I have a frame which displays certain websites. All allowed websites are saved in a sql Db. I am using entity framework to link to the DB. I want to block the user from accessing external links but allow them to navigate within the allowed websites.

I''m completely stumped :~, I don''t know where to start :confused:. Any help would be greatly appreciated.

推荐答案

处理Frame.Navigating事件，并为要阻止的 URI 将NavigatingCancelEventArgs.Cancel 设置为true .

Handle the Frame.Navigating event and set NavigatingCancelEventArgs.Cancel to true for URIs you want to block.
