Re: Changing controls after an event

Tech-Archive recommends: Fix windows errors by optimizing your registry

You're going to need to have some state information somewhere that tells your server code what controls to recreate upon postback. You should recreate these controls in Page_Init (if it's directly in the Page) or override CreateChildControls, or if it's an ASCX then Page_Load is also a fine place to recreate these controls.

Ah, can't do that as the forms are gernerated from data.. I just have
some code that's called for all forms so that I can put any special
coding for onchange in if needed.

Adrian,

The easiest way is to prepare all controls in design time and switch
their visibility on events.

I have a form with some controls on it, one of them has an auto
postback onchange.  So the postback occurs but before the event
fires, all the controls are recreated. so my question is, if the
event requires you to replace a control with another type, e.g.
replace a textbox with a date control, how do I get it to redo the
form with the new control, force another postback ?  if so , how ?

Thanks
