c# - Listing all nested user controls from a master page on page load -

on page load there way enumerate nest user controls specific page load?

i'd able enumerate user controls implement interface, , call interface method controls before asp.net passes control thier page_load events.

the problem master page level, page in app loading, , each of them have random user control, , need type reference determine if implement interface, , call method.

does have ideas?

would work?

void processcontrols(control control) {     if(control imyinterface) //whatever interface name     {         (control imyinterface).methodname();     }      foreach(control child in control.controls)     {         processcontrols(child);     } }
