To fix the issue you can do I have a ListView and since it supports multiple selection I have a button where I gather all the SelectedItems and pass them using CommandParameter. Being very new to this I really don't know how to do so with parameters. How do I access the list when it has been passed to my ViewModel? Please see below code: , ListView.SelectedItems is an IList:
code :
private ICommand _selectBtnOnClickCommand;
public ICommand SelectBtnOnClickCommand
        if (_selectBtnOnClickCommand == null)
            _selectBtnOnClickCommand = new RelayCommand(o =>
                var selectedSites = (o as IList);
                if (selectedSites != null)
                    foreach (var model in selectedSites.OfType<SiteUrlsModel>())
        return _selectBtnOnClickCommand;

it helps some times The problem is that, like the Popup control, it's a different visual tree. The error is telling you that it is trying to find a property called 'CommandParameter' on a 'RadMenuItem', because this is the DataContext it has within the ContextMenu's visual tree.
