Hi,
Use your datasource to find the solution. Try this:

C#

DataTable tblTest= new DataTable();
tblTest.Columns.Add("ProductName", typeof(string));
tblTest.Columns.Add("Price ", typeof(double));

//insert your data
tblTest.Rows.Add("Pen", 10.00);
tblTest.Rows.Add("Paper", 12.00);
tblTest.Rows.Add("Pen", 10.00);
tblTest.Rows.Add("ColorBrush", 5.00);
// query with LINQ 
var query = from row in tblTest.AsEnumerable()
            group row by row.Field<string>("ProductName") into Products
            orderby Products.Key
            select new
            {
                ProductName = Products.Key,
                ProductCount = Products.Count()
            };

Hereafter you can print your records

C#

foreach (var Prod in query)
{
    Console.WriteLine("{0}\t{1}", Prod.ProductName, Prod.ProductCount);
}

Your output will be like:

C#

Pen           2
Paper         1
ColorBrush    1

C#

List<string> rows = new List<string>();

foreach (DataGridViewRow row in this.GridView.Rows)
{
    if (rows.Contains(row.Cells["ProductName"].Value.ToString()))
         continue;

    rows.Add(row.Cells["ProductName"].Value.ToString())

    // if you need just count so rows.Count is your answer
}
