how to force a DataTable to redraw the visible part of itself

[leemthai]

Sometimes I regenerate the rows and columns in a DataTable but the visible part of the table does not refresh properly. The label column is missing.

As a user, to 'fix' it I can either move the mouse left or right a bit (and the datatable instantly redraws properly) or use the mouse scrollwheel to scroll down and get a 'double view' of both:
a) the part that didn't redraw correctly
b) the part that was initially off-screen

After regenerating rows and columns for a DataTable is there a call I make to ensure the visible part is repainted ?

Somehow the initial repaint is happening before the DataTable has finished being regenerated maybe?

Any tips or clues as to what is going wrong here?I'm pretty lost ...

I think this shows it better, perhaps:

That isn't typical behavior of the DataTable. You would need to share code for us to understand what is going on. Ideally a short example that we can run here.

I've actually had this "disappearing label column" quite a few times now. But when I rationalize my code it seems to magically disappear so I guess its various bugs in my stuff. I need to apply "KISS" more :)
