In researching on the internet it seems the vb.net equivalent to vba's ListIndex should be SelectedIndex.
However this does not seem to be a property of the combobox in ArcGIS when the combobox is created as an add-in?
Anyone find a way around this outside of rebuilding the combobox in a form to gain all the vb.net funcionality? I'd really like to keep it a simple add-in as that is all I need for everything other than this...
I've been searching for the same thing, apparently, the comboBox as addin does not seem to work as usual as on a windows form (suh as "SelectedItem", SelectedIndex, SelectedValue, etc.). So, my work around it, was to create a form and Add a comboBox on a form instead of having it as an addin. Not really convenient but that is a work around!
