You could do something like the following, which will set the selected date to July 4, 1980 and then set the DateChooser control’s displayed month and year to that same date:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application name="DateChooser_selectedDate_test"
        xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <mx:Date id="dat" fullYear="1980" month="6" date="4" />

    <mx:DateChooser id="dateChooser"
            selectedDate="{dat}"
            displayedYear="{dat.fullYear}"
            displayedMonth="{dat.month}" />

</mx:Application>

The previous code will give a couple of binding warnings saying:
(a) Data binding will not be able to detect assignments to “fullYear”.
(b) Data binding will not be able to detect assignments to “month”.

The example still works, but if you don’t like those warnings, you could always set the properties using ActionScript instead, as seen in the following example:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application name="DateChooser_selectedDate_test"
        xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <mx:Script>
        <![CDATA[
            import mx.events.CalendarLayoutChangeEvent;

            private function dateChooser_change(evt:CalendarLayoutChangeEvent):void {
                var selDat:Date = dateChooser.selectedDate;
                dateChooser.displayedYear = selDat.fullYear;
                dateChooser.displayedMonth = selDat.month;
            }
        ]]>
    </mx:Script>

    <mx:DateChooser id="dateChooser"
            change="dateChooser_change(event);">
        <mx:selectedDate>
            <mx:Date fullYear="1980" month="6" date="4" />
        </mx:selectedDate>
    </mx:DateChooser>

    <mx:Button id="btn"
            label="Set new selectedDate"
            click="dateChooser.selectedDate = new Date(1976, 8, 9);" />

</mx:Application>

Try clicking on Aug 6th, pressing the Shift key, and then pressing on Aug 22nd.
It should highlight each of the days between the two dates, set the range, and list the number of days as 17.

If you press the Ctrl key, I believe it selects each day individually instead of as a range/series.

We are working with Flex Builder 3 and We need to select multiple days in a calendar
without pressing the Ctrl or Shift keys. Is it possible?

Thanks

First, very big thank you for having responded …
I never thought you were answering me still thank you very much
This site told me everything about Flex and I hope with all my heart that will never end …
This is the solution that I was looking for …
You are the best, MANY THANKS

I’m sure there is a better, more efficient way, but maybe this helps:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <mx:Script>
        <![CDATA[
            import mx.events.CalendarLayoutChangeEvent;
            import mx.utils.ObjectUtil;

            private var msInDay:uint = 1000 * 60 * 60 * 24;

            private function dateChooser_change(evt:CalendarLayoutChangeEvent):void {
                // textArea.text = ObjectUtil.toString(dateChooser.selectedRanges);
                textArea.text = "";
                if (dateChooser.selectedRanges.length > 0) {
                    var ranges:Object = dateChooser.selectedRanges[0];
                    var numDays:uint = (ranges.rangeEnd.time - ranges.rangeStart.time) / msInDay;
                    var idx:uint;
                    var retDate:Date;
                    for (idx = 0; idx <= numDays; idx++) {
                        retDate = new Date(ranges.rangeStart.time);
                        retDate.date += idx;
                        textArea.text += retDate.toDateString() + "\n";
                    }
                }
            }
        ]]>
    </mx:Script>

    <mx:DateChooser id="dateChooser"
            allowMultipleSelection="true"
            change="dateChooser_change(event);" />

    <mx:TextArea id="textArea"
            editable="false"
            selectable="false"
            width="320"
            height="240" />

</mx:Application>
