hi guys

I have my customgrid like this

public class CustomGrid extends VBox
{

private var id:String = "";
            
private function buildColumn(headers:Object,fields:Object):void{
dataGrid.addEventListener(flash.events.KeyboardEvent.KEY_UP,createAutoPopulate);
dataGrid.addEventListener(AdvancedDataGridEvent.ITEM_EDIT_END,itemEditEndHandler);
}

private function createAutoPopulate(event: flash.events.KeyboardEvent) : void {      
PopUpManager.addPopUp(tradeLookUp.dataGrid, this, false);      //show data
PopUpManager.centerPopUp(tradeLookUp.dataGrid);     //center popup
tradeLookUp.dataGrid.addEventListener(CheckBoxEvent.CHECKBOX_TOGGLED,populatedata);

}

private function itemEditEndHandler(event:AdvancedDataGridEvent):void{
if(event.currentTarget.columns[event.columnIndex].editable){
use 'id' here  
 }
}

private function  populatedata ( event:CheckBoxEvent ) : void {
id = event != null && event.data != null ? event.data.userId : "";
}

}

buildColumn()  is the first function which is called.

createAutoPopulate()  is second function which is called

itemEditEndHandler()  is the third function which is called

populatedata()  is the last function which is called


but the problem is i want populatedata() to be the third function which should be called and
itemEditEndHandler() should be called last.

from populatedata() i will have the 'id' which i can use in itemEditEndHandler().

any idea how i can set the priorities? i want populatedata()  to be called before itemEditEndHandler().

thnks

royjayd,
The first problem you cannot use "id" variable name in AS classes because id already declared in UIComponent

Another problem I cannot create valid project using your custom class. Please can you attach a working example.

If you can attach a whole project it's better. Don't worry I can read any code

Those methods will be called when the corresponding event is "seen" or "heard", so imo if you want the methods to be called in that specific order, you have to make sure that the events occur in that specific order. But I'm afraid that is somehting you don't control, do you?
Why is that specific order important to you? Maybe you have to rethink that...

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!
