Refreshing radio buttons selections

[Marcelo]

Hi,

I have the fillowing scenario:

A header with 3 radiobuttons and n lines, each with 3
radiobuttons too... when I select a radiobutton on the
header, all the line radiobuttons should follow the
selection of the header... Everything is working fine, it
receives the right postback, I update the database and all
that, BUT, the controls keep rendered as before...
Is there anyway of forcing them to "repaint"? I didn't get
it working, even making their selection hardcoded...
I don't know if it makes any difference, but each line is
grouped...

TIA

Marcelo
