In a propertygrid I want to create a combotree control with multiselect values.
The items are all defined with id/name (
http://www.geologix.ch/downloads/testdata.json). On my server I only save the selected values, e.g. "1,22,4". As display value I would like to show the names ("First, Second Child, Third").
What is the correct approach to implement this in a general way? Where do I have to add the functionality?
