我正在尝试向网格添加渐变背景和圆角。我有渐变，但我无法让圆角工作。这将是一个状态显示弹出窗口，这就是它背后的想法。还有没有更好的方法来设置渐变？

这将在您的网格周围创建一个具有圆角半径的边框（并使用渐变画笔）：

<Border CornerRadius="3">
    <Border.Background>
        <LinearGradientBrush>
            <!-- Your gradient stops would go here -->
        </LinearGradientBrush>
    </Border.Background>

    <Grid> 
        <!-- Your grid goes here -->
    </Grid>
<Border>
