I need to have a radio button list (Event Type) on the insert and edit templates that, when selection is changed, another drop-down resource (Event Category) is refreshed with a different data source containing the categories for the selected event type.
I'm not really certain how to begin. What postback event do I use to re-populate the categories list? Can you provide a code sample that shows how this might be done?
Thanks!!
