win-universal-app - Xamarin Form - 如何在 UWP 中选中另一个复选框上的复选框
问题描述
我的应用程序显示DataGrid来自数据库的功能权限。为了实现这一点，我正在使用MyToolkit.Controls.DataGrid. 现在我想要输出是否用户检查了管理员或更新/删除/创建复选框，然后查看和列表复选框检查反之亦然，并且我想从数据库中设置复选框检查值。提前致谢。

如果用户检查了创建/更新/删除，则应选中相同的行列表和视图
如果用户选中视图复选框，则应选中选定的行列列表

解决方案
以简单的方式，如果用户单击更新/创建/删除复选框，则应选中列表和查看复选框行，如果用户选中查看复选框，则应选中列表复选框。
根据您的要求，您可以使用两种方式绑定来实现。详细代码请参考以下。以下代码是根据您提供的演示修改的，您可以直接复制和替换。
