if I want to clear selected item in the viewmodel and raise like below. it will throw this exception. why should this behave like that? how can you clear the selected item using mvvm binding?
SelectedItem = null;
RaisePropertyChanged("SelectedItem");
<sfListView:SfListView x:Name="list"
ItemsSource="{Binding Items}" SelectedItem="{Binding SelectedItem, Mode=TwoWay}"
