something following should started. call creategrid() createchildren() override or initialize event listener.

note variables declared here need class variables make them accessible.

private function creategrid() {     var metricsgrid:grid = new grid();     //set other properties on metricsgrid      var cashmetricsgridheaderrow:gridrow = new gridrow();     //set other properties on metricsgrid      var item:griditem = new griditem();     //set other properties on griditem      var label:label = new label();     label.text = gettodaysdatewithtitle();      item.addelement(label);     cashmetricsgridheaderrow.addelement(item);     metricsgrid.addelement(cashmetricsgridheaderrow);      this.addelement(grid); }
