   {           GridViewRow currentRow =(GridViewRow)((TextBox)sender).Parent.Parent;

     TextBox txt = (TextBox)currentRow.FindControl("txtCode");

     TextBox txtfine = (TextBox)currentRow.FindControl("txtFine");

         Int32 count =Convert.ToInt32( txt.Text);

     var chkradio = rblQualification.SelectedValue;

       byte chkRadio = SafeConvert.ToByte(chkradio);

     var vehiclecategory = _service.GetAllVehicleCategory().Where(x => x.ID == chkRadio).FirstOrDefault();

            var vehicletype = vehiclecategory.VehicleType_Id;

              var pntytype = _service.GetAllVehiclePenaltyType().Where(x => x.ID == SafeConvert.ToByte(count)).Count();

            var plntyfee = _service.GetAllVehiclePenaltiesFee().Where(x => x.VehicleTypeID == vehicletype && x.VehiclePenaltyTypeID == vehicletype).FirstOrDefault();             txtfine.Text = plntyfee.Fee.ToString();          }

Make sure that you are getting proper value in plntyfee.Fee Debug it and see what is the value you are getting. If Fee is blank value how it will display in textbox.

txtfine.Text = plntyfee.Fee.ToString();

TextBox txt = (TextBox)currentRow.FindControl("txtCode");
