If you need to show a list of selection items with image in it, you need to search at Owner Draw ComboBox or Owner Draw ListBox control. In these controls, you can display an image of an item with text if you want. Once a user selects that item, you can show other controls on the order form. If you are using Windows Forms or WPF to build your application, you can simply put a Panel on the Form and show this panel when an item is selected in the selected items list. So in your left side or at the top of the form, you should display list of available items. By default, you will see only list of items on the Form. Once an item is selected, you show the Panel by using its Visible = True property. Based on the selection, you can also create/manage your controls to be displayed on the panel. I hope this points you to the right direction :) Good luck.
