tabcycling is not working after datagridinsertin

Question

question:

tabcycling is not working after datagridinsertin()

the processflow is following:

select guestdetails-->Employee details-->Details to grid-->Advance-->Discount.

tab cycling is moving nicely by default. but if we cycle the tab after gridinsertion it stay on hours textbox(data for datagridinsert)

code :

private void txtnoofPer_KeyUp(object sender, KeyEventArgs e)

{

try

{

if (e.KeyCode == Keys.Enter)

{

ConfCheckinDetailsToGrid();

}

}

catch (Exception ex) { }

}

--------------------------

public void ConfCheckinDetailsToGrid()

{

if (txtTotalHours.Text != "0")

{

string roomID = Convert.ToString(cmbroomno.SelectedValue);

object[,] ParamArray = new object[,] { { "@RoomID", roomID } };

DataSet ds = new DataSet();

ds = DB.ExecuteQuery_SP("SelectRoomDetailsForGridByID", ParamArray);

if (ds.Tables.Count > 0)

{

int row = 0;

row = dgvcheckin1.FirstFreeRow;

//dgvcheckin1.DataSource = null;

dgvcheckin1.Rows.Add();

row = dgvcheckin1.Rows.Count - 1;

dgvcheckin1.Rows[row].Cells["RoomNo"].Value = ds.Tables[0].Rows[0]["RoomNo"].ToString();

dgvcheckin1["RoomNo", row].Value = ds.Tables[0].Rows[0]["RoomNo"].ToString();

dgvcheckin1["RoomCategoryName", row].Value = ds.Tables[0].Rows[0]["RoomCategoryName"].ToString();

dgvcheckin1["RoomCapacity", row].Value = ds.Tables[0].Rows[0]["RoomCapacity"].ToString();

dgvcheckin1["NoofPerson", row].Value = txtTotalHours.Text;

dgvcheckin1["Hours", row].Value = txtTotalHours.Text;

dgvcheckin1["InTime", row].Value = dtpchkintime.Text;

dgvcheckin1["CheckInDate", row].Value = dtpcheckin.Text;

dgvcheckin1["Rents", row].Value = ds.Tables[0].Rows[0]["PerdayRent"].ToString();

dgvcheckin1["TaxAmount", row].Value = ds.Tables[0].Rows[0]["TaxAmount"].ToString();

dgvcheckin1["CheckOutday", row].Value = dtpcheckOutdate.Text;

dgvcheckin1["CheckOutTime", row].Value = dtpouttime.Text;

dgvcheckin1["Roomid", row].Value = cmbroomno.SelectedValue;

if (Convert.ToInt32(txtTotalHours.Text) > 1)

{

double NetTotal = ((Convert.ToDouble(ds.Tables[0].Rows[0]["PerdayRent"]) + Convert.ToDouble(ds.Tables[0].Rows[0]["TaxAmount"])) + ((PolosysHMS.General.Classes.Settings.InventorySettings.ExtraHoursCost) * (Convert.ToDouble(txtTotalHours.Text) - 1)));

dgvcheckin1.Rows[row].Cells["NetTotal"].Value = NetTotal.ToString();

}

//dgvcheckin["RoomId",row].Value = ds.Tables[0].Rows[0]["RoomID"].ToString();

RoomCap = Convert.ToInt32(dgvcheckin1.Rows[row].Cells["RoomCapacity"].Value);

rent = Convert.ToDouble(dgvcheckin1.Rows[row].Cells["Rents"].Value.ToString());

tax = Convert.ToDouble(dgvcheckin1.Rows[row].Cells["TaxAmount"].Value.ToString());

No_Of_Hours = Convert.ToInt32(dgvcheckin1.Rows[row].Cells["Hours"].Value);

//if (txtnoofPer.Text == "")

//{

// txtnoofPer.Text = "0";

//}

No_of_Person = Convert.ToInt32(dgvcheckin1.Rows[row].Cells["NoofPerson"].Value);

//if (No_of_Person > RoomCap)

//{

// Ext_Person = No_of_Person - RoomCap;

// add_amt_forRoom = Ext_Person * 50;

// txttotal.Text = Convert.ToString((rent + tax + add_amt_forRoom) * No_Of_days);

// total += Convert.ToDouble(txttotal.Text);

// txttotal.Text = Convert.ToString(total);

// txtbalance.Text = Convert.ToString(total);

//}

//else

//{

double NetTotalCal = Convert.ToDouble(dgvcheckin1.Rows[row].Cells["NetTotal"].Value);

double totatl = +NetTotalCal;

txttotal.Text = totatl.ToString();

//txttotal.Text = Convert.ToString((rent + tax) * No_Of_Hours);

// total += Convert.ToDouble(txttotal.Text);

// txttotal.Text = Convert.ToString(total);

txtbalance.Text = Convert.ToString(totatl);

txtBillingAmount.Text = Convert.ToString(totatl);

Bal(txtbalance, txttotal, txtadvance, txtDiscount);

}

}

//int Roomno_Bookingprocess = Convert.ToInt32(cmbroomno);

//objGeneralclass.UpdateOnBookingProcess(Convert.ToInt32(cmbroomno.SelectedValue), true);

ClearInputGridField();

}

-------------------------------------------

tested solution :

1. I checked any focus on hourstextbox.

2. test with out updateBookingprocess()function

3. test with out ClearInputGridfield()
