#437 – Showing Rounded Corners on a Border

You can set a Border element to show rounded corners by using the CornerRadius property.  If specified, this property indicates the radius, in device independent units, of one or more of the corners of a Border.

        <Grid>
            <Border Margin="10" BorderBrush="DarkGray" BorderThickness="1" CornerRadius="5">
                <StackPanel Orientation="Vertical" Margin="5" Visibility="Visible">
                    <Label Content="Rounded corners are all around us"/>
                    <Button Content="Push Me" Padding="30,5" HorizontalAlignment="Center"/>
                </StackPanel>
            </Border>
        </Grid>

You can also specify different radii for each corner.

            <Border Margin="10" BorderBrush="DarkGray" BorderThickness="1" CornerRadius="4,8,32,16">
