Calendar Controls in Webforms

I want to take the selected date from the calendar control and pass to the argument.

protected void Calendar1_SelectionChanged(object sender, System.EventArgs e)
{
_availebletimeSlotsRoom1 = new BindingList<string>(_allTimeSlots.ToList());
_availebletimeSlotsRoom2 = new BindingList<string>(_allTimeSlots.ToList());
_availebletimeSlotsRoom3 = new BindingList<string>(_allTimeSlots.ToList());
_availebletimeSlotsRoom4 = new BindingList<string>(_allTimeSlots.ToList());
DLAvailTS1.DataSource = _availebletimeSlotsRoom1;
DLAvailTS2.DataSource = _availebletimeSlotsRoom2;
DLAvailTS3.DataSource = _availebletimeSlotsRoom3;
DLAvailTS4.DataSource = _availebletimeSlotsRoom4;
UpdateRoom(1, e.Start, _availebletimeSlotsRoom1); //ERROR HERE:'EventArgs' does not contain a definition for 'Start' and no extension method 'Start' accepting a first argument of type 'EventArgs' could be found (are you missing a using directive or an assembly reference?)
UpdateRoom(2, e.Start, _availebletimeSlotsRoom2);
UpdateRoom(3, e.Start, _availebletimeSlotsRoom3);
UpdateRoom(4, e.Start, _availebletimeSlotsRoom4);
}

This procedure starts after a change of the selected dates in the Calendar1 control.

Parameter 'e' does not have not property Start.

How can I get the Start from the Calendar Object

Hi Sachin

I have a VB-Windows forms system for booking 4 rooms and it is working in VB -

It loads all the available booking time slots for a sleected date and only displays the available time slots for a selected date for each room

I was trying to convert it to WebForms using C# - I need to update the
Public Class Form1
Private db As DSEventBooking
Private _availebletimeSlotsRoom1 As BindingList(Of String)
Private _availebletimeSlotsRoom2 As BindingList(Of String)
Private _availebletimeSlotsRoom3 As BindingList(Of String)
Private _availebletimeSlotsRoom4 As BindingList(Of String)
Private _allTimeSlots As IList(Of String)
Private Sub MonthCalendar1_DateSelected(ByVal sender As Object,
ByVal e As System.Windows.Forms.DateRangeEventArgs) Handles MonthCalendar1.DateChanged
_availebletimeSlotsRoom1 = New BindingList(Of String)(_allTimeSlots.ToList)
_availebletimeSlotsRoom2 = New BindingList(Of String)(_allTimeSlots.ToList)
_availebletimeSlotsRoom3 = New BindingList(Of String)(_allTimeSlots.ToList)
_availebletimeSlotsRoom4 = New BindingList(Of String)(_allTimeSlots.ToList)
Room1AvailTSListBox.DataSource = _availebletimeSlotsRoom1
Room2AvailTSListBox.DataSource = _availebletimeSlotsRoom2
Room3AvailTSListBox.DataSource = _availebletimeSlotsRoom3
MainAvailTSListBox.DataSource = _availebletimeSlotsRoom4
UpdateRoom(1, e.Start, _availebletimeSlotsRoom1)
UpdateRoom(2, e.Start, _availebletimeSlotsRoom2)
UpdateRoom(3, e.Start, _availebletimeSlotsRoom3)
UpdateRoom(4, e.Start, _availebletimeSlotsRoom4)
End Sub

there is no Start property of calender, what do you mean when you say e.start?
If you want to get the selected date in your event then use like below
void Calender1_SelectionChanged(Object sender, EventArgs e)
     {
    var dateSelected=  Calendar1.SelectedDate;
     }
