Combox tied to Label for enable/disable

I am using the following code to create a combo box with a label above it in the ribbon. The item 1, 2, 3 are really going to be pictures. The reason I want the label above is that there is a "left" and "right" combo box for our application. I cannot figure out a ncie way of setting the label to be disabled whenever the combo box is and vice versa. I cannot use the label feature of the combo box itself as there's no way I know of to make this visible and above the combobox instead of to the left. I am using the command design to facilitate enabling and disabling the combobox. How can I nicely tie the label to the combo box?
