         LoopControls(panMainContent.Controls);
}

private void LoopControls(controlCollection)
{         
        foreach (Control control in controlCollection)

                var menuControl = (CheckBox)control;
                if (menuControl.Checked)
                {
                     //do something
                }
            }
