WinForms data binding to a custom property throws an exception

I am sorry if this is a duplicate, but I searched the net and haven't found an answer

I am trying to bind the control's Enabled (or ReadOnly for TextBox):

this.tbProj.DataBindings.Add(new Binding("Enabled", this, "CanEdit", false, DataSourceUpdateMode.OnPropertyChanged, false));
this.btnSave.DataBindings.Add(new Binding("Enabled", this, "Dirty", false, DataSourceUpdateMode.OnPropertyChanged, false));

To the following properties:

public bool Dirty { get; set; }

private bool CanEdit
{
    get { return this._CurrentRecord.CanEdit(); }
}

I get System.ArgumentException: Cannot bind to the property or column CanEdit on the DataSource. when trying to ShowDialog() the form.

If I bind the Enabled or ReadOnly to Dirty, everything forks fine. I tried get { return true; } and even added a setter: set { bool bummy=value; }, same error. I even changed CanEdit to an auto-implemented property, same as Dirty (just get; set; in declaration) at no avail...

Please help.

Thanks for any hints and advice.

The property has to be public:

public bool CanEdit
{
    get { return this._CurrentRecord.CanEdit(); }
}
