ASP.Net: Controls on a webform

Hi,

I create a webform, and put some html-controls and webform controls on it, give them a name and a text for example.
When i press a button, i want all the controls be written in an xml file: the type, name and text has to be written in it.

Does anyone have an idea where i can find all the controls on my form?

In vb6 this was possible:

VB Code:

dim k as control
for each k in me
      debug.print k.name
next
