DataGrid sort start/completion: specific associated events?

Question

Hi all,
A lot of my DataGrid sorts take a non-trivial amount of time.
So, I'd like to show a busy cursor while the operation runs. In
order to do this I'd need events associated with the start and
completion of the operation. Are there such events available?
Thanks!

This thread was "imported" from the old forums -- most, if not all, code seems to have disappeared. But here are the sort functions I posted:
function sortXML(source:XML, elementName:Object, fieldName:Object,
options:Object = null):XML
     // list of elements we're going to sort
     var list:XMLList=source.elements("*").(name()==elementName);
     // list of elements not included in the sort -
     // we place these back into the source node at the end
     var excludeList:XMLList=source.elements("*").(name()!=elementName);
     list= sortXMLList(list,fieldName,options);
     list += excludeList;
     source.setChildren(list);
     return source;
function sortXMLList(list:XMLList, fieldName:Object, options:Object =
null):XMLList
     var arr:Array = new Array();
     var ch:XML;
     for each(ch in list)
           arr.push(ch);
     var resultArr:Array = fieldName==null ?
           options==null ? arr.sort() :arr.sort(options)
           : arr.sortOn(fieldName, options);
     var result:XMLList = new XMLList();
     for(var i:int=0; i<resultArr.length; i++)
           result += resultArr[i];
     return result;
