I would store the CB's DP somewhere so you can get at it w/o creating an editor.

The editor for the cell is a combobox. What I'm doing is taking the data value sent down for that cell (a number), looking it up in the dataprovider of the combobox and displaying the corresponding label in my custom Label widget. What I'm wondering is if this is the best way to do it. In particular, the part that concerns me is that I'm creating an instance of the combobox editor to get the dataprovider collection to search. Any thoughts would be greatly appreciated. Thanks, John override public function set data(value:Object):void { super.data = value; var cbr:ComboBoxRenderer; // will contain renderer for this cell var dg:DataGrid; // reference to grid containing this cell var dp:ArrayCollection; // dataProvider of selected cell's comboBox if (listData != null) { dg = DataGrid(listData.owner); cbr = dg.columns[listData.columnIndex].itemEditor.newInstance(); dp = cbr.dataProvider as ArrayCollection; // now iterate through dp to find a matching data value, when found put its label in the Label widget var dpLen:int = dp.length; for (var j:int=0; j<dpLen; j++) { if (dp.getItemAt(j).data == data[DataGridListData(listData).dataField]) { // found match this.text = dp.getItemAt(j).label; // + " " + dp.getItemAt(j).data; trace('found LabelWithDownArrow'); return; } } // not found, so show comboBox prompt this.text = cbr.prompt; } }
