AS 2.0 Display Item in Datagrid in the order it was chosen and Remove Selected Item

programming flash
1

Hello Community,

I am in search of finding a way to display shopping cart items in a flash 8 datagrid in the order it was chosen by the user & also to ability to delete an item if the user choses. Currently I have the items displaying however they are displaying in a position as it is stored and called in the array.

Ex:


//Create a dataProvider to add some data to the Datagrid
  data_array = new Array();
  data_array.push(myArr, myArr2, myArr3);
  cart.dataProvider = data_array;

As far as deleting an item I have found this snippet of code on the forums but it will not delete the item.


// Create listener object for DataGrid to remove selected item.
var listener_obj:Object = new Object();
listener_obj.headerRelease = function(evt_obj:Object) {
cart.dataProvider.removeItemAt(cart.selectedIndex)

Any help is greatly appreciated. See below for complete coding. Thank you in advance!
