 <p>A couple suggestions:</p> <p>1 ) Instead of this: </p> <p>Command="{Binding ViewModel.GetQuoteQuestionsCommand, Mode=OneWay}" /></p> <p>try: Command="{Binding ViewModel.GetQuoteQuestionsCommand}" /></p> <p>2) Don't "roll your own" RelayCommand. Use an MVVM library such as MvvmLight and use the RelayCommand provided there. </p>
