{
_xlcdatagrid2.removeAll();
var numElements:int = _xlcdatagrid2.length;

i figure out the AS code but when i use the datachange in my datagrid comonent i get this error undefined method any ideas?
....
private function AutoB():void{
if (_xlcdatagrid2.length >= 2)
{
this._xlcdatagrid2.removeItemAt(0);
}
}
...
<mx:datagrid>
dataChange="datagrid2.selectedIndex.AutoB()"
