DataGridView containing DataGridViewComboBoxColumn VS 2008 C# Windows App

I am attempting to add a DataGridViewComboBoxColumn to an existing DataGridView control. I am having difficulty populating the combobox with dropdown values, and I am not able to view them when I select the combobox dropdown when the grid has finished loading. I have searched for a small working example where combobox values are being added programatically but have had no luck. Could someone explain why the dropdown values are not populating or are not viewable in the dropdown list?
Thanks!

I have included my test code:
DataTable dtBook = new DataTable();
//Create Columns in DataGridView
dtBook.Columns.Add("bookid", typeof(int));
dtBook.Columns.Add("bookname", typeof(string));
dtBook.Columns.Add("startTime", typeof(DateTime));
dtBook.Columns.Add("endTime", typeof(DateTime));
//Create Rows in DataGridView
for (int i = 0; i < 10; i++)
{
   DataRow dr = dtBook.NewRow();
   dr[0] = i;
   dr[1] = "book" + i.ToString();
   dr[2] = new DateTime(2007, 1, 1);
   dr[3] = DateTime.Now;
   dtBook.Rows.Add(dr);
}
//Add Rows to DataGridView
dataGridView1.DataSource = dtBook;
//Create DataGridView ComboBox Column
DataGridViewComboBoxColumn colStatus = new DataGridViewComboBoxColumn();
colStatus.AutoSizeMode = DataGridViewAutoSizeColumnMode.ColumnHeader;
 
//Specify the list of choices in the combo box
colStatus.Items.AddRange("New", "Used");
//Sort the combo box contents alphabetically
colStatus.Sorted = true;
//Disable sorting for the column
colStatus.SortMode = DataGridViewColumnSortMode.NotSortable;
colStatus.HeaderText = "Condition";
colStatus.Name = "Condition";
colStatus.ReadOnly = false;
dataGridView1.Columns.Add(colStatus);

My previous grid had read only set to true AND the Selection Mode was set to Full Row Select. I caught the Selection Mode issue but I don't think I would have even looked at the Read Only property for the grid until I eventually dropped a new DataGridView control and sorted through the differences. Hope this might help those like myself in the future! =]
