combo box date validation

[j2eesatish]

Hi,
As per our requirement, we need to put combo boxess for date input. we are
giving the user to input as dd month year format from the given combos. Can you
give me idea how to validate the date(feb 31 ..) from the given inputs. If it
is textbox, it will be ok. but our need is very particular about, comboboxes.

Thanks

A DateValidator can validate against comboboxes as you describe. Here is an
example. With the following code, try entering an invalid date such as Feb.
31, and then pressing the Submit button; you will see a red border around the
Day field, and when you hover over it, you will see text that says, "Enter a
valid day for the month."


<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
creationComplete="init()">
<mx:HBox>
<mx:ComboBox id="day" prompt="day" rowCount="31" dataProvider="{days}" />
<mx:ComboBox id="month" prompt="month" rowCount="12" dataProvider="{months}" />
<mx:ComboBox id="year" prompt="year" rowCount="20" dataProvider="{years}" />
<mx:Button label="Submit" id="submit" />
</mx:HBox>

<mx:DateValidator
daySource="{day}" dayProperty="selectedItem"
monthSource="{month}" monthProperty="selectedItem"
yearSource="{year}" yearProperty="selectedItem"
trigger="{submit}" triggerEvent="click"
/>

<mx:Array id="years" />
<mx:Array id="days" />
<mx:Array id="months" />

<mx:Script>
<![CDATA[
private function init():void
{
var i:int;
for (i = 1900; i <= 2006; ++i)
years.push(i);
for (i = 1; i <= 31; ++i)
days.push(i);
for (i = 1; i <= 12; ++i)
months.push(i);
}
]]>
</mx:Script>
</mx:Application>

Thanks a lot!
The code looks fine. It will bbe exactly suited for our requirement. But, i
am getting some errors while executing the code. here the given exampel include
the line <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
creationComplete="init()">.
but our application is <mx:Application
xmlns:mx="http://www.macromedia.com/2003/mxml" initialize="loadme()">

Will this exaple will not suite for the macromedia mxml form? i ve change as
adobe. but the application is not able to recognize this!. Can you give me some
help on this!


Thanks

You must be running version 1.5.

There is enfough difference between the tow to make reverse migration very
difficult. Using the docs and this example, though, you might be able to see
what is needed.

If you indicate the Flex version you are using in you post, it will save
everyong a lot of time.
