Hi Praveen TimeSpan sum = TimeSpan.Zero; protected void GridView1_RowDataBound(object sender GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { string times= ((Label)e.Row.FindControl(lbltime)).Text; //string times= e.Row.Cells[columnIndex].Text; sum += (TimeSpan)times ; } if (e.Row.RowType == DataControlRowType.Footer) { Label lbl = (Label)e.Row.FindControl(lblTotal); lbl.Text = sum.ToString(); } } If column is template field then search control else use commented line If the above solution is helpful then accept the answer.

Are u sure u have 7 cells?? Use this GridViewRow row = CustomersGridView.SelectedRow; string s = row.Cells[0].Text;

praveen kumar · Answer

hi Rajeev Punhani getting error on cells[].value 'System.Web.UI.WebControls.TableCell' does not contain a definition for 'Value' and no extension method 'Value' accepting a first argument of type 'System.Web.UI.WebControls.TableCell' could be found (are you missing a using directive or an assembly reference?) Thank you

Rajeev Punhani · Answer

Hi Praveen TimeSpan sum = TimeSpan.Zero; for ( int i = 0; i { sum += (TimeSpan)gridview1.Rows[i].Cells[7].Text; } This you can do in row created or row databound.Change cell index based on time span column. If the above solution is helpful then accept the answer.

Nishant Mittal · Answer

This code is adding one time span in another. TimeSpan.Add returns a new instance of TimeSpan .

praveen kumar · Answer

can you explain me clearly with full code

Nishant Mittal · Answer

Hi Use this totalTime = totalTime.Add(time)//it will return a new timespan
