How to add the values stored in the dataset....

How to add the values stored in the dataset....

I am having a dataset which stores the values retrived from a table.
Here is the code for taht,

SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["sqlconnectionstring"].ConnectionString);
SqlCommand command = new SqlCommand("dbo.Utlisation_tab", conn);
command.CommandType = CommandType.StoredProcedure;
conn.Open();
SqlDataAdapter adapter = new SqlDataAdapter(command);
DataSet ds = new DataSet();
adapter.Fill(ds, "dbo.Utlisation_tab");
conn.Close();

From this dataset, i am put the values to a gridview using Datatable...

foreach (DataRow dr in ds.Tables[0].Rows)
{
newRow = tempTable.NewRow();
newRow["col1"] = dr.ItemArray[11].ToString();
newRow["col2"] = dr.ItemArray[0].ToString();
newRow["col3"] = dr.ItemArray[1].ToString();
newRow["col4"] = dr.ItemArray[2].ToString();
newRow["col5"] = dr.ItemArray[3].ToString();
newRow["col6"] = dr.ItemArray[4].ToString();
newRow["col7"] = dr.ItemArray[5].ToString();
newRow["col8"] = dr.ItemArray[6].ToString();
newRow["col9"] = dr.ItemArray[7].ToString();
newRow["col10"] = dr.ItemArray[8].ToString();
newRow["col11"] = dr.ItemArray[9].ToString();
newRow["col12"] = dr.ItemArray[10].ToString();
newRow["col13"] = dr.ItemArray[12].ToString();
//newRow["col14"] = tempTable.Compute("SUM(dr.ItemArray)","").ToString();
//String sum = tempTable.Compute("Sum ( [col1] ) ", "").ToString();

RowsDS.Tables[0].Rows.Add(newRow);
}

In the above code, col14 is for dispalying total.
So how can a add the values and display it in col14.

Hi,
Why don't you sort in SQL Query Level? Its best and good in performance also. I strongly recommend in SQL Query level.

Thanks,
Amit
