XAML can't use constructor with parameter. Keep what you've tried with dependency property :

then you can try this in constructor :

public Myusercontrol()
{
    InitializeComponent();
    Loaded += (sender, args) =>
          {
                UserControlViewModel vm = new UserControlViewModel(Param1);
                this.DataContext = vm;
          };
}
