Asp calendar with datasource repeats the label

I have an asp calendar linked to datasource and it fetches the count of number of times a date has repeated in the data table and display it on the calendar. but if there are 2 dates of the same month is on the mysql table then the labels appears twice and thrice if there are 3 dates and so on as shown in the image below.
The code for this is shown below

{

{
cal2.VisibleDate = DateTime.Today;
FillLeaveplannerDataset();
}
}

conn.Close();
if (nextDate == e.Day.Date)
{
e.Cell.BackColor = System.Drawing.Color.Orange;
Environment.NewLine.ToString();
e.Cell.ForeColor = System.Drawing.Color.Red;
e.Cell.Font.Size = 9;
e.Cell.Controls.Add(new LiteralControl("<p></p>Slot available:"));
e.Cell.Controls.Add(new LiteralControl(slot4));
e.Cell.Controls.Add(new LiteralControl("<p></p>Pending:"));
e.Cell.Controls.Add(new LiteralControl(count2));
}
else
{
e.Cell.Font.Size = 9;
e.Cell.Controls.Add(new LiteralControl("<p>Slot available: 10</p>"));
e.Cell.Controls.Add(new LiteralControl("<p></p>Pending: 0"));
}
}
}
}
protected void Calendar1_VisibleMonthChanged(object sender,

{
DateTime firstDate = e.NewDate.AddDays(-7);
DateTime lastDate = e.NewDate.AddMonths(1).AddDays(7);
dsleaveplanner = GetCurrentMonthData(firstDate, lastDate);
}
What I want is if there is no data for a date i want the default value Slot avalable: 10 and Pending: 0 to be displayed. And I want the slot available and pending to be displayed only once in each date. What am I missing here?
Thanks in advance

First of all create one sample class with your name
class Sample
{
public DateTime Date { get; set; }
public int SlotAvailable { get; set; }
public int Pending { get; set; }
}
And create a List<Sample>
List<Sample> samples = new List<Sample>();
Then change your foreach like
foreach (DataRow dr in dsleaveplanner.Tables[0].Rows)
{
nextDate = (DateTime)dr["date"];
MySqlConnection conn = new MySqlConnection("Server=localhost;Database=mydb;Uid=myid;Pwd=abc123;");
string cntdate = "SELECT COUNT(date) FROM approved WHERE date = #date";
string cntdate2 = "SELECT COUNT(date) FROM pending WHERE date = #date";
MySqlCommand cmd2 = new MySqlCommand(cntdate, conn);
MySqlCommand cmd3 = new MySqlCommand(cntdate2, conn);
cmd2.Parameters.AddWithValue("#date", nextDate);
cmd3.Parameters.AddWithValue("#date", nextDate);
conn.Open();
string count = cmd2.ExecuteScalar().ToString();
string count2 = cmd3.ExecuteScalar().ToString();
var slot2 = Convert.ToInt32(count);
Int32 slot3 = 10 - slot2;
string slot4 = slot3.ToString();
conn.Close();
samples.Add(new Sample { Date = nextDate, SlotAvailable = slot4, Pending = count2 });
}
And then simply check if the e.Day.Date is present in our date in List<Sample>s date like
if (samples.Any(x => x.Date == e.Day.Date))
{
e.Cell.BackColor = System.Drawing.Color.Orange;
Environment.NewLine.ToString();
e.Cell.ForeColor = System.Drawing.Color.Red;
e.Cell.Font.Size = 9;
e.Cell.Controls.Add(new LiteralControl("<p></p>Slot available:"));
e.Cell.Controls.Add(new LiteralControl(samples.Where(x => x.Date == e.Day.Date).FirstOrDefault().SlotAvailable.ToString()));
e.Cell.Controls.Add(new LiteralControl("<p></p>Pending:"));
e.Cell.Controls.Add(new LiteralControl(samples.Where(x => x.Date == e.Day.Date).FirstOrDefault().Pending.ToString()));
}
else
{
e.Cell.Font.Size = 9;
e.Cell.Controls.Add(new LiteralControl("<p>Slot available: 10</p>"));
e.Cell.Controls.Add(new LiteralControl("<p></p>Pending: 0"));
}

How to retrieve data from SQL Server and display as a task scheduler using asp.net and C#?

I want to create the attached task scheduler using asp.net and C#.
In SQL Server I have a table with these columns:
InstituteId, InstituteName, Address,
CareerDay2017 (date), CareerDay2018 (date), CareerDay2019 (date)
Dropdown list has values 2017, 2018, 2019. A button should be next to the dropdownlist.
When we select the year from dropdown list and click the button particular data should be retrieved and displayed as the image.
The career day details should be retrieved and colored the particular cell.
This is what I have tried, but it is incorrect. Hope you have taken my idea and help me.

As for the UI part, you need to place a breakpoint in the method that draws your UI and step through it while it is reading your data. You need to learn how to debug you code.
Just based off what you have posted, I think you have a bigger issue, you should not be declaring a SqlConnection at the class level, it should be in a method somewhere. For example:
public void GetCalendarData(int year)
{
// You need to use a parameter for the year instead of hard-coding it (note the #year)
string strCmd = #"SELECT InstituteId, InstituteName
FROM Institution
WHERE YEAR(CarrerDay2018) = #year
ORDER BY InstituteId";
using(var conn = new SqlConnection(connString))
using(var cmd = new SqlCommand(strCmd))
{
// add the #year parameter to the command
cmd.Parameters.AddWithValue("#year", year);
conn.Open();
var reader = cmd.ExecuteReader();
// setdata, createYearTable, etc.
conn.Close();
}
}
This way you are not holding a connection to the database for any longer than you need to. Also, I have put the connection and the command inside using statements, meaning that they will be disposed of properly by the garbage collector.

Reading database data and forwarding to variables

Can anyone point me to where I make a mistake, I want to put a new sql query where I will read the data from the database and put them in my function, and in the end they will be displayed at the exit in the colon ("stunden") which currently appears on the first query SUM (zei.ZPZ_Std100) AS ZPZ_Std100
This looks like my entire code in the button
using (SqlConnection db = new SqlConnection(ConfigurationManager.ConnectionStrings["TestControl.Properties.Settings.DB"].ConnectionString))
{
boAPI4.Login login = new boAPI4.Login();
string cS = login.GetConnectionString();
DataAccess dA = new DataAccess(cS);
int userID = dA.getLpeID(login.GetBoUserNr());
PRAESENZZEIT q = new PRAESENZZEIT();
q.ZPZ_LPE_ID = userID;
if (db.State == ConnectionState.Closed)
db.Open();
string query = "SELECT per.LPE_Nr, zei.ZPZ_LPE_ID, zei.ZPZ_Datum, SUM (zei.ZPZ_Std100) AS ZPZ_Std100" +
" FROM DB.dbo.Z_PRAESENZZEIT zei INNER JOIN DB.dbo.A_PERSONAL per ON zei.ZPZ_LPE_ID = per.LPE_ID" +
$" WHERE zei.ZPZ_Datum BETWEEN '{dtFromDate.Value}' AND '{dtToDate.Value}' AND zei.ZPZ_LPE_ID='{userID.ToString()}' GROUP BY per.LPE_Nr, zei.ZPZ_LPE_ID, zei.ZPZ_Datum ORDER BY zei.ZPZ_Datum, per.LPE_Nr;";
pRAESENZZEITBindingSource.DataSource = db.Query<PRAESENZZEIT>(query, commandType: CommandType.Text);
List<PRAESENZZEIT> listid = new List<PRAESENZZEIT>();
PRAESENZZEIT pra = new PRAESENZZEIT();
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["TestControl.Properties.Settings.DB"].ConnectionString);
string sql = "SELECT ZPZ_Von,ZPZ_bis FROM DB.dbo.Z_PRAESENZZEIT WHERE ZPZ_LPE_ID='196'";
con.Open();
SqlCommand cmd = new SqlCommand(sql, con);
SqlDataReader dr = cmd.ExecuteReader();
while (dr.Read())
{
pra.ZPZ_Von = Convert.ToDateTime(dr["ZPZ_Von"]);
pra.ZPZ_Bis = Convert.ToDateTime(dr["ZPZ_bis"]);
listid.Add(pra);
}
dataGridView1.DataSource = listid;
con.Close();
DateTime kommen = DateTime.Now;
kommen = pra.ZPZ_Von;
if (pra.ZPZ_Von.TimeOfDay < new TimeSpan(8, 5, 0))
pra.ZPZ_Von = new DateTime(pra.ZPZ_Von.Year, pra.ZPZ_Von.Month, pra.ZPZ_Von.Day, 8, 0, 0);
DateTime gehen = DateTime.Now;
gehen = pra.ZPZ_Bis;
TimeSpan arbeitszeit = pra.ZPZ_Bis - pra.ZPZ_Von;
}
Currently, at the exit I get 0.
So, I need data that pass through the datetime variable
This is how it goes through the variables but returns the result as if it did not address base data, what's the problem? I understand if time [ZPZ_VON 07:45] that the exit should be 08:00..

suppose there are 2 entries in the excelsheet file.When trying to import,it is inserting those 2 rows entries into the database table.but the problem is that, the reader does not stop its execution.After reading 2 rows entry,it is reading 3rd row which is blank.i have used dr.close and it keeps on reading the rows entries which is blank.

Instead of checking if there are rows left (dr.Read()) as your loop condition, you could check if the first cell of the row is blank (dr[0].ToString() != String.Empty)
string file_name = Path.GetFileName(FileUpload1.FileName);
string Excel_path = Server.MapPath("~/Excel/" + file_name);
FileUpload1.SaveAs(Excel_path);
OleDbConnection my_con = new OleDbConnection(#"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + Excel_path + ";Extended Properties=Excel 8.0;Persist Security Info=False");
my_con.Open();
OleDbCommand command = new OleDbCommand("select * from [Sheet1$]", my_con);
OleDbDataReader dr = command.ExecuteReader();
dr.Read();
while (dr[0].ToString() != String.Empty)
{
ex_id = dr[0].ToString();
string ex_uid = dr[1].ToString();
//get second row data and assign it ex_name variable
string ex_date = dr[2].ToString();
//get thirdt row data and assign it ex_name variable
string ex_dir = dr[3].ToString();
//get first row data and assign it ex_location variable
string ex_email = dr[4].ToString();
string ex_email1 = dr[5].ToString();
string ex_email2 = dr[6].ToString();
//string ex_company = dr[7].ToString();
string ex_company = dr[7].ToString();
string ex_contact = dr[8].ToString();
string ex_proposal = dr[9].ToString();
string ex_reason = dr[10].ToString();
...............
//Insert operation
...............
dr.Read();
}
dr.close();
my_con.close();
The premise of course is, that the first column is always filled if the rest of the row isn't blank.
If that isn't the case you can also check other columns in the loop condition.

there is various way of doing that
you can load excel data to datatable and then you can for loop for each row with perticular column name like this
string file_name = Path.GetFileName(FileUpload1.FileName);
string Excel_path = Server.MapPath("~/Excel/" + file_name);
DataTable dtExceldata = new DataTable();
FileUpload1.SaveAs(Excel_path);
OleDbConnection my_con = new OleDbConnection(#"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + Excel_path + ";Extended
Properties=Excel 8.0;Persist Security Info=False");
OleDbDataAdapter da = new OleDbDataAdapter("select * from [Sheet1$]", my_con);
da.Fill(dtExceldata);
if(dtExceldata.Rows.Count>0)
{
for (int i = 0; i <= dtExceldata.Rows.Count - 1; i++)
{
//assign value to variable
//like below
//string ex_uid = dtExceldata.Rows[i]["columnName"];
//then insert operation here
}
}

see this excel file
and the datatable in c#
this loop will repeat for only number of row in datatable then also i practically tried this and it only loop for number of row (e.g two times) but i found a bug that if you will enter two row then five blank row then some data it will give you blank value in data table check your excel file there may some blank value as shown in attechment
then also you can skip blank value by checking null value in row like this
for (int i = 0; i <= dtExceldata.Rows.Count - 1; i++)
{
if (!String.IsNullOrEmpty(Convert.ToString(dtExceldata.Rows[i]["fieldvalues"])))
{
//assign value to variable
//like below
//string ex_uid = dtExceldata.Rows[i]["columnName"];
//then insert operation here
}
}

how to saved different sheet from excel file to mysql database

I have a code that importing and displaying a excel file to datagridview and I'm wondering if you help me to how can I save those sheet from my excel file to my database in mysql?? My sheet name are 1st grading, 2nd grading and attendance, I'm using c#. Anyway here's my code:
private void btnSaved_Click(object sender, EventArgs e)
{
int qtr = 0;
string att_qtr = "ATTENDANCE";
MySqlConnection con = new MySqlConnection("Server = DESKTOP-9H7QBOH; Database = sti_spms; UID = root; Password = 1234;");
try
{
string query = "INSERT INTO tbl_secondsem_grades(STUDENT_NO, NAME, SUBJECT, SECTION, GRADE, INITIAL_GRADE, QTR)" + "Values(#STUDENT_NO, #NAME, #SUBJECT, #SECTION, #GRADE, #INITIAL_GRADE, #QTR)";
query += "INSERT INTO tbl_attendance(STUDENT_ID, NAME, SUBJECT, SECTION, TOTAL_ABSENCES)" + "Values(#STUDENT_ID, #NAME, #SUBJECT, #SECTION, #TOTAL_ABSENCES)";
MySqlCommand cmd = new MySqlCommand(query, con);
DataTable dt = new DataTable();
con.Open();
for (int i = 0; i < dataGridView1.Rows.Count -1; i++)
{
if(quarter.Equals("1st QTR"))
{
qtr = 1;
}
else if(quarter.Equals("2nd QTR"))
{
qtr = 2;
}
else if(quarter.Equals("3rd QTR"))
{
qtr = 3;
}
else if(quarter.Equals("4th QTR"))
{
qtr = 4;
}
else if (quarter.Equals("ATTENDANCE"))
{
att_qtr = "ATTENDANCE";
}
else
{
MessageBox.Show("Error!");
}
//int num = Convert.ToInt32(dataGridView1.Rows[i].Cells["STUDENT NO"].Value.ToString());
cmd.Parameters.AddWithValue("#STUDENT_NO", dataGridView1.Rows[i].Cells["STUDENT NO"].Value.ToString());
cmd.Parameters.AddWithValue("#NAME", dataGridView1.Rows[i].Cells["NAME"].Value.ToString());
cmd.Parameters.AddWithValue("#SUBJECT", dataGridView1.Rows[i].Cells["SUBJECT"].Value.ToString());
cmd.Parameters.AddWithValue("#SECTION", dataGridView1.Rows[i].Cells["SECTION"].Value.ToString());

cmd.Parameters.AddWithValue("#GRADE", dataGridView1.Rows[i].Cells["QG"].Value.ToString());
cmd.Parameters.AddWithValue("#QTR", qtr);
cmd.Parameters.AddWithValue("#STUDENT_NO", dataGridView1.Rows[i].Cells["STUDENT NO"].Value.ToString());
cmd.Parameters.AddWithValue("#NAME", dataGridView1.Rows[i].Cells["NAME"].Value.ToString());

cmd.ExecuteNonQuery();
cmd.Parameters.Clear();
}
}
catch (Exception ex)
{
MessageBox.Show("Data Sucessfully Saved!");
}
}

Quickie partial
...
MySqlCommand cmd = new MySqlCommand(query, con);
DataTable dt = new DataTable();
cmd.Paramters.Add("#STUDENT_NO", MySqlDbType.Int); .. guessing this is an int - otherwise choose type
cmd.Paramters.Add("#NAME", MySqlDbType.String);
... // add rest here
con.Open();
...
for (.. ) {
...
int studentno;
int.TryParse(dataGridView1.Rows[i].Cells["STUDENT NO"].Value.ToString(), out studentno);
cmd.Paramters["#STUDENT_NO"].Value = studentno;
cmd.Paramters["#NAME"].Value = dataGridView1.Rows[i].Cells["NAME"].Value.ToString();
...
}
