Question

I have a datagrid in my code that looks like this:

<s:DataGrid id="dg">
  <s:ArrayCollection id="ac">
    <s:DataItem ../>
    <s:DataItem ../>
  </s:ArrayCollection>
</s:DatGrid>

I am trying to have a separate label (by default) show the data from a particular cell after sorting the data in a particular way.

For Example:

DataGrid shows:

Date  Type
----  ----
8     yes      
12    no
6     this
7     that

Label: 6 (First date after sorting in ascending order)

Any easy way I can do this in ActionScript (or otherwise)? Should I try to work with the ArrayCollection component or the DataGrid?

Thanks,

Figured it out, using the sorting ArrayCollection reference. Used two different methods for sorting and extracting:

Sorting:

private function sortFunction(a:Object, b:Object, array:Array = null):int
{
  ..my sorting code..
}

public function Grid_onLoad(event:Event):void
{
  var sort:Sort = new Sort();
  sort.compareFunction = sortFunction;
  items.sort = sort;
  items.refresh();
}

Extraction:

public function FirstDate():String
{
  return items.getItemAt(0).Date;
}

Then its just a matter of calling the functions appropriately:

<s:DataGrid id="items" initialize="Grid_onLoad(event)">
  <s:ArrayCollection id="ac">
    <s:DataItem ../>
    <s:DataItem ../>
  </s:ArrayCollection>
</s:DatGrid>

<s:Label text="{FirstDate()}"/>
