Right click the combo box control, create a property node "Strings[]"
(Create>Property Node>Strings[]). Put the desired names in it
through this property node.

I have a very similar hurdle to get over. I would like to have a combo box or list box, which is populated by previously selected options. The list will be further populated as more choices are made over time. I'm almost positive that property nodes are the way to go here, but how exactly would one do this?

It's been a while since people have posted on this thread, so I guess I'm hoping for a miracle response here. thanks in advance

Did you open S G's example in message #8?

You build your list of options into a string array and pass it to the Strings[] property node of the combo box.

RavensFan,

I understand how to achieve a ComboBox control behaving like an indicator. The coding from S G will display an string array control and the ComboBox. I don't quite want that.

I really want to have a Combo or ListBox populated from a listing of items. These items will come from some pre-defined listing I create, somewhere else. Also, the list could/would ideally grow as new items are created in a separate, create-an-item method. These are some of the subtle differences in what I am trying to achieve vs. what was shown in the thread.

What does his example have to do with a combobox as an indicator?

His example shows how to programmatically populate the list of items in the combobox  If you want to grow the list, then you add items to the array and wire the array to the Strings[] property node he has shown.  You can maintain the list of strings in a shift register if needed.

Here is a more detailed example.  If your differences are more subtle, then you are going to have to explain a little bit more.
