            <Setter Property="Foreground" Value="#ADADAD"/>
                            <Setter Property="Opacity" TargetName="Chrome" Value="0.5"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

if you want to just avoid the WhiteBorder you have to just change the BorderBrush=Transparent

<Microsoft_Windows_Themes:ButtonChrome x:Name="Chrome" SnapsToDevicePixels="true" 
                        Background="{TemplateBinding Background}" BorderBrush="Transparent"
                         RenderDefaulted="{TemplateBinding IsDefaulted}" RenderMouseOver="{TemplateBinding IsMouseOver}"
                          RenderPressed="{TemplateBinding IsPressed}">
                            <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" RecognizesAccessKey="True"/>
                        </Microsoft_Windows_Themes:ButtonChrome>

If you want to modify some other things you have to create your own ControlTemplate

here they have different button templates

You should not try to customize ButtonChrome. *Chrome classes are theme-specific, i.e. they contain implementation of a specific windows theme and you cannot override it. Look at the declaration of the "Microsoft_Windows_Themes" namespace in your resource dictionary - it probably contains something like PresentationFramework.Aero...

What you should do in your custom templates is use usual Border instead of ButtonChrome and define triggers that will change its background, etc. when the button is pressed or hovered.

Here is an example:

<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="{StaticResource ButtonNormalForeground}" />
<Setter Property="HorizontalContentAlignment"
        Value="Center" />
<Setter Property="VerticalContentAlignment"
        Value="Center" />
<Setter Property="Padding"
        Value="5,2,5,2" />
<Setter Property="Template">
    <Setter.Value>
        <ControlTemplate TargetType="{x:Type ButtonBase}">
            <Border Name="Chrome"
                    Background="{TemplateBinding Background}"
                    BorderBrush="{TemplateBinding BorderBrush}"
                    BorderThickness="{TemplateBinding BorderThickness}"
                    SnapsToDevicePixels="true"
                    CornerRadius="2">
                <ContentPresenter Margin="{TemplateBinding Padding}"
                                  VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
                                  HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
                                  RecognizesAccessKey="True"
                                  SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" />
            </Border>
            <ControlTemplate.Triggers>
                <Trigger Property="IsMouseOver"
                         Value="True">
                    <Setter Property="Background"
                            Value="{StaticResource ButtonHoverBackground}" />
                    <Setter Property="Foreground"
                            Value="{StaticResource ButtonHoverForeground}" />
                </Trigger>

                <Trigger Property="IsPressed"
                         Value="True">
                    <Setter Property="Background"
                            Value="{StaticResource ButtonPressedBackground}" />
                    <Setter Property="Foreground"
                            Value="{StaticResource ButtonPressedForeground}" />
                </Trigger>
                <Trigger Property="ToggleButton.IsChecked"
                         Value="True">
                    <Setter Property="Background"
                            Value="{StaticResource ButtonHoverBackground}" />
                    <Setter Property="Foreground"
                            Value="{StaticResource ButtonNormalForeground}" />
                </Trigger>
                <Trigger Property="IsEnabled"
                         Value="false">
                    <Setter Property="Foreground"
                            Value="#ADADAD" />

Answer 4

I realize this is an old thread, but I found it when I was trying to do the same thing and didn't find any great solutions. I thought I'd post what I came up with in case it helps anybody else.

What I wanted was flat buttons that used the normal chrome when moused over. The best way I could find to do this was to cheat and use two ContentPresenters inside a Grid with two rows. One content presenter is inside the normal ButtonChrome and one is inside a Border. Only one grid row is shown at a time and the setter in the IsMouseOver trigger determines which one is shown.

<Window.Resources>
    <Style x:Key="ButtonFocusVisual">
        <Setter Property="Control.Template">
            <Setter.Value>
                <ControlTemplate>
                    <Rectangle StrokeDashArray="1 2" StrokeThickness="1" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" SnapsToDevicePixels="true" Margin="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="Transparent"/>
    <Style x:Key="ActionButtonStyle" TargetType="{x:Type Button}">
        <Setter Property="FocusVisualStyle" Value="{StaticResource ButtonFocusVisual}"/>
        <Setter Property="Background" Value="{x:Null}"/>
        <Setter Property="BorderBrush" Value="{x:Null}"/>
        <Setter Property="BorderThickness" Value="0"/>
        <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>

An option is also to use an other library like telerik or xceed (also available for free commercial-use). In my solution I created a class an derived it from Xceed.Wpf.Toolkit.Chromes.ButtonChrome (the Microsoft ButtonChrome is sealed). In my ResourceDictionary I implemented an style for Combobox, created by Blend for VS. In the ControlTemplate for the ToggleButton I have implemented following code:

<ControlTemplate TargetType="{x:Type ToggleButton}">
    <p:ButtonChromeManaged x:Name="Chrome"
                           Width="{DynamicResource {x:Static SystemParameters.VerticalScrollBarWidthKey}}"
                           Background="Transparent"
                           BorderBrush="Transparent"
                           CornerRadius="0"
                           SnapsToDevicePixels="true">
        <p:ButtonChromeManaged.Template>
            <ControlTemplate TargetType="{x:Type p:ButtonChromeManaged}">
                <Border Background="Red">
                    <Path x:Name="Arrow"
                          Margin="0,1,0,0"
                          HorizontalAlignment="Center"
                          VerticalAlignment="Center"
                          Data="{StaticResource DownArrowGeometry}"
                          Fill="Black" />
                </Border>
            </ControlTemplate>
        </p:ButtonChromeManaged.Template>

Here you can see only the most impertand stuf. Your DownArrowGeometry and so on, you know to do. I hope this can help someone ;-)
