Sorry, forgot to provide my sortable DataGrid:
package CustomComponents
{
import mx.collections.*;
import mx.controls.DataGrid;
import mx.controls.dataGridClasses.*;
import mx.events.DataGridEvent;
public class sortableDataGrid extends DataGrid
{
public function sortableDataGrid()
{
super();
addEventListener("headerRelease", headerReleaseHeandler);
}
public var sortIndex:int = -1;
public var sortColumn:DataGridColumn;
public var sortDirection:String;
public var lastSortIndex:int = -1;
public var col:String;
public function headerReleaseHeandler(event:DataGridEvent):void
{
col = columns[event.columnIndex].dataField;
}
}
}
