I think this should work:

foreach(c; control.controls)
{
     TabPage t = cast(TabPage)c;

     if(t !is null)
     {
         foreach(ctrl; t)
         {
             TextBox textBox = cast(TextBox)ctrl;

             if(textBox !is null)
             {
                 // ....
             }
         }
      }
}
