Flex List selected entire list by default

I am currently working on a project in Flex and I am having a hard time having a l开发者_如何学Pythonist's contents ALL be selected by default. Wondering how to do this. Appreciate any help.

<mx:List id="list" dataProvider="{dp}" allowMultipleSelection="true"/>

I'm just trying to have the list all selected.

Try to use something like the following:

<mx:List id="list" dataProvider="{dp}" allowMultipleSelection="true" 
    creationComplete="event.currentTarget.selectedItems = event.currentTarget.dataProvider.source"/>

I ended up trying many different variations to get the list to be all selected. This is the one that ended up working.

var arr:Array = new Array();

for (var i:Number = 0; i < (list.dataProvider as ArrayCollection).length; i++) {

arr[i] = i;

}

list.selectedIndices = arr;
