回答1:

in simple way if user click on update/create/delete check boxes then list and view check box row should be checked AND if user checked the view checkbox then List checkbox should be checked.

For your requirement, you could use two way bind to realize. For details code please refer the following. The following code was modified base on your provided demo, you could copy and replace directly.

FeatureData class

public class FeatureData : INotifyPropertyChanged
{
    public int featureId { get; set; }
    public string featureName { get; set; }

    private bool _create;

    public bool Create
    {
        get { return _create; }
        set
        {
            _create = value;
            UpdateViewAndList(value);
            OnChanged();
        }
    }
    private bool _update;

    public bool Update
    {
        get { return _update; }
        set
        {
            _update = value;
            UpdateViewAndList(value);
            OnChanged();
        }
    }
    private bool _delete;

    public bool Delete
    {
        get { return _delete; }
        set
        {
            _delete = value;
            UpdateViewAndList(value);
            OnChanged();
        }
    }
    private bool _list;
    public bool List
    {
        get { return _list; }
        set
        {
            _list = value;
            OnChanged();
        }
    }
    private bool _view;
    public bool View
    {
        get { return _view; }
        set
        {
            _view = value;
            this.List = value;
            OnChanged();
        }
    }
    private void UpdateViewAndList(bool value)
    {
        if (value)
        {
            this.View = true;
            this.List = true;

        }
        else
        {
            this.View = false;
            this.List = false;
        }
    }
    //public string index { get; set; }
    public FeatureData(bool Create, bool Update, bool Delete, bool List, bool View, int featureId, string featureName)
    {
        this.featureId = featureId;
        this.featureName = featureName;
        this.Create = Create;
        this.Update = Update;
        this.Delete = Delete;
        this.List = List;
        this.View = View;
        //this.index = index;
    }

    private bool _IsSelected = false;
    public bool IsSelected { get { return _IsSelected; } set { _IsSelected = value; OnChanged("IsSelected"); } }

    #region INotifyPropertyChanged Members

    public event PropertyChangedEventHandler PropertyChanged;
    private void OnChanged([CallerMemberName]string prop = null)
    {
        if (PropertyChanged != null)
            PropertyChanged(this, new PropertyChangedEventArgs(prop));
    }

    #endregion
