Each time a date is picked on the DateChooser an "change" event is dispatched. By having a function handle the change event, the function can extract the information from the XML and move it to the TextArea.
<mx:DateChooser change="handleDatePick(event)" />
<mx:TextArea id="output" />
I'm going to assume your XML data is in a variable called "xmldata"; you'll have to figure out how to populate it.
The following code goes into a <mx:Script> block in your MXML file:
private function handleDatePick( event:Event ) : void
var chooser:DateChooser = event.target as DateChooser; // just to make it easier to understand the code
var d:Date = chooser.selectedDate; // the date the user picked. becareful, it can be null if the person picks the date already selected
if( d == null ) return;
var node:XML = xmldata..(@date == d.toDateString()); // this will take some explanation below
output.text = node.value; // the item in the XML node you want to see in the TextArea
} // done
OK, Let's assume your XML data looks like this:
<node date="Thu Jan 31 2008"><value>This is a test</value></node>
<node date="Thu Feb 14 2008"><value>This is Valentine's Day</value></node>
So each <node> in the XML has a date attribute. In the statement above (@date == d.toDateString()) will select the <node> which has a date that matches the formatted date selected by the user. If the user picked Feb 14, 2008, the d.toDateString() should match it.
Keep in mind that the user might select a date that doesn't match anything in your XML.
That's the idea. I can't put in any more detail because I don't know what your XML looks like. If your date isn't in a format that the Date format functions produce, you can use the <mx:DateFormatter> to make a value you can use for comparison.
This was exactly the beautiful sollution I was looking for. Thanks! However I feel really emberresed cause I can't figure out how to populate it.
I have succeeded to populate DataGrids through HttpService but that's because I found complete code examples on how to do it... To populate the it through a external xml that is called with HttpService would be the the preferable way as I see it.
A Question: I will probably buy a support program. Which program do I need (gold or platinum)? (I, one person, want to learn the program on a basic level and pass the hurtles as quick as possible with code examples). Are you working at the support?
Best regards, Tobias
