Hi,
I am using Rad Calendar for selecting multiple dates . I need to select many dates for some back end computation.
I also need to bind the dates again with the calendar control while retrieving the dates from DB. I dono the exact way of achieving this. I used the following code but it giving problem in "get_selectedDates()" function. I am using the latest Version only. Pls help me
function getSelected() {
            var d, text = '';
            var calendar = "<%= RadCalendar1.ClientID %>";
            var dates = calendar.get_selectedDates();
            for (var i = 0; i < dates.length; i++) {
                var date = dates[i];
                d = date[1] + '/' + date[2] + '/' + date[0];

                if (i == dates.length - 1) {
                    text = text + d;
                }
                else {
                    text = d + ',' + text;
                }
            }
            var textbox = document.getElementById('TextBox1');
            textbox.value = text;
        }

How to change special dates style?

Hi Everybody,

I developed a little project for try to undertand better the working of radcalendar control. In this development I havent knw how to change the special dates style.

In the page, there are two radcalendar controls and a button. The user selects any date from first radcalendar and then the user clicks on button.

There is a event button that gets all dates and then adds as special dates in the second radcalendar. Well, both radcalendar control has the style of Web20. I'd like that the special dates will be the same style of disable dates or dates that be outside of period of time.

This is the event button code:

foreach

(RadDate item in RadCalendar1.SelectedDates)

{

RadCalendarDay day = new RadCalendarDay();

day.Date = item.Date;

day.IsDisabled =

true;

day.IsSelectable =

false;

day.ItemStyle.CssClass =

"calendarHolidays";

RadCalendar2.SpecialDays.Add(day);

}

Following, css:

.calendarHolidays

a

{

color: red !Important;

background-color: #f2f2f2 !Important;

}

this class is inside of Calendar.Web20 css.

Could anyone help me plase??/

Thank you for all attention,

Carlos

Javascript can't find my treeview

Probably a really obvious mistake, but I have been scratching my head for a couple of hours now. I can't seem to get javascript to find my tree view, I started off in a splitter area, and then took it out, and have now created the most basic page I can to try and find a tree view with the Javascript API.

When I run this I get a Javascript error telling me

"Webpage error details

User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET CLR 1.1.4322; InfoPath.2; OfficeLiveConnector.1.3; OfficeLivePatch.0.0)
Timestamp: Mon, 16 Nov 2009 13:32:20 UTC

Message: 'tree' is null or not an object
Line: 67
Char: 18
Code: 0"

So it's not finding the tree, never mind the nodes. Any suggestions would be gratefully received.

}

CSS:

Possible to add onmouseover to appointments?

I'd like to implement my own version of a popup when the user mouses over an appointment on the schedule control. I've tried adding it to the attributes collection on both the Appointment object and the AppointmentControl object, but neither of these has worked. Is there a way to add this attribute to appointments?
