when i filter my grid with Status im getting records 

 

and im looping through the grid to get each row values storing in a string variable and send to database
im trying like this
 

protected void HitAPI_Click(object sender, EventArgs e)
        {
            foreach(GridViewRow gridViewRow in Paymentview.Rows)
            {
                for (int i = 0; i < Paymentview.Columns.Count; i++)
                {
                    if (!String.IsNullOrWhiteSpace(gridViewRow.Cells[2].Text))
                    {
                        String RequestID = gridViewRow.Cells[2].Text;

                    }
                    if (!String.IsNullOrWhiteSpace(gridViewRow.Cells[3].Text) || gridViewRow.Cells[3].Text== "&nbsp;")
                    {
                        String AckNo = gridViewRow.Cells[3].Text;
                    }
                    if (!String.IsNullOrWhiteSpace(gridViewRow.Cells[4].Text))
                    {
                        String UTR = gridViewRow.Cells[4].Text;
                    }
                    string statusValue = DataBinder.Eval(e.gridViewRow.DataItem, "Status").ToString();
                }
            }
        }
