它是一个在一页中重复使用的按钮。此代码在 application.resources 中。 我将它与静态资源一起使用。 

    <Button Name="BarcodeButton" Content="{StaticResource Icon}"></Button>

当我点击添加按钮时，它会将这个新按钮添加到页面中。我发现的问题是它只显示最新按钮。其他人都消失了。

它工作正常。

最佳答案

这是因为您将内容设置为静态资源。您必须将样式或模板设置为静态资源。

<ControlTemplate x:Key="Icon">
    <Button>
        <Canvas>
            ...
        </Canvas>
    </Button>
</ControlTemplate>

<Button Name="BarcodeButton" Template="{StaticResource Icon}"></Button>
