推荐答案

您需要将usercontrol中的事件冒泡到主窗口。一旦事件被路由，你可以在主窗口中捕获事件，它将像你所描述的那样工作



在上面我的DataGrid直接托管在TabItem 4不是UserControl，我能够导航TabItem 1



希望你能得到这个想法。希望它有所帮助：）

You need to bubble event in usercontrol to the main window. once the event is routed you can catch the event in mainwindow and it will work like the one what you have described

"Before above when my DataGrid is directly hosted on the TabItem 4 not a UserControl, I am able to navigate the TabItem 1 "

Hope you are getting the idea. Hope it helps :)
