C# Calendar Control Checkboxes in Date Cells

Hi --

I have a (c# 2.0) calendar control that loads a menu of lunch choices for each day inside the cell corresponding to that day in the dayrender event. That is all working great. I have no idea how to get the checked value of  any of the boxes, though! I've tried to loop through the controls to see if any are checkboxes, but I can't seem to get "inside" the calendar itself.

Any ideas or guidance would be appreciated.

Code for the dayrender:

protected void LunchCalendar_DayRender(object sender, DayRenderEventArgs e)
    {
        {
            //if (e.Day.IsWeekend)
            //{ 
            //    e.Cell.Visible = false;
            //}

            DateTime daDate = DateTime.Parse(e.Day.Date.ToString());

            if (!e.Day.IsOtherMonth && !e.Day.IsWeekend)
            {
                // Set the width as it will have data
                e.Cell.Width = 140;

                // DataRow[] rowTest = dtService.Select(string.Format("[ServiceDate] = '{0}'", e.Day.Date));
                DataRow[] rowsExisting = dtExisting.Select("LunchDate = '" + daDate + "'");
                DataRow[] rowsService = dtService.Select("ServiceDate = '" + daDate + "'", "CategoryName ASC, ProductName DESC");

                if (rowsExisting.Length == 0 && rowsService.Length == 0)
                {
                    e.Cell.Controls.Add(new LiteralControl("&lt;br /><br />"));
                    e.Cell.Controls.Add(new LiteralControl("&lt;br /><br /><center>"));
                    Label labelNone = new Label();
                    labelNone.ForeColor = System.Drawing.Color.Black;
                    labelNone.Font.Name = "Verdana";
                    labelNone.Font.Size = FontUnit.Point(10);
                    labelNone.Font.Bold = true;
                    labelNone.Text = "No Lunches Available";
                    e.Cell.Controls.Add(labelNone);
                    e.Cell.Controls.Add(new LiteralControl("&lt;/center>"));
                }

                // Create a label to print ordered info of each returned row.
                for (int i = 0; i < rowsExisting.Length; i++)
                {
                    Label label = new Label();
                    label.Text = rowsExisting[i][0].ToString() + " ea. " + rowsExisting[i][3].ToString();
                    e.Cell.Controls.Add(label);
                    e.Cell.Controls.Add(new LiteralControl("&lt;br />"));
                }

                // Create a check box control to use for ordering of each returned row.
                if (rowsService.Length > 0)
                {
                    string category = "";
                    // add a break to get the values down from the number
                    e.Cell.Controls.Add(new LiteralControl("&lt;br /><br />"));

                    for (int i = 0; i < rowsService.Length; i++)
                    {
                        // Get the value of the new category
                        string newCategory = rowsService[i][0].ToString();

                        if (category == newCategory)
                        {
                            // nada
                        }
                        else
                        {
                            e.Cell.Controls.Add(new LiteralControl("&lt;br />"));
                            Label labelCategory = new Label();
                            labelCategory.Text = newCategory;
                            labelCategory.Font.Name = "Verdana";
                            labelCategory.Font.Size = 9;
                            labelCategory.Font.Bold = false;
                            labelCategory.Width = 120;
                            labelCategory.Height = 15;
                            labelCategory.BackColor = System.Drawing.Color.LightSkyBlue;
                            e.Cell.Controls.Add(labelCategory);
                            e.Cell.Controls.Add(new LiteralControl("&lt;br />"));
                        }

                        // add a checkbox with the appropriate values...
                        CheckBox checkbox = new CheckBox();
                        checkbox.ID = rowsService[i][2].ToString() + "_" + rowsService[i][3].ToString();
                        checkbox.Text = "";
                        HyperLink hyperlink = new HyperLink();
                        hyperlink.Text = rowsService[i][1].ToString() + " @ " + String.Format("{0:c}", rowsService[i][5]);
                        hyperlink.NavigateUrl = "~/ProductDetails.aspx?ProductID="+rowsService[i][2].ToString();
                        e.Cell.Controls.Add(checkbox);
                        e.Cell.Controls.Add(hyperlink);
                        e.Cell.Controls.Add(new LiteralControl("&lt;br />"));
                        // reset the category value
                        category = newCategory;

                    }

                }

                e.Cell.BackColor = System.Drawing.Color.LightGoldenrodYellow;
            }
            else
            {
                e.Cell.Width = 25;
            }
        }
    }

Thanks for your help.
