[flexcoders] DataGrid rendering

[dontlament]

I have a large dynamic datagrid with 4 dropdown filtering options to
compare a large database of products.  The design of the site and
datagrid is calling for a lot of custom style.  The issue I am having is
there seems to be no mechanism to track when a datagrid has finished
rendering, so I can hide it as the styles are applied, so I am getting a
very ugly and clunky render of the datagrid.  Has anyone had this issue
before, or anyone have any suggestions on how to circumvent this
problem?
