Change highlight color of NSTableView selected row

Question

how to change NSTable selected row background color?

here is good answer, but it is for uitable view .

For now,what I see is that I can change selected hilight style :

MyTAble.SelectionHighlightStyle = NSTableViewSelectionHighlightStyle.Regular;

But here is only 3 options;

None = -1L,
        Regular,
        SourceList

I have tried following solution :

patientListDelegate.SelectionChanged += (o, e) => {
                        var r = PatientTableView.SelectedRow;
                        var v = PatientTableView.GetRowView (r, false);
                        v.Emphasized = false;
                    };

It works normally , but if I minimize and then open application again , still shows blue color

I found answer in objective-c

Change selection color on view-based NSTableView

Here is c# implementation:

inside delegate :

public override NSTableRowView CoreGetRowView (NSTableView tableView, nint row)
        {
            var rowView = tableView.MakeView ("row", this);
            if (rowView == null) {
                rowView = new PatientTableRow ();
                rowView.Identifier = "row";
            }
            return rowView as NSTableRowView;
        }

and custom row :

public class PatientTableRow : NSTableRowView
    {
        public override void DrawSelection (CGRect dirtyRect)
        {
            if (SelectionHighlightStyle != NSTableViewSelectionHighlightStyle.None) {

                NSColor.FromCalibratedWhite (0.65f, 1.0f).SetStroke ();
                NSColor.FromCalibratedWhite (0.82f, 1.0f).SetFill ();

                var selectionPath = NSBezierPath.FromRoundedRect (dirtyRect, 0, 0);

                selectionPath.Fill ();
                selectionPath.Stroke ();
            }
        }
    }
