I have wpf applicaton based on MVVM pattern. I have annoying issue and I can`t figure how can I solve it.

My application is wizard application, When the user press "Next" I am starting some progress in another thread (backgroundworker), when the bgWorker is starting he set CanMoveNext = false which binded to Next button isEnabled property and when the bgworker is finish he set back CanMoveNext = true;

When CanMoveNext get IsEnabled = false the UI show it immediately but after the isEnabled propery set back to true the UI do the refresh just after a mouse click or keyboard key press.

After I m changing the property I m using OnPropertyChanged() method, I even tried use CommandManager.InvalidateRequerySuggested(); but it`s still not get refreshed without mouseclick.

How can I solve this problem?

Here is my code:

       public override bool CanMoveNext
                return canMoveNext;
                canMoveNext = value;
                OnPropertyChanged("CanMoveNext");
    public void StartProgress()
                CanMoveNext = false;
                InitBGworkers(out bgStartPersonalWorker);
    bgStartPersonalWorker.RunWorkerAsync();
        void bgStartPersonalWorker_DoWork(object sender, DoWorkEventArgs e)
            DoStuff();
        void bgStartPersonalWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
     CanMoveNext = true;
//Even  CommandManager.InvalidateRequerySuggested(); doen`t help
//Code from XAML
<Button Content="{Binding ButtonNextCaption}" IsEnabled="{Binding CanMoveNext, UpdateSourceTrigger=PropertyChanged}" Command="{Binding Path=NavigateNextCommand}" Margin="5,0,5,0" Width="100" Height="40" FontSize="14" FontWeight="Bold"/>
Thanks
                Just a wild shot, but have you tried setting the property from the UI thread? e.g. Setting the CanMoveNext using a Dispatcher.Invoke?

            Application.Current.Dispatcher.BeginInvoke(new ThreadStart(() =>
                CommandManager.InvalidateRequerySuggested();
                Using method group: Application.Current.Dispatcher.BeginInvoke(new ThreadStart(CommandManager.InvalidateRequerySuggested));
