Button ControlTemplate and rounded corners

问题

I have a controltemplate for buttons. I want to make the buttons with rounded corners. How should I do this?

I tried CornerRadius for button in the Border but it doesn't work. The background of the button has set to an image that has corner borders and the button looks akward as I can't set the corners for the button.

Try the following:

<Style x:Key="GlassButton" TargetType="{x:Type Button}">
    <Setter Property="FontSize" Value="42" />
    <Setter Property="Foreground" Value="White" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Button}">
                <Border x:Name="border"
                        CornerRadius="25"
                        BorderThickness="4"
                        Background="#AA000000"
                        BorderBrush="Red"
                        RenderTransformOrigin="0.5,0.5">
                    <ContentPresenter x:Name="ButtonContentPresenter"
                                      VerticalAlignment="Center"
                                      HorizontalAlignment="Center" />
                </Border>

                <ControlTemplate.Triggers>
                    <Trigger Property="IsMouseOver" Value="True">
                        <Setter TargetName="border" Property="BorderBrush" Value="#FF4788c8" />
                        <Setter Property="Foreground" Value="#FF4788c8" />
                    </Trigger>
                    <Trigger Property="IsPressed" Value="True">
                        <Setter Property="Background">
                            <Setter.Value>
                                <LinearGradientBrush StartPoint="0,0" EndPoint="0,1">
                                    <GradientStop Color="#FFFFD190" Offset="0.35" />
                                    <GradientStop Color="Orange" Offset="0.95" />
                                    <GradientStop Color="#FFFFD190" Offset="1" />
                                </LinearGradientBrush>
                            </Setter.Value>
                        </Setter>
                        <Setter TargetName="content" Property="RenderTransform">
                            <Setter.Value>
                                <TranslateTransform Y="1.0" />
                            </Setter.Value>
                        </Setter>
                    </Trigger>
                    <Trigger Property="IsDefaulted" Value="True">
                        <Setter TargetName="border" Property="BorderBrush" Value="#FF282828" />
                    </Trigger>
                    <Trigger Property="IsFocused" Value="True">
                        <Setter TargetName="border" Property="BorderBrush" Value="#FF282828" />
                    </Trigger>
                    <Trigger Property="IsEnabled" Value="False">
                        <Setter TargetName="border" Property="Opacity" Value="0.7" />
                        <Setter Property="Foreground" Value="Gray" />
                    </Trigger>

                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>
