在LongListSelector中设置网格单元的边角半径和边框

Question

我的应用将瓷砖（按钮）加载到每个longlistselector中。因此没有单独的按钮被编码。我正在尝试添加边框和圆角半径，但它根本没有用。边框添加了曲线，但实际的瓷砖不是弯曲的。有没有办法绕实际瓷砖的角落并正确添加边框？

<DataTemplate x:Key="SoundTileDataTemplate">
            <StackPanel>

                <Grid Background="{StaticResource PhoneAccentBrush}" 
                    Margin="0,5,6,0" Height="56" Width="400" 


                    toolkit:TiltEffect.IsTiltEnabled="True">
                    <Border BorderBrush="white" BorderThickness="3" CornerRadius="15,15,15,15" />
                    <TextBlock Text="{Binding Title}" FontSize="19" TextWrapping="Wrap" Width="140" FontFamily="Tahoma" />
                    <Image Source="/Assets/tiles/soundwave1.png" Width="30" VerticalAlignment="Bottom" HorizontalAlignment="Right" Margin="0,0,6,6" Visibility="{Binding Status, Converter={StaticResource DownloadStatusToIconVisibilityConverter}}" />
                    <ProgressBar Height="12" VerticalAlignment="Bottom" Padding="0" Margin="0" Foreground="{StaticResource PhoneForegroundBrush}" Value="{Binding DownloadProgress}" Visibility="{Binding Status, Converter={StaticResource DownloadStatusToProgressBarVisibilityConverter}}"/>
                </Grid>
            </StackPanel>
        </DataTemplate>

您的网格正在设置背景颜色，但形状不像边框。删除它。

<Grid Background="{StaticResource PhoneAccentBrush}"

设置边框背景颜色。

<Border BorderBrush="white"
                    BorderThickness="3"
                    CornerRadius="15,15,15,15"
                    Background="{StaticResource PhoneAccentBrush}"></Border>
