AdvancedDataGrid | Header Renderer | Tabs Support

Hi

I have advanced datagrid. It has few columns which have header renderer.
All the header render inherit from <s:MXAdvancedDataGridItemRenderer>. Each
header render has textinput. I want to enable tabbing between these header
renders. I want to put some text and then tab to another control in the
other header.

How to do this??

Any pointers will be appreciated.
