WPF 中 Fluent Ribbon 按钮控件上的图标徽章

Question

我是 WPF 新手，想在按钮图片的右上角显示徽章。按钮显示在 Fluent 功能区上。我在这里看到 nir 的答案，看起来不错，但我不知道如何将其应用于按钮控制。

这是我要应用徽章的按钮控件。

  <Fluent:RibbonGroupBox Fluent:KeyTip.Keys="C" Header="">
                        <Fluent:Button Fluent:KeyTip.Keys="LC" Header=" Transactions" Name="btnTransactions" MinHeight="67" Icon="Images/transferbig.gif" LargeIcon="Images/transfer.gif" FontWeight="Normal"></Fluent:Button>
                    </Fluent:RibbonGroupBox>

请告知是否有任何其他兼容 windows 7、8 和 10 的方法。

我遇到了这个 https://mahapps.com/controls/badged-control.html 我相信它对任何人开放，但不确定它是否适用于 windows 8.

如果我对你的问题理解正确，你可以将 Label 放在 Button 之上，然后使用 Margin 属性调整其位置，例如：

<Fluent:RibbonGroupBox Fluent:KeyTip.Keys="C" Header="" ClipToBounds="False" Margin="10">
    <Grid>
        <Fluent:Button Fluent:KeyTip.Keys="LC" Header=" Transactions" Name="btnTransactions" MinHeight="67" FontWeight="Normal" />
        <Label Style="{StaticResource CircularLabel}" HorizontalAlignment="Right" VerticalAlignment="Top" Margin="0,-8,-8,0">2000</Label>
    </Grid>
</Fluent:RibbonGroupBox>

这应该会在 Button 的右上角给你一个徽章。
