Loop through all the user controls on a page

Question

Want to loop through all the user controls that exist on the page and get their IDs. How do I do it?

Answer 1

This should work:

var listOfUserControls = GetUserControls(Page);

...

public List GetUserControls(Control ctrl)
{
  var uCtrls = new List();
  foreach (Control child in ctrl.Controls) {
    if (child is UserControl) uCtrls.Add((UserControl)child);
    uCtrls.AddRange(GetUserControls(child);
  }

  return uCtrls;
}
