I am trying to get to a label control to get its Text value. from a previous
page.

The label control is buried in a Web User Control that is in a webpart
zone. When I use this code:
foreach(Control c in PreviousPage.Controls)
{
and try to find the control here.

}

I can only see the masterpage, then another loop inside that gets me some
literal controls etc.

I cannot even find the Web Part Zone! Please help, is there an easier way to
do this?

Thanks,
Bryan

store the value in the page postback (session, db, etc) and then read it in
on page2.

True, but I was just trying to use the new functionality in 2.0.

If anyone can help using cross page posting using 2.0 that would be great!

Thanks!
Bryan

Hi Bryan,

As for your scenario, the Previous Page's control hierarchy is very
complex, I'd suggest that we first define a public property in the previous
page's page class to expose that certain inner control. for example:

================
public Label InnerLabel
{
get
{
    WebPart hw = WebPartZone1.WebParts[0];
    UserControl uc = hw.FindControl("HelloWorld1") as UserControl;
    Label lbl = uc.FindControl("lblMessage") as Label;

    return lbl ;
}
}

==================

then, you can access this propety in the perviouspage instance (through
reflection or strong typed instance) in the target post page's code.

Stephen suggestion is good. I also have some additional information
that shows how to use the strongly typed PreviousPage:

Hi Bryan,

How are you doing on this issue, does the suggestion in my last reply helps
a little? If there're anything else we can help, please feel free to post
