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.

 So let me try to understand this - I'm coming from a .Net world.

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?

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.
