Answer 1

Try this

<Button BorderThickness="0"  
    Style="{StaticResource {x:Static ToolBar.ButtonStyleKey}}" >...

Answer 2

What you have to do is something like this:

<Button Name="MyFlatImageButton"
        Background="Transparent"
        BorderBrush="Transparent"
        BorderThickness="0" 
        Padding="-4">
   <Image Source="MyImage.png"/>
</Button>

Hope this is what you were looking for.

Edit: Sorry, forgot to mention that if you want to see the button-border when you hover over the image, all you have to do is skip the Padding="-4".

You may already know that putting your Button inside of a ToolBar gives you this behavior, but if you want something that will work across ALL current themes with any sort of predictability, you'll need to create a new ControlTemplate.

Prashant's solution does not work with a Button not in a toolbar when the Button has focus. It also doesn't work 100% with the default theme in XP -- you can still see faint gray borders when your container Background is white.

I don't know why others haven't pointed out that this question is duplicated with this one with accepted answer.

I quote here the solution: You need to override the ControlTemplate of the Button:

<Button Content="save" Name="btnSaveEditedText" 
                Background="Transparent" 
                Foreground="White" 
                FontFamily="Tw Cen MT Condensed" 
                FontSize="30" 
                Margin="-280,0,0,10"
                Width="60"
                BorderBrush="Transparent"
                BorderThickness="0">
    <Button.Template>
        <ControlTemplate TargetType="Button">
             <ContentPresenter Content="{TemplateBinding Content}"/>
        </ControlTemplate>
    </Button.Template>  
</Button>

Answer 5

You can use Hyperlink instead of Button, like this:

        <TextBlock>
            <Hyperlink TextDecorations="{x:Null}">
            <Image Width="16"
                   Height="16"
                   Margin="3"
                   Source="/YourProjectName;component/Images/close-small.png" />
            </Hyperlink>
        </TextBlock>

Answer 6

Why don't you set both Background & BorderBrush by same brush

 <Style TargetType="{x:Type Button}" >
        <Setter Property="Background" Value="{StaticResource marginBackGround}"></Setter>
        <Setter Property="BorderBrush" Value="{StaticResource marginBackGround}"></Setter>            
 </Style>

<LinearGradientBrush  x:Key="marginBackGround" EndPoint=".5,1" StartPoint="0.5,0">
    <GradientStop Color="#EE82EE" Offset="0"/>
    <GradientStop Color="#7B30B6" Offset="0.5"/>
    <GradientStop Color="#510088" Offset="0.5"/>
    <GradientStop Color="#76209B" Offset="0.9"/>
    <GradientStop Color="#C750B9" Offset="1"/>
</LinearGradientBrush>
