The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

DataGridView containing DataGridViewComboBoxColumn VS 2008 C# Windows App

Zones: Windows Forms for .Net, C# Programming Language

Tags: ASP.NET 2008 DataGridView DataGridViewComboBoxColumn, C# Windows App Framework 3.5

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);
