  Hallo,
  we have a new issue with RadTabControl - when we use style selector to use RadTabControl in MVVM concept, after we create more than one TabItems, after each active tab control item change, the View's constructor is everytime called.. - why RadTabControl is creating everytime new instance??? (-> Click on the button to add any tab items, create breakpoint into constructor UserControl1() and switch between the tabs...)
  When we change RadTabControl into TabControl (remove all Telerik's stuff from MainWindow.xaml), the problem is solved... Thank you for your help...

  Hi Tomas ,

   In order to keep the TabItem's content in memory (and this way not re-initializing) you can set the IsContentPreserved to True. Please check out this help article for more info on this.
  On a side note, you will be able to attach zips if you open a support thread.
