datagrid - cell and header formatting - pls help!

[marmite]

:'(

 

I'm going mad, if not there already!

 

All I want to do is format my dataGrid so that headers align centrally, and data in the cells align right (for numbers) and centre (for text). I would also like to format numbers >1000 with a thousand comma separator...

 

I'm using AS3 in CS4 with deadline approaching.

 

Is this what I have to do:

1) Set up a .as file, and call it MyCellRenderer.as

2) Put a package{} in this .as file, and enter a Class and Function called MyCellRenderer and MyCellRenderer() respectively

3) Put a movieClip in my .fla library and name it MyCellRenderer with link to class MyCellRenderer

4) Do I also reference the .as file in the Class line under Properties at the stage level in my .fla?

 

This seems a lot of effort to align some text!

 

And it doesn't work! I get error #2007 "Parameter child must be non-null" from this line in my .fla code: myDataGridColumn.cellRenderer = "MyCellRenderer"

 

Going insane

PS. Sorry - this is in Actionscript 3 and I know I should use Flash forums but this is the one forum that always helped!
