Disable column's header

Question

I have a custom header renderer for one of datagrid columns. I want when I click on it to disable the header.
Here is my code:
package  
modulecode{
 import flash.events.Event; 
import flash.system.*; 
import mx.containers.VBox; 
import mx.controls.Image; 
import mx.controls.listClasses.BaseListData; 
import mx.events.DynamicEvent;[
Event(name="addEvent", type="mx.events.DynamicEvent")] 
public class newSalesAccountHeaderGrid extends VBox{
private var _listData:BaseListData; 
public function newSalesAccountHeaderGrid(){
super();}
override protected function createChildren() : void{
if (deleteIcon == null){
var deleteIcon:Image = new Image();deleteIcon.buttonMode =
true;deleteIcon.useHandCursor =
true;deleteIcon.toolTip =
"Add Account";deleteIcon.addEventListener(
"click", onAddAccountClick);Security.allowDomain (
"*");deleteIcon.source =
"D:/projects/sfcs/assets/plus.gif";addChild(deleteIcon);
validateNow();
protected function onAddAccountClick(event:Event):void{
enabled =
false; 
var dynEvent:DynamicEvent = new DynamicEvent("addEvent", true);dynEvent.data = data;
dispatchEvent(dynEvent);
The header will become disable, but because of the code that runs in addEvent it wil get enabled right away.
accounts.addEventListener(
"addEvent", onAddAccountEvent, false, 0, true);
private  
function onAddAccountEvent(event:DynamicEvent):void{
var newAccount:XML = XML(accounts.dataProvider[0]).copy();newAccount.ccompany =
"";newAccount.ccustno =
accounts.dataProvider.addItemAt(newAccount, accounts.dataProvider.length); // this will cause the header become enabled.
accounts.scrollToIndex(accounts.dataProvider.length - 1);
 accounts.selectedIndex = accounts.dataProvider.length - 1;
 accounts.editedItemPosition = {columnIndex:0, rowIndex:accounts.selectedIndex};
Any idea why it works that way?
Thanks

Hi There,
Im not sure what you are asking for, but if you want
to populate a dropdown from data from database, this
will help

Thanks
KNo, I know how to bind the dropdown directly to a Database this is simply.
The steps of my idea:
1. drag and drop a table.
2. Bind to a database table.
3.drag and drop a dropdownlist.
4. Obtain only the visible fields in the table (When I bind the data to table, I can select with table layout option the database fields to display.).
The idea is search by column in the table. The user selects in the dropdown the column and then search a word.
The 4 step is difficult for me.
Thank's
