Answer 2

Here is what I have done, I wrote a simple function, when I click a Button, I Select Only the Panel Control and pass it to a function for further loop through the control on that panel.

private void cmdfind_Click(object sender, EventArgs e)
    {
        try
        {
            foreach (Control control in this.Controls)
            {
                if (control.GetType() == typeof(Panel))
                    //AddToList((Panel)control); //this function pass the panel object so further processing can be done 
            }                         
        }
        catch (System.Exception ex)
        {
            MessageBox.Show(ex.Message);
        }

    }

try this

foreach (var control in this.Controls)
{
   if (control.GetType()== typeof(Button))
   {

       //do stuff with control in form
   }

   else if (control.GetType() == typeof(Panel))
   {
       var panel = control as Panel;
       foreach (var pan in panel.Controls)
       {
           if (pan.GetType() == typeof(Button))
           {

                //do stuff with control in panel
           }
        }
    }              

}
