How to find the number of returned objects from an Actionscript getter function?

Question

In my Flex project, I have a service function getItems() that returns me a collection/array of Item objects.

The function runs an SQL statement like SELECT * FROM table. I therefore do not want to use a SELECT COUNT SQL statement.

I know that if I use a Flex spark:DataGrid, I can easily get the length of the datagrid to know the number of rows (which in my case, would be the number of objects returned by my getItems() function). However, I am using an mx:AdvancedDataGrid and it is not possible to get the length by the same means as with the spark:DataGrid.

Actually, I need to dynamically create a set of labels with text={ItemName}. Using a Vbox and a for loop, I am able to create a list of labels. At the moment, I have a random number for the delimiter in my for loop. I just need to get the number of objects returned by my getItems() function. I can then put that number in the for loop and the job is done.

At least, this is how I plan to do this task.

Is there a better way to do this?

PS: I have Googled extensively, but I could not find any working examples for what I want to do.

Suggestions are welcome and StackOverflow is fabulous!

[EDIT] I eventually used an mx:Repeater to do the task described above.

Answer 1

how about this:

private function getItemsResultHandler(event:ResultEvent):void
{
    var items:ArrayCollection = new ArrayCollection();
    items = event.result as ArrayCollection;

    trace(items.length);
}
