问题描述
我的应用程序显示数据库中DataGrid 的fetures 权限.为了实现这一点，我使用了 MyToolkit.Controls.DataGrid.现在我想要输出，如果用户选中管理员或更新/删除/创建复选框，然后查看和列表复选框选中反之亦然，并且我还想从数据库中设置复选框选中的值.提前致谢.
My application displays the fetures permissions on DataGrid from database. For realizing this I am using the MyToolkit.Controls.DataGrid. Now i want output for if user checked the admin or update/delete/create check box then View and list check box checked vice versa same for the and also i want to set checkbox checked value from database.
thanks in advance.

如果用户选中了创建/更新/删除，则应选中相同的行列表和视图
if user checked the create/update/delete then same row list and view should be checkbox checked
如果用户选中了视图复选框，则应选中选定的行列列表
if user checked the view check box then selected row column list should be checked

推荐答案
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.
in simple way if user click on update/create/delete check boxes then list and view check box row should be checked AND if user checked the view checkbox then List checkbox should be checked.
根据您的需求，您可以使用两种方式绑定来实现.详细代码请参考以下.以下代码是根据你提供的demo修改的，可以直接复制替换.
For your requirement, you could use two way bind to realize. For details code please refer the following. The following code was modified base on your provided demo, you could copy and replace directly.
