Avoid execution of "Page_Load" of controls contained in MultiViewViews

Hi,

the subject says it all. Since visible=false controls will still run
though Page_Load, I was hoping that the MultiView would somehow manage
to avoid a Page_Load of controls in its inactive Views. But of course
it does not.

I guess a safe way to avoid Page_Load is to only add the controls at
runtime into the activated view. Which of course neglects the beauty
of editing the layout if several views in one ascx.

Is there a more elegant way or at least a way to safely jump out of
Page_Load of the control (without checking the state of the parents,
please - since the control is not supposed to work in a View only).

TIA for any hint,

Regards
DC
 
I suppose you could put them in an ascx file and dynamically load them
using LoadControl() but, the only way this will work is if you never
switch views as part of a post back OR you don't use viewstate.

The reason it loads all of the controls is so that it can re-establish
the state of the objects.

I believe that the "Visible" property automatically checks the visibility of
parent/container controls. So you could try:

public void Page_Load(blah,blah,blah)
{
if (this.Visible)
{
DoYourWork();
}
}

Thank you, Scott. This works in most situations. It is however
unreliable, because visibility of the control may be changed after the
Page_Load (but before Render).

Thanks, Dave. I was hoping that I only have to make sure that the
controls which are actually postback targets exist. I am unsure about
how "complete" the control tree must be for postbacks/viewstate to
work. I will try out.
