Databinding to checkbox in wpf

I have a WPF window with a few checkboxes. I want to bind these checkboxes to boolean properties in my object, so changes in data will be reflected in view, and changes in view will be reflected in data. Do I have to derive this object from INotifyPropertyChanged?

As the documentation suggestes, you will have to do so. You must provide properties and inside those properties fire the PropertyChangedEvent. Here is an example from the documentation:

public string PhoneNumber
    {
        get
        {
            return this.phoneNumberValue;
        }

        set
        {
            if (value != this.phoneNumberValue)
            {
                this.phoneNumberValue = value;
                NotifyPropertyChanged();
            }
        }
    }

You will need to make this fit to your needs, though. Please have a look at MSDN on how to implement the interface properly.

Yes, otherwise when you change values in your object, the checkboxes' bindings won't update properly.
