How do you completely remove the button border in

Question

I'm trying to create a button that has an image in it and no border - just like the Firefox toolbar buttons before you hover over them and see the full button.

I've tried setting the BorderBrush to Transparent, BorderThickness to 0, and also tried BorderBrush="{x:Null}", but you can still see the outline of the button.

Answer 1

You may have to change the button template, this will give you a button with no frame what so ever, but also without any press or disabled effect:

    <Style x:Key="TransparentStyle" TargetType="{x:Type Button}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Border Background="Transparent">
                        <ContentPresenter/>
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

And the button:

<Button Style="{StaticResource TransparentStyle}"/>

Try this

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

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>

Programmatically, you can do this:

btn.BorderBrush = new SolidColorBrush(Colors.Transparent);

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>
