GridView table headers and iterating over a GridView cells in the row and columns.

Here is a function to get the GridView's table header columns:

   protected string getTableHeaders()
   {
       string retVal = "";
       int TotalColumns = GridView1.Columns.Count;
       int col = 0;
       for (col = 0; col < TotalColumns; col++)
       {
           retVal += GridView1.Columns[col].HeaderText;
           if ((col + 1) < TotalColumns) retVal += ", ";
       }
       return retVal;
   }

Here is how to iterate over the GridView cells to extract row and column data into a string. The cells can be custom delimited. Notice how this does not include Column.HeaderText :

   protected string getDataCells()
   {
       string retVal = "";
       int TotalColumns = GridView1.Columns.Count;
       int TotalRows = GridView1.Rows.Count;
       int col = 0;
       int row = 0;
       if (TotalColumns > 0 && TotalRows > 0)
       {
           for (row =0; row<TotalRows; row++)
           {
               for (col = 0; col < TotalColumns; col++)
               { // uses arbitrary ',' between column cells
                   retVal += GridView1.Rows[row].Cells[col].Text;
                   if ((col + 1) < TotalColumns) retVal += ", ";
               }
               // uses arbitrary ';' for end of row
               retVal += ";";
           }
       }
       return retVal;
   }
