RE: [flexcoders] Problem in sorting XMLList collection as a dataProvider for the list
I would use a sort function, so I could debug any problems.
I'd also suggest an e4x expression instead of the loop.

Subject: [flexcoders] Problem in sorting XMLList collection as a
dataProvider for the list
Hi Guys
I am trying to sort the xmllist collection which is the dataprovider for the
list. As the implementation of name-value pairs, i am displaying the entries
in form of string in List and would like to sort all the data displayed in
the List alphabetically, I am making a call through amfphp call to grab data
from backend and populate XMLListCollection but now I need to sort the data
in the list. Below is the code,Can anyone please help me where I am messing
things up. Also please let me know if there is any question regarding the
code and if there is better way of doing it.
Thanks

If you have a labelfunction, you'll probably need a custom sortcompare function

Re: [flexcoders] Problem in sorting XMLList collection as a dataProvider for the list
Hi Thanks for replying
What does we mean by custom sort compare function, Can we provide any
examples of both sort and sort compare functions or little more details
about what and how does we do that?
Thanks much fro your help
