Yes, when you use one of the dataProvider API methods. When you do: myDataGrid.removeItemAt(), you are really doing myDataGrid.dataProvider.removeItemAt().
Note: When you update a cell in an editable datagrid column, the data is NOT automatically modified in the dataProvider. You must call editField() in the updateField event handler.

When I create a <mx:Model of data and bind that to a control, the control alters the data from the original <mx:Model state? -----Original Message----- From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Manish Jethani Sent: Friday, May 06, 2005 13:52 To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] Reloading Data Question On 5/6/05, David Terry <[EMAIL PROTECTED]> wrote: > Or is it going to be some like... > var objData:Object; > > objData = catalog.product.clone(); See this: <?xml version="1.0"?> <mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml" xmlns="*"> <mx:Script> import mx.utils.ObjectCopy; function copyObject(source:Object):Object { var newObject:Object = ObjectCopy.copy(source); ObjectCopy.copyProperties(newObject, source); return newObject; } </mx:Script> <mx:Model id="model"> <root> <item> <creature>elephant</creature> <legs>4</legs> </item> <item> <creature>human</creature> <legs>2</legs> </item> </root> </mx:Model> <mx:DataGrid id="grid" dataProvider="{copyObject(model.root).item}" /> <mx:Button click="grid.removeItemAt(0)"> <mx:label>grid.removeItemAt(0)</mx:label> </mx:Button> <mx:DataGrid id="grid2" dataProvider="{model.root.item}" /> </mx:Application> copyObject() makes a copy of the object. Clicking on the "removeItemAt(0)" button removes the 1st item from the first grid only. So the original data provider object (which the second grid uses directly) is not modified. Yahoo!
