WPF TabItem Content alignment is always centered

阅读更多关于 WPF TabItem Content alignment is always centered

问题 I'm trying to put some content inside my TabItem, but I can't add a container that fills the space of the TabItem. Anything that I add shows up centered. I'm using a Theme from WPF Toolkit ( WhistlerBlue.xaml ), so I think that maybe it's that what is causing me this issue. I cannot remove the Theme, because I need it.

阅读更多关于 How can I switch tabs programatically from within my ViewModel?

问题 I have a MVVM desktop application. In my View, I have a TabControl . Any suggestions on the best practice to switch to a specific tab by changing a property on the ViewModel?
