<mx:ComboBox dataProvider="{myLevels}" ...
This should set you up to use the myLevels in every ComboBox.
The comboBox has built-in logic to set the selectedItem based on what it
sees in the data property. In your case you might want to override the
data setter and choose selectedIndex then.
FWIW, using VBox to wrap will be slower than ComboBox straight up.

First off, reinstate the VBox. The override the setter data
(value:Object). There you can either set the cb's dataProvider like
cb.dp = data.someObject
or if you are doing it in MXML, you can bind the dataprovider of the CB
to some expected property of the data property of the VBox.
Doing it via script is a bit tricky, because if your data value doesn't
contain the targeted property it will throw a runtime error.

OK, now I've gotten rid of the VBox, but still do not see how I can set
a different dataProvider to the comboBox, or dynamically set the
selectedIndex.
Again any help is greatly appreciated.

Your itemRenderer is not a ComboBox, it is a VBox containing a ComboBox.
The DataGrid sets the .data property on the VBox and you haven't written
the code to pass it on down to the ComboBox.
You can either write that code, or use ComboBox as the top-level tag so
you are really using a subclass of ComboBox as the renderer, which is
the recommended practice.

Subject: [flexcomponents] Struggling with itemRenderer in DataGrid
Help.
I posted this on FlexCoders with no response, so I thought I would try
here too.
I'm trying to use an itemRenderer to create a comboBox in a DataGrid
that is being created with AS.
I can create the comboBox, but I am struggling with being able to change
the dataProvider for the rendered comboBox, and setting the selected
index on the comboBox.
The relevant code I am using is below.
Any help is GREATLY APPRECIATED as I am rapidly approaching a deadline.
Steve
public function createPositionTable():void
{
_datagrid = positionsGrid; // positionsGrid is an already created
DataGrid object
_col1 = new DataGridColumn;
_col2 = new DataGridColumn;
_col3 = new DataGridColumn;
_col4 = new DataGridColumn;
_col5 = new DataGridColumn;
_col1.headerText= "Position";
_col1.dataField = "Description";
_col1.editable = true;
_col1.width = 100;
_col2.dataField = "Type";
_col2.headerText= "Type";
_col2.editable = true;
_col2.width = 50;
_col3.dataField = "levelCode";
_col3.headerText = "Level Code";
_col3.width = 150;
_col3.editable = false;
_col3.itemRenderer = new ClassFactory(cbRender); // HERE IS WHERE I
AM CREATING THE COMBO BOX
_col3.editorDataField = "levelCode";
_columns = new Array(_col1,_col2,_col3);
_datagrid.columns = _columns
_datagrid.sortableColumns = false;
_datagrid.dataProvider = objAdminTableGridDP;
_datagrid.dragEnabled = false;
_datagrid.dragMoveEnabled = false;
_datagrid.dropEnabled = false;
_datagrid.editable = true;
_datagrid.rowHeight = 30;
updateTablesButton.label = 'Update Positions Table';
}
