Datasource to asp calendar

I'm trying to bind mysql data to asp:calendar but its not working. I need to display the data in mysql table slotavailable column according to the date column. How can I get it into the calendar cells?
<asp:Calendar ID="cal2" runat="server" Width="50%" DayField="Date" OnDayRender="Calendar1_DayRender"
BackColor="Orange" NextMonthText="Next" PrevMonthText="Prev" >
<DayStyle CssClass="days" VerticalAlign="Top" Font-Name="Arial" Height="80px" BackColor="lightYellow" />
<TodayDayStyle BackColor="Orange" />
<OtherMonthDayStyle BackColor="LightGray" ForeColor="DarkGray"/>
</asp:Calendar>
Below would be the cs code to fetch data
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
cal2.VisibleDate = DateTime.Today;
FillLeaveplannerDataset();
}
}
protected void FillLeaveplannerDataset()
{
DateTime firstDate = new DateTime(cal2.VisibleDate.Year, cal2.VisibleDate.Month, 1);
DateTime lastDate = GetFirstDayOfNextMonth();
dsleaveplanner = GetCurrentMonthData(firstDate, lastDate);
}
protected DateTime GetFirstDayOfNextMonth()
{
int monthNumber, yearNumber;
if (cal2.VisibleDate.Month == 12)
{
monthNumber = 1;
yearNumber = cal2.VisibleDate.Year + 1;
}
else
{
monthNumber = cal2.VisibleDate.Month + 1;
yearNumber = cal2.VisibleDate.Year;
}
DateTime lastDate = new DateTime(yearNumber, monthNumber, 1);
return lastDate;
}
protected DataSet GetCurrentMonthData(DateTime firstDate, DateTime lastDate)
{
DataSet dsMonth = new DataSet();
MySqlConnection con = new MySqlConnection("Server=localhost;Database=mydb;Uid=myid;Pwd=abc123;");
MySqlCommand cmd = new MySqlCommand("SELECT * FROM dummy WHERE date >= #firstDate AND date < #lastDate", con);
cmd.Parameters.Add(new MySqlParameter("#firstDate", firstDate));
cmd.Parameters.Add(new MySqlParameter("#lastDate", lastDate));
MySqlDataAdapter mysqlDataAdapter = new MySqlDataAdapter(cmd);
try
{
mysqlDataAdapter.Fill(dsMonth);
}
catch { }
return dsMonth;
}
protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
{
DateTime nextDate;
if (dsleaveplanner != null)
{
foreach (DataRow dr in dsleaveplanner.Tables[0].Rows)
{
nextDate = (DateTime)dr["date"];
var slot = dr["slotavailable"];
if (nextDate == e.Day.Date)
{
e.Cell.BackColor = System.Drawing.Color.Pink;
}
}
}
}
protected void Calendar1_VisibleMonthChanged(object sender,
MonthChangedEventArgs e)
{
FillLeaveplannerDataset();
}
How can get the slot column data into the calendar cell?

You please make sure that your nextDate and e.Day.Date are matches and then change in your code like
e.Cell.Controls can add any text to your cell
protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
{
DateTime nextDate;
if (dsleaveplanner != null)
{
foreach (DataRow dr in dsleaveplanner.Tables[0].Rows)
{
nextDate = (DateTime)dr["date"];
var slot = dr["slotavailable"];
if (nextDate == e.Day.Date)
{
//This is the line where we add slotavailable column data
e.Cell.Controls.Add(new LiteralControl($"<p>{slot}</p>"));
e.Cell.BackColor = System.Drawing.Color.Pink;
}
}
}
}
The output will be
The advantage of e.Cell.Controls you may add html button or span or image or any else as your need
And e.Cell.Controls.Clear(); may help you to clear all controls related to particular cell
Try once may it help you

Update/Delete buttons inside DataGridView not working after filtering results

C# winform application: i added buttons in datagridview in every row for (update,delete). it works fine but when i search data in this gridview the buttons doesn't work on search results.
Here is my code.
namespace MyBusiness

Saving DATETIME datatype to MySQL

I created a gridview in asp.net which has two columns of DATETIME datatype, when I connected to mysql database to save it within, it shows me an error " Incorrect datetime value: '01/01/2017 00:07:26' for column 'LogInDate_Time' at row 1" in cmd.ExecuteNonQuery(); line

Display date selected in one form to another form

I want to display the date which is selected in another form using monthCalender control..
Here is my code..
private void monthCalendar1_DateSelected(object sender, DateRangeEventArgs e)
{
ActivityScheduler frm1 = new ActivityScheduler();
frm1.Show();
}
private void ActivityScheduler_Load(object sender, EventArgs e)
{
if (con.State == ConnectionState.Open) { con.Close(); }
con.Open();
RemainderPopUp frm = new RemainderPopUp();
string s = "select * from [Activity_Scheduler]";
SqlCommand sCmd = new SqlCommand(s, con);
SqlDataAdapter da = new SqlDataAdapter(sCmd);
DataSet ds = new DataSet();
da.Fill(ds, "[Activity_Scheduler]");
datagridActivityScheduler.DataSource = ds.Tables[0];
datagridActivityScheduler.AllowUserToAddRows = true;
DataTable dt = new DataTable();
dt = ds.Tables["Activity_Scheduler"];
if (dt == null)
{
datagridActivityScheduler.Rows[0].Cells[3].Value = frm.monthCalendar1.SelectionRange.Start.ToShortDateString();
MessageBox.Show(datagridActivityScheduler.Rows[0].Cells[3].Value.ToString());
}
con.Close();
}
It is displaying the correct value in messagebox..but the value is not displaying in datagridview...
Plz anybody help me out..

Try Following Code :
form_load()
{
private string myDate="1999/12/12";
// Declare a Date property of type string:
public string Name
{
get
{
return myDate;
}
set
{
myName = value;
}
}
private void monthCalendar1_DateSelected(object sender, DateRangeEventArgs e)
{
ActivityScheduler frm1 = new ActivityScheduler();
ActivityScheduler.myDate = frm.monthCalendar1.SelectionRange.Start.ToShortDateString()
frm1.Show();
}
Now you can get date on other form as :
string myDate = frm1.myDate();
Let me know if any queries.
