xamarin.forms - Xamarin 表单 SfDataGrid 自定义映射

Question

我正在使用带有同步融合的 xamarin 表单开发应用程序。我无法为下面的 json 文件创建解决方案。

该页面由 3 列组成，并从标签字段中获取这些列标题。（这对所有属性都是一样的）

它从显示区域获取内容。

我不能在这里进行法线映射。需要不同的视角。

如果你能帮助我，我会很高兴。谢谢你。

我们想说，这不是用 SfDataGrid 填充 JSON 数据的正确方法。由于您已经为所有三个属性初始化了 Value 。因此，文本取自“值”字段。我们已经发布了一个 KB 来使用 SfDataGrid 填充 JSON 数据。
