[thelist] (asp.net) accessing controls created at runtime.

[Peter Brunone (EasyListBox.com)]

Not just define (Dim) it; *create* it there.  If you add it to the page structure, then it's not going to go away like a variable which only has local scope.

 From: "Tab Alleman" talleman at Lumpsum.com

So you're saying I should DIM the control in page_init, but where do I "FindControl()" it? Still in page_init, or in the submit_click event handler?
