With a simple extension method to ControlCollection to flatten the control tree you can use LINQ to query the control tree:
public static class PageExtensions
{
public static IEnumerable<Control> All(this ControlCollection controls)
{
foreach (Control control in controls)
{
foreach (Control grandChild in control.Controls.All())
yield return grandChild;
yield return control;
}
}
}
Now I can do things like this:
// get the first empty textbox
TextBox firstEmpty = accountDetails.Controls
.All()
.OfType<TextBox>()
.Where(tb => tb.Text.Trim().Length == 0)
.FirstOrDefault();
// and focus it
if (firstEmpty != null)
firstEmpty.Focus();

/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode.rem { color: #008000; }
.csharpcode.kwrd { color: #0000ff; }

}
