I have an issue which only occurs when the view is not maximized, set property generates the above error
<telerik:RadGridView helpers:GridViewColumnHelper.HideNonImportantColumns="{Binding IsInOverviewState}"

public ContactsViewState State
    {
        get
        {
            return _state;
        }
        set
        {
            SetProperty(ref _state, value);
            OnPropertyChanged(() => IsInOverviewState);
        }
    }
Thanks for any help in advance
