Hi, I am newbie to Flex, I has a question to display the currently selected item from the DropDownList control(s) in the application. For example totalscreen that drop down with [1, 2, 3, 4] if 3 is selected then the only items in localscreen drop down will be [1, 2,3] and if the 2 is selected,for the nextworkscreen will only have 1 is display. I am using the dropdownlist and ArrayCollection.

 

enter image description here

private function updateLocal(event:IndexChangeEvent):void

{

               var aLocal:Array = [];

               var idx:uint;

               var length:uint = totalscreenSelect.selectedItem.data;

               for(idx=0; idx<length; idx++)

               {

                       aLocal.push({data:"label"+idx});

               }

}

 

 

i try to use Array and  using ArrayCollection too, however there are error also.

 

<s:DropDownList id="totalscreenSelect" dataProvider="{_dataProviders}" change="updateLocal(event);"/>

 

 

 

Any thoughts on if this is possible and if so how to implement it would really be appreciated.

 

Thanks in advance.
