Andrew, I had created a custom DataGrid that overrode the setFocusedCell function. This allowed me to create my custom TextInput as the cell editor and add a listener on the cellFocusOut event. This listener populated the event object value and colName attributes. The purpose of using this approach was to have the flexibility to create a different cellEditor for each column. However, since this approach seems overly complex and does not seem to port well to Flex 2.0, I used the cell renderer approach that Doug and bod suggested. Thanks!
