按钮如何删除边框

Question

I have a question about dat wpf buttons. In my app I have fore example some code

<Button x:Name="SukaKnopka" VerticalAlignment="Top" HorizontalAlignment="Right" Background="Black" MaxHeight="20" MaxWidth="20" BorderBrush="Black">
    <Image Source="ButtonsImages/close_btn.png" Stretch="Fill"/>
</Button>

All is fine but there is some little border around this button =( I have tryed BorderBrush="{x:Null}" but the border again present. (This border highlights if MouseOver)

Answer 1

As far as I understand it, a lot of WPF controls are fully defined in their styles. So even if you specify a different border on a Button , for example; the Button 's existing styles will override whatever you have specified. To overcome this, you must create a ControlTemplate .

Answer 2

    <Button>
        <Button.Resources>
            <Style TargetType="Border">
                <Setter Property="BorderThickness" Value="0" />
            </Style>
        </Button.Resources>
    </Button>

This should do the trick. It will set every BorderThickness or every Border inside the button to 0.

slade is right, try modifying what you have to look more like the following and it should give you what you want.

<Button x:Name="SukaKnopka" VerticalAlignment="Top" HorizontalAlignment="Right" Background="Black" MaxHeight="20" MaxWidth="20" BorderBrush="Black">
<Button.Template>
    <ControlTemplate>
            <Image Source="ButtonsImages/close_btn.png" Stretch="Fill"/> 
    </ControlTemplate>
</Button.Template>
</Button>

Been a while since I did any "real" WPF, but does

BorderThickness="0,0,0,0"

work?
