I want a ComboBox which has no drop-down button but can still be opened when I click on the text in the ComboBox. Is this possible with a WPF ComboBox?

Dispatcher.BeginInvoke(new Action(() =>
            {
                ToggleButton dropDownButton = GetFirstChildOfType<ToggleButton>(cboMedicos);
                if (dropDownButton != null)
                {
                    dropDownButton.IsEnabled = false;
                }

            }), System.Windows.Threading.DispatcherPriority.Render);




        public static T GetFirstChildOfType<T>(DependencyObject dependencyObject) where T : DependencyObject
        {
            if (dependencyObject == null)
            {
                return null;
            }

            for (var i = 0; i < VisualTreeHelper.GetChildrenCount(dependencyObject); i++)
            {
                var child = VisualTreeHelper.GetChild(dependencyObject, i);

                var result = (child as T) ?? GetFirstChildOfType<T>(child);

                if (result != null)
                {
                    return result;
                }
            }

            return null;
        }
