Day selection

[Shirya]

Hello,
i can't seem to figure out how to select several days in my calendar.
I have a list of dates that i would like to select in my calendar. How can i do this?
I set the property AllowMultipleSelect tro true and tried something like that but  no dates are selected:

For  each myDate in DateList

Me.RadCalendar1.SelectedDates.Add(myDate )

Next

thanx

[Shirya]

never mind: i had the time in my dates. I removed the time and now it show the selected date.
But i have another question: I would like to disable the days that are not in my DateList.
How can i do that?
thanks

Hi Shirya,

You can get an instance of any cell element in RadCalendar and set its properties such as the Enabled property. When you set Enabled = false then you will no longer be able to select that cell using the mouse or the keyboard.

Here is sample code which disables all cells in RadCalendar

For Each cell As CalendarCellElement In (TryCast(Me.radCalendar1.CalendarElement.CalendarVisualElement, MonthViewElement)).TableElement.Children
cell.Enabled = False
Next cell

You can check what is the current cell date using the Date property of CalendarCellElement class.

I hope that this will help you. Do not hesitate to contact me back if you have further questions.

Hello,
I tryed you solution and it works, but only in the current month.
when i navigate through my calendar, all the days are disable except the days in my date list.
I would like to enable only the days of the month  in my dateList.
How can i do that?

i try this too but stil the same result

 

For Each myCell As UI.CalendarCellElement In RadCalendarStartDate.RootElement.Children(0).Children(0).Children(2).Children(0).Children(1).Children
     If Not Me.Dates.Contains(myCell.Date) Then
        myCell.Enabled = False
    End If
Next

 

thank you
Shirya

Hello Shirya,

You could try also using the code (that disables cells) in the handler of the ViewChanged event of RadCalendar so that it is executed every time the user navigates to a different month.

You may also need to change the code a little bit so that it also enables cells for dates that are in your list.

I hope this helps.

All the best,

hello again,
Weekend and normal days do not have the same look when disabled. How can i have the same gray backcolor for all the disabled days (even if its not a weekend day) ?

[Boyko Markov]

Hello Shirya,

I think this issue is theme related and I have a very simple workaround. You can set the color properties of the calendar cells: BackColor, BackColor2, BackColor3, BackColor4, GradientStyle, etc.

Please take a look at the sample code below:

foreach (CalendarCellElement cell in (this.radCalendar1.CalendarElement.CalendarVisualElement as MonthViewElement).TableElement.Children)
{
     cell.BackColor = Color.Green;
}

Please do not hesitate to contact me if you have any other questions regarding RadCalendar.

            InitializeComponent();
            this.radDateTimePicker1.DateTimePickerElement.Opened +=new EventHandler(DateTimePickerElement_Opened);
           

   

        }

        private void DateTimePickerElement_Opened(object sender, EventArgs e)
        {
            CalendarTableElement table = ((this.radDateTimePicker1.DateTimePickerElement.GetCurrentBehavior() as
                RadDateTimePickerCalendar).Calendar.CalendarElement.CalendarVisualElement.Children[0].Children[1] as
                CalendarTableElement);
            foreach (CalendarCellElement cell in table.Children)
            {
                cell.Enabled = true;
               
                if (cell.Date.DayOfWeek != DayOfWeek.Monday)
                {
                    cell.Enabled = false;
                                     

                }

            }

Hello Anjan Guha,

This cannot be done with the current implementation of RadCalendar. The selection  cannot be canceled for a specific cell using the Enabled property. However this will be possible after we release the SP release this week.

Feel free to contact us again in case you have further questions after the SP1 release.
 

Best wishes,

I want to show the default calender month
how can i do that.
example.

if i click on the calender  icon of the date picker then the current month  calender opens
but i need to open some other months calender.
how can i do it?

thanx in advance

[Boyko Markov]

Hi DK,

Here is sample code which demonstrates how to show a month different than the current one when the user opens the RadCalendar popup in RadDateTimePicker:

1. Subscribe to the Opened event of the PopupControl

RadDateTimePickerCalendar calendarBehavior = this.radDateTimePicker1.DateTimePickerElement.GetCurrentBehavior() as RadDateTimePickerCalendar;
calendarBehavior.PopupControl.Opened += new EventHandler(PopupControl_Opened);

2. Set the calendar's FocusedDate property to any custom date.

void PopupControl_Opened(object sender, EventArgs e)
{
    DateTime myCustomDate = new DateTime(2000, 10, 20);
    RadDateTimePickerCalendar calendarBehavior = this.radDateTimePicker1.DateTimePickerElement.GetCurrentBehavior() as RadDateTimePickerCalendar;
    calendarBehavior.Calendar.FocusedDate = myCustomDate;
}

I hope this helps.
