Manipulate style/classes after all controls are being created - how?

DC
Hi,

I am writing a "print control" routine which expects the id of a
control and will then make every element but the one that is supposed
to be printed invisible (only by using "display: none" style;
Visible=false causes a lot of collateral damage in my scenario).

I thought if I put this into "OnPreRende r" I will catch all controls
in the state they will have in the page render method, but if there
are e.g. databound controls that are being setup in the
control_prerend er method (for good reason, actually) then the
"display: none" style information may be overwritten by that method
since the page OnPreRender executes before the control's PreRender.

Is there a good time to manipulate the control tree knowing that the
alterations being made are the last ones before rendering, or a
different approach to my aim?

TIA for any hints!
Regards

You can hook to a number of events to accomplish this, one possiblity
is:

protected override void OnInit(EventArg s e)
{
Page.PreRenderC omplete += new EventHandler(Pa ge_PreRenderCom plete);
}

void Page_PreRenderC omplete(object sender, EventArgs e)
{
// do the style thing
}

Cheers

I think a lot of this is definately a question of personal programming style, but I'm new to Java and would like to hear a few opinions. I'm writing a control panel for an application that runs separately. The control panel is basically (almost) fully self contained. It consists of a tabbed pane with 5 different tabs. Each tab has a number of different controls -- basically all the "commonly used" controls (buttons, lists, comboboxes,...
