How to disable date deselect?

[wajira]

I'm using RAD Calender with Multiselect = 'False'.
When I click on an already selected date, the date get deselected.
I want to stop that.

Is there any property to do that or How Can I do that?

Hi,

Attach OnDateSelecting event to RadCalendar and try the following client side code.

js:

<script type="text/javascript">
    function OnDateSelecting(sender, args) {
        if (args._renderDay.IsSelected) {
            args.set_cancel(true);
        }
    }
</script>

Hi Shinu ,

It looks It works.
Thanx.

Does this solution still work?
When I try this script, it breaks the EnableMultiSelect="False"
In other words, multiple days can be selected despite multiselect being turned off.

I am using 2010.03.1109.40

Hi Samuel,

You can use the OnDateClick event to get the date that is about to be selected and then compare it with the current date. Here is a code sample:

var date = null;
        function OnDateSelecting(sender, args) {
            var currentDate = args.get_renderDay().get_date();
            var newDate = new Date(currentDate[0], currentDate[1], currentDate[2]);
            if (args.get_renderDay().IsSelected && isDatesEquals(date,newDate)) {
                args.set_cancel(true);
            }
        };

        function OnDateClick(sender, eventArgs)
        {
            var d = eventArgs.get_renderDay().get_date();
            date = new Date(d[0], d[1], d[2]);
        }

        function isDatesEquals(date1, date2)
        {
            if(date1.getFullYear() == date2.getFullYear() && date1.getMonth() == date2.getMonth() && date1.getDate() == date2.getDate())
            {
                return true;
            }
            else return false;
        }
