Autonumber column in GridView

I have a simple gridview that displays a "Top 10" list. The list is ordered by a Rank column in the db, but this column doesn't necessarily have 1-10 listings. it might go 245, 256, 280, 290.. etc.

Is there a easy, easy, simple way to have a template field that just does a 1 to 10 autonumber type thing? This was easy as pie in ASP.Classic, a little looped number generation, but in C# and .Net 2.0, I'm hitting a roadblock.

when you fill the dataset/datatable from db ordered by rank in the select use top 10 statement
Example: SELECT TOP 10 column1, column2 from mydb order by RANK ASC

this will get the first 10 listings and you don't have to modify anything in gridview

As I understand your question you want to display the 1-10 number listings in the grid. Fool about with the following code that applies the current row number to the rowheadercell (the grey leftmost item in the grid).

public static void applyRowNumbersToGrid(DataGridView grid)
{
      int rowNumber = 1;
      grid.RowHeadersVisible = true;
      grid.RowHeadersWidthSizeMode = DataGridViewRowHeadersWidthSizeMode.AutoSizeToAllHeaders;
      foreach (DataGridViewRow row in grid.Rows) {
        if (row.IsNewRow) continue;
        row.HeaderCell.Value = Convert.ToString(rowNumber);
        rowNumber++;
      }
}
