custom DataGridViewComboBoxCell with floating label on it

Hi, I want to have two controls in the same datagridview column.

I want to customize the DataGridViewComboBoxCell so that it will show the values of the selected value and on it a floating label with some text. in the past i was able to do it with a checkbox and a label but the problem with the DataGridViewComboBoxCell is that it comes out with an empty datasource when I override the paint event.

I tried to assign the datasource again after I used the Paint event but then although I see values in the DataGridViewComboBoxCell and the label showing the right value, I get into an infinite loop so I see the GUI blinking constantly.

10x for the help.

the code is the following:

*when the form loads

MyDGVCheckBoxColumn col = new MyDGVCheckBoxColumn();
            col.DataPropertyName = "value";
            col.DataSource = list;
            col.DisplayMember = "Yes";
            col.ValueMember = "value";
            col.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;
            this.dataGridView1.Columns.Add(col);
            this.dataGridView1.RowCount = 50;

the class for the generic list:

    public class CheckThis
    {
        public string Yes { get; set; }
        public string value { get; set; }

        public CheckThis()
        {
            Yes = "gggg";
            value = "1";
        }
    }

the code for the custom DataGridViewComboBoxCell (I used a similar example in the past from some site)

 public class MyDGVCheckBoxColumn : DataGridViewComboBoxColumn
    {
        private string label;

        public string Label
        {
            get
            {
                return label;
            }
            set
            {
                label = value;
            }
        }

        public override DataGridViewCell CellTemplate
        {
            get
            {
                return new MyDGVCheckBoxCell();
            }
        }
    }

    public class MyDGVCheckBoxCell : DataGridViewComboBoxCell
    {
        private string label;

        public string Label
        {
            get
            {
                return label;
            }
            set
            {
                label = value;
            }

        }

        protected override void Paint(Graphics graphics, Rectangle clipBounds, Rectangle cellBounds, int rowIndex, DataGridViewElementStates elementState, object value, object formattedValue, string errorText, DataGridViewCellStyle cellStyle, DataGridViewAdvancedBorderStyle advancedBorderStyle, DataGridViewPaintParts paintParts)
        {

            // the base Paint implementation paints the check box
            base.Paint(graphics, clipBounds, cellBounds, rowIndex, elementState, value, formattedValue, errorText, cellStyle, advancedBorderStyle, paintParts);

            // Get the check box bounds: they are the content bounds
            Rectangle contentBounds = this.GetContentBounds(rowIndex);

            // Compute the location where we want to paint the string.
            Point stringLocation = new Point();
            stringLocation.Y = cellBounds.Y + 30;

            stringLocation.X = cellBounds.X + contentBounds.Bottom;


            // Paint the string.
            var res = false;
            MyDGVCheckBoxColumn col = (MyDGVCheckBoxColumn)this.OwningColumn;
            col.DataSource = list;
            col.DisplayMember = "Yes";
            col.ValueMember = "value";


                    this.label = "Customer Does Not Appear";


            graphics.DrawString(
            this.Label, new Font("Arial", 6, FontStyle.Bold), System.Drawing.Brushes.Red, stringLocation);

        }


        public object list { get; set; }
    }
