Tracy, Here is my code. If you don't mind can you help me out in resolving this issue. Thanks!
<mx:DataGrid id="myDataGrid" width="100%" dataProvider="{schedAdj_do}" textAlign="left" height="250" headerHeight="50" editable="true" cellEdit="updateData(event)"> <mx:columns> <mx:Array> <mx:DataGridColumn headerText="#" columnName="adj_num" width="50" editable="false" textAlign="left"/> <mx:DataGridColumn headerText="Type" columnName="adj_type" width="100" /> <mx:DataGridColumn headerText="Category" columnName="adj_category" width="150" /> <mx:DataGridColumn headerText="Terms" columnName="adj_amt_terms_desc" width="200" /> <mx:DataGridColumn headerText="{rptappl}" columnName="adj_reporter_applied_flag" width="50" /> <mx:DataGridColumn headerText="Sign" columnName="adj_sign" width="75" textAlign="center" /> <mx:DataGridColumn headerText="Factor" columnName="adj_factor" width="100" textAlign="right"/> <mx:DataGridColumn headerText="{ordappl}" columnName="adj_order_applied" width="75" textAlign="left" /> </mx:Array> </mx:columns> </mx:DataGrid>
function updateData(event:Object) { mx.controls.Alert.show("cellEdit event fired "); var colName:String= event.target.getColumnAt(event.columnIndex).columnName; var row:Number = event.itemIndex; var dataValue = event.target.getItemAt(row)[colName]; //mx.controls.Alert.show("event.columnIndex :"+event.columnIndex+newline+"colName : "+colName+newline+"new value : "+event.target.getItemAt(row)[colName]); myDataGrid.dataProvider.editField( event.columnIndex, colName, dataValue); }

Calling addItem() on the dataGrid is actually calling it on the dataProvider and physically adding the line.
Now, that line is empty, the "item" would be undefined (null?), and NOTE THIS: editing a datagrid cell does not automatically update the datagrid. You will need to use the editCell event to call editField() to update the dp with the entered data. I bet your dataProvider has a line but it is empty.

Hi, I would like to extend the scope of this thread by asking How to make this newly added row as a part of the dataprovider? What I mean is I am able to create a new row in datagrid by using your methodology. But when I try to access data in my POJO, I am getting nullpointer exception. That means, I think, the newly added row to grid is not truly added to dataprovider. Do I have to make any specific function call to make the newly added row attach to dataprovider? If this question is already discussed, please guide me with reference.

Here's a little mod that automatically adds the new row when you tab out of the last cell. The doLater reminder solved an aggravating problem I was having!
<?xml version="1.0"?> <mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml" xmlns="*"> <mx:Script><![CDATA[
function checkOnNav(oEvent:Object):Void { var iItemIndex:Number; var iColumnIndex:Number; switch (oEvent.type) { case "cellFocusOut": iItemIndex = oEvent.itemIndex; iColumnIndex = oEvent.columnIndex if (iColumnIndex == oEvent.target.columnNames.length - 1 && iItemIndex == oEvent.target.length - 1 ) { //leaving the last row, last column oEvent.target.addItem(); doLater(this,"focusLastRow",[oEvent]) } break;
}//switch (oEvent.type) }//checkOnNav
private function focusLastRow(oEvent:Object):Void{ var dg:mx.controls.DataGrid = oEvent.target; dg.setFocus(); dg.focusedCell = {columnIndex: 0, itemIndex: dg.dataProvider.length-1}; }//setFocusNextLine
]]></mx:Script> <mx:DataGrid id="grid" editable="true" cellFocusOut="checkOnNav(event)"> <mx:dataProvider> <mx:Array> <mx:Object name="manish" colour="red" /> <mx:Object name="abdul" colour="blue" /> </mx:Array> </mx:dataProvider> </mx:DataGrid>
</mx:Application>

<?xml version="1.0"?> <mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml" xmlns="*"> <mx:Script> function enterNewRow():Void { grid.addItem(); focusNewRow(); doLater(this, "focusNewRow"); } function focusNewRow():Void { grid.setFocus(); grid.focusedCell = {columnIndex: 0, itemIndex: grid.dataProvider.length-1}; } </mx:Script> <mx:DataGrid id="grid" editable="true"> <mx:dataProvider> <mx:Array> <mx:Object name="manish" colour="red" /> <mx:Object name="abdul" colour="blue" /> </mx:Array> </mx:dataProvider> </mx:DataGrid> <mx:Button label="Enter New Row" click="enterNewRow()" /> </mx:Application>
Note:
1. grid.addItem() will add a blank row 2. call focusNewRow() in the next frame using doLater()
